Published May 17, 2026; applicable to the 2026 ARAM Mayhem ruleset and the current live League of Legends patch used by ARAM Mayhem queues, with base ARAM reroll and champion bench behavior cross-checked against Riot Games' ARAM systems, the League client, LoL Fandom's patch-maintained ARAM documentation, and current champion-performance references such as Lolalytics, U.GG, League of Graphs, Mobalytics, OP.GG, and ARAMayhem.com.

What Dice Rerolls Actually Do in ARAM Mayhem

The dice reroll in ARAM Mayhem has three practical jobs: it gives the player a new random champion, sends the previous champion to the shared bench when bench space allows, and indirectly increases the team's total champion options before the loading screen. That sounds similar to regular ARAM, but the value is different in Mayhem because champion power is shaped harder by accelerated fights, mode-specific tempo, and high-impact enhancement choices. A reroll is not just a personal escape button from a disliked champion; it is a team resource that can create a frontline, rescue the damage profile, or unlock a stronger enhancement path.

Riot's ARAM system, documented in the League client and summarized on LoL Fandom's ARAM page, allows players to store up to two rerolls and use them during champion select. When a player rerolls, the old champion normally moves to the champion bench, where teammates can swap into it. In ARAM Mayhem, that bench matters even more because a champion that looks average in normal ARAM can become premium when its kit abuses Mayhem's faster skirmish rhythm. For example, a player who rerolls away from Maokai may think they escaped a low-damage tank, but the team may have just gained a reliable engage-and-zone option from the bench that pairs perfectly with poke mages and reset carries.

The cleanest way to understand how rerolls work in ARAM Mayhem is to separate ownership from access. The dice belongs to one player, but the result affects all five players. One click can add two usable options to the lobby: the newly rolled champion and the benched champion. In a mode where one missing role can decide the first three fights, that extra option often matters more than personal comfort. In my own Mayhem games, the lobbies that win early usually do not have five flashy champions; they have one clear engage tool, one durable body, one sustained source of damage, and enough follow-up to punish enemies after the first crowd control lands.

The Best Time to Use Dice in ARAM Mayhem

The best time to use dice in ARAM Mayhem is after checking the first five champions for four concrete needs: frontline, engage, sustained damage, and pilot reliability. Do that check before anyone panic-rerolls. A team with Lux, Xerath, Ziggs, Jhin, and Seraphine looks comfortable from range, but it has no durable initiator and weak objective control once enemies survive the first spell rotation. In that lobby, 1 player should spend 1 dice before the timer drops below the final swap window; the desired result is any champion that can start or absorb fights, such as Amumu, Leona, Nautilus, Sion, Zac, Galio, or Alistar. The action is simple: identify "zero frontline," use one reroll, then immediately ping the bench if a tank appears.

Use a reroll when the team lacks reliable engage. Mayhem rewards teams that can force fights on their own timing because enhancement spikes and short death cycles create repeated brawls. A composition with Varus, Kai'Sa, Hwei, Milio, and Karthus has damage, but if every fight starts with the enemy Malphite pressing R first, your damage never gets to choose the angle. The correct dice action is to reroll the lowest-value duplicate backliner, not the only scaling carry. One reroll that finds Rakan or Wukong can turn five disconnected damage dealers into a comp that lands 1 engage, chains 2 follow-up spells, and wins the fight before the enemy poke pattern stabilizes.

Use a reroll when sustained damage is missing. ARAM Mayhem has many explosive moments, but teams still lose when all damage comes from long-cooldown poke or one ultimate. A lobby with Malphite, Blitzcrank, Nami, Zoe, and Nidalee can kill one target, then run out of pressure. The correct move is to spend dice looking for a champion that continues hitting after the first burst: Azir, Cassiopeia, Kog'Maw, Kayle, Corki, Ryze, Jinx, Twitch, or even bruisers like Gwen and Bel'Veth depending on the active Mayhem tuning. The result you want is 1 sustained threat protected by 2 utility pieces, not another single-combo champion.

Use a reroll when champion mastery is too low for the role the team needs. This is not about ego; it is about execution. If the only engage is Qiyana in the hands of someone who has never played her, that is not a functional engage slot. The better action is to spend 1 dice or ask the lobby for a bench swap. A familiar Braum, Vi, or Sejuani will outperform an unfamiliar "stronger" champion because Mayhem fights give less time to slowly learn spacing. In 1500-plus ARAM Mayhem games, the most painful losses have come from teams protecting a theoretical S-tier pick while the assigned player clearly cannot execute the first two fights.

Do Not Blindly Reroll High-Value Champions

The biggest mistake in any ARAM Mayhem reroll guide is treating disliked champions as disposable. A champion should be rerolled only after comparing its current value against the team's missing pieces and the mode's enhancement rewards. Current champion strength should be checked through patch-specific pages on Lolalytics, U.GG, League of Graphs, Mobalytics, OP.GG, or ARAMayhem.com rather than old tier lists, because Riot balance adjustments and ARAM-specific modifiers change how hard a champion can carry. The practical rule is firm: do not reroll the only champion that solves a team problem unless the bench already contains a replacement.

For example, do not instantly reroll Ornn just because tanks feel less exciting than assassins. If the other four champions are Syndra, Ezreal, Brand, and Sona, Ornn gives the team 1 frontliner, 1 long-range engage threat, 1 item-upgrade scaling angle where available under the current rules, and a safe body to stand between poke champions and divers. Rerolling Ornn into another mage may increase personal fun for 30 seconds, then remove the structure that lets the whole team play. The better action is to keep Ornn, ask a teammate with a weak duplicate damage champion to roll, and preserve the only initiation slot.

Also avoid rerolling champions that scale unusually well with Mayhem-style enhancement choices. Champions with repeatable spell casts, reset patterns, shields, summons, or persistent zones often gain more from mode modifiers than their normal ARAM reputation suggests. Swain is a strong example: in ordinary ARAM he is already built around extended clumped fights, but in Mayhem he becomes more valuable when fights happen constantly and enemies are forced into tight spaces. A player who rerolls Swain because he is "not flashy" may give up a champion that turns 1 successful snowball or root into 5 seconds of zone control and a won brawl.

Cold-looking champions deserve a second check before being thrown away. Taric, Renata Glasc, Zilean, Ivern, Braum, and Milio are easy to underrate in solo queues because they do not top damage charts. In ARAM Mayhem team comp reroll strategy, they can be the exact pieces that let high-damage allies survive the first engage. If the bench already has three carries, keeping Renata can be better than fishing for a fourth. The result is measurable in fights: 1 hostile bailout or resurrection denial can flip an enemy reset chain, while another carry often dies before contributing.

Solo Dice Use vs Team Reroll Strategy

Solo dice use is simple but limited: one player rerolls to improve personal champion comfort. Team dice use is stronger: five players coordinate rerolls to build a complete composition. The difference shows up before minions spawn. In solo use, a player sees Bard, dislikes Bard, presses reroll, and locks whatever appears. In coordinated use, the team says, "We have poke and support, need engage or DPS," then the least essential player spends dice first. That one sentence prevents wasted rolls.

The ARAM Mayhem champion bench explained in practical terms: the bench is a temporary shared draft pool created by rerolls. Every champion on that bench should be treated like a puzzle piece. If someone rolls away from Nautilus and the team currently has no engage, the correct action is for the most comfortable tank player to swap into Nautilus within 5 seconds, then announce that the engage slot is filled. That quick bench communication produces a direct result: remaining dice can now hunt for damage or anti-dive instead of duplicating the same role.

Team reroll order matters. The weakest fit should roll first, not the strongest player's favorite champion. If the starting lobby is Darius, Leona, Samira, Lulu, and Viktor, the team already has engage, frontline, burst follow-up, support, and magic damage. Burning dice here is optional and should be limited to a player who cannot pilot their champion. If the starting lobby is Teemo, Nidalee, Zoe, Yuumi, and Janna, the comp lacks a body and reliable sustained damage; 2 players should reroll before any swaps are finalized. The expected result is either one frontline champion or one auto-attack carry. If neither appears, keep the best poke setup and use summoner spell choices and early positioning to protect the backline, rather than randomly cycling away the only coherent damage source.

Communication does not need long debate. Use short commands: "Need tank," "Bench Brand, take it if mage," "Do not drop Jinx," "I can play Amumu," "Roll one more for DPS." These calls are better than silent panic. In Mayhem, champion select is the first fight. A team that spends 20 seconds assigning roles enters the bridge with a plan; a team that spends 20 seconds rerolling for personal highlights enters with five unrelated champions.

Common Reroll Mistakes That Lose ARAM Mayhem Games

Mistake 1: Instant rerolling at the start of champion select

Opening with a blind reroll wastes information. The first 5 seconds should be used to read all five champions, identify missing roles, and scan player comfort through quick chat or swaps. If someone instantly rerolls Shen before seeing that the other four champions are all fragile damage dealers, the team may lose its only frontline. The fix is strict: wait until all initial champions appear, count frontline-engage-DPS-support in that order, then spend dice. One 5-second pause often saves one irreplaceable role.

Mistake 2: Abandoning cold or unpopular champions too fast

Cold champions are not automatically weak in ARAM Mayhem. Some unpopular picks become excellent because they answer the exact chaos of the mode. Braum blocks projectile-heavy Mayhem fights, Zilean denies burst resets, and Poppy shuts down dash engage from champions that thrive in accelerated skirmishes. The fix is to judge function first: if the champion provides 1 unique defensive answer that no teammate has, keep it or place it on the bench for a specialist. The result is fewer games lost to one enemy diver repeatedly starting fights for free.

Mistake 3: Ignoring the team's damage structure

A team can have five "good" champions and still have a bad damage structure. If all five deal magic damage, enemy tanks can stack magic resistance and walk forward. If all damage is poke, the team can lose every all-in after cooldowns are used. If all damage is short range, the team may never touch a siege composition. The fix is to check damage in 3 categories before using dice: physical, magic, and sustained. If the team already has Brand, Zyra, and Fiddlesticks, do not reroll the only ADC unless a better sustained physical source is on the bench. Keeping 1 physical carry changes enemy item pressure and gives the team a reliable way to finish tanky targets.

FAQ: ARAM Mayhem Dice and Champion Bench

How do rerolls work in ARAM Mayhem?

Rerolls replace the player's current random champion with another random available champion, while the previous champion usually moves to the shared bench if the bench can accept it. Riot's base ARAM reroll and bench behavior is visible in the League client and documented by LoL Fandom, while ARAM Mayhem-specific value comes from the mode's faster fights and enhancement-driven power spikes. The correct use is to treat every reroll as 1 personal change plus 1 possible team bench option.

What is the best time to use dice in ARAM Mayhem?

The best time to use dice in ARAM Mayhem is after the team identifies a missing core role. Roll when there is no frontline, no engage, no sustained damage, or when the only required-role champion is being held by a player who cannot pilot it. Do not roll before checking the full lobby. A clear example: with four ranged poke champions and no tank, spend 1 dice to search for engage; with a balanced comp already showing tank, carry, mage, and support, save dice unless a player needs a comfort fix.

Should high-tier champions always be kept?

High-tier champions should be kept when they fit the team's needs and the player can execute them. Patch-specific strength should be checked on current Lolalytics, U.GG, League of Graphs, Mobalytics, OP.GG, or ARAMayhem.com pages because ARAM modifiers and Mayhem rules change champion value. A strong champion that creates the fifth magic-damage slot may be worse than a lower-ranked physical carry that fixes the team's damage balance.

How should teams use the ARAM Mayhem champion bench?

The bench should be used as a shared draft board. When a useful champion appears, the player best suited for that role should take it quickly. If Nautilus, Sejuani, or Rakan appears on the bench and the team lacks engage, assign it immediately. If Jinx or Kog'Maw appears and the team lacks sustained DPS, protect that pick instead of rolling over every support that can keep it alive.

Is it better to save rerolls or spend them aggressively?

Spend rerolls aggressively only when the current composition has a clear structural failure. Save them when the team already has frontline, engage, mixed damage, and at least one reliable scaling threat. The result is better long-term lobby quality: dice are used to fix losing drafts, not to chase personal highlight champions.

Action Plan for Better ARAM Mayhem Rerolls

Use a 4-step check in every champion select. First, count frontline: 0 frontline means one early dice should hunt for a durable body. Second, count engage: 0 engage means the lowest-value backliner should reroll before carries are touched. Third, check damage structure: keep at least 1 sustained damage source and avoid stacking all magic or all burst. Fourth, confirm pilot comfort: a playable B-tier champion in the right hands beats an S-tier champion misplayed in the first two fights.

The strongest ARAM Mayhem reroll guide can be reduced to one disciplined habit: roll to complete the team, not to escape boredom. One smart dice use can place a tank on the bench, free a carry from a bad matchup, or give the team the sustained damage needed to win repeated Mayhem brawls. The players who climb the quality of their games are not the ones who always get perfect champions; they are the ones who turn 2 rerolls, 1 bench swap, and 15 seconds of communication into a coherent five-player plan.
