Published May 17, 2026; applicable to the current ARAM Mayhem live build as shown in the League of Legends client and the ARAM Mayhem tooltip database on aramayhem.com.

Rock Solid changes the rune conversation for Xin Zhao and Cho'Gath because ARAM Mayhem is not normal Howling Abyss with a faster scoreboard. The mode compresses fights, rewards repeated engages, and punishes one-death frontliners harder than standard ARAM because every failed entry immediately becomes a numbers-down brawl. In that environment, the question is not "Which rune page has the most theoretical damage?" The better question is: "Which page lets Xin Zhao or Cho'Gath survive the first 3 seconds, force enemy cooldowns, and still have enough health to win the second rotation?"

Sources used for this guide: current in-client rune and item tooltips from Riot Games' League of Legends client, Riot's official patch notes on leagueoflegends.com, champion spell references from the League of Legends Wiki on lol.fandom.com, ARAM Mayhem augment references from aramayhem.com, and public ARAM discussion patterns from r/ARAM and major ARAM Discord communities. Live numbers can shift between patches, so the final authority for Rock Solid's exact value is always the in-game ARAM Mayhem tooltip before champion select ends.

Why Rock Solid Is Different on Xin Zhao and Cho'Gath

Rock Solid is valuable because it converts a frontliner's first contact into a safer engage window. In regular ARAM, a tank can sometimes wait for a clean snowball or stand behind minions until the enemy mispositions. ARAM Mayhem gives less patience. Burst chains arrive faster, flank angles are limited, and teams often commit earlier because augments create stronger first rotations. A durability-focused augment such as Rock Solid is strongest when the champion can turn that extra survival into a guaranteed crowd-control event or a second spell cycle.

Xin Zhao uses Rock Solid as an anti-burst entry tool. His job is to move from neutral space into melee range, cast Audacious Charge , stack Three Talon Strike , and use Crescent Guard to deny ranged retaliation. If Rock Solid keeps him alive through the first hostile stun, he can complete 3 actions: dash in, knock up one target, then ult to isolate the fight. The result is a real engage instead of a 1-second death animation. That is why Xin Zhao survival runes ARAM Mayhem should prioritize tenacity, healing access, and burst resistance over pure attack-speed greed.

Cho'Gath uses Rock Solid in a slower but more oppressive way. His value comes from body-blocking, landing Rupture , silencing with Feral Scream , and threatening Feast on low-health targets. Rock Solid gives him more time to stand in the front pocket, absorb poke, and keep enemies inside threat range. A Cho'Gath who survives 5 extra seconds can cast 1 more Rupture , deny 1 dash with silence, and secure 1 Feast stack or execute. That makes Cho'Gath tank runes ARAM Mayhem more health-and-control focused than Xin Zhao's page.

Best Rock Solid Rune Pages for Xin Zhao

Xin Zhao Page 1: Resolve + Precision, the safest default

The most reliable Rock Solid Xin Zhao page is Resolve primary with Precision secondary : Grasp of the Undying, Shield Bash or Demolish depending on available item shielding, Second Wind, Unflinching, Triumph, and Legend: Tenacity. Riot's client tooltip identifies Grasp as a combat rune that rewards repeated champion contact, while Triumph and Legend: Tenacity come from Precision's takedown and crowd-control resistance tools. This page is the best defensive setup when the enemy has 2 or more hard crowd-control champions such as Leona plus Syndra, or Nautilus plus Veigar.

The action pattern is simple: take 1 short trade with Audacious Charge , trigger Grasp on the nearest target, step backward after the knock-up, then re-enter once Rock Solid and item defenses have absorbed the first burst. In a real ARAM Mayhem fight, this creates a measurable result: 2 controlled entries instead of 1 desperate all-in. From 1500+ Mayhem games, the Xin Zhao deaths that lose games usually happen before Crescent Guard is pressed. Resolve primary reduces that exact failure point.

Xin Zhao Page 2: Precision + Resolve, when damage cannot be ignored

If the enemy team has 3 squishy champions and only 1 reliable peel tool, Precision primary is stronger: Conqueror, Triumph, Legend: Tenacity, Last Stand, with Second Wind and Unflinching secondary. Conqueror is documented in Riot's rune system as a stacking combat rune, and Xin Zhao stacks it quickly through dash, auto attacks, Three Talon Strike , and Wind Becomes Lightning . Rock Solid covers the missing tankiness long enough for Conqueror and Triumph to matter.

Use this page only when Xin Zhao can realistically hit for 4 seconds after entering. Example: against Jinx, Xerath, Seraphine, Wukong, and Nidalee, Precision primary lets Xin Zhao pressure the backline because the enemy has poke but limited instant lockdown. The sequence is 1 dash onto the closest carry, 3 attacks to finish the knock-up, 1 ultimate to reject ranged damage, then 1 Triumph reset after the first takedown. The result is sustained threat instead of being a low-damage wall.

For items, pair these pages with durability that supports repeated contact. Sterak's Gage has historically provided a lifeline-style shield for bruisers according to Riot item tooltips and LoL Wiki item documentation; Spirit Visage increases healing and shielding effects when available in the current item set; Jak'Sho-style resistance scaling, if present on the live patch, rewards long fights. The practical build logic is: buy 1 health item, 1 resistance item matching the strongest enemy damage type, then 1 sustain or shield amplifier. Rock Solid protects the first entry; items protect the second.

Best Rock Solid Rune Pages for Cho'Gath

Cho'Gath's best defensive page is usually Resolve primary with Inspiration secondary : Grasp of the Undying, Demolish or Font of Life, Conditioning, Overgrowth, then Approach Velocity and Biscuit Delivery or Cosmic Insight depending on the live rune set. The League client lists Overgrowth as a health-scaling rune and Conditioning as a delayed resistance rune; both fit Cho'Gath because his champion identity already rewards maximum health through Feast , as documented in Riot's champion tooltip and LoL Wiki's Cho'Gath ability page.

This is the cleanest best defensive runes for ARAM Mayhem choice when Cho'Gath must be the only true frontline. The action pattern is 1 step forward to bait a spell, 1 Rupture under the enemy's retreat path, 1 Feral Scream after the knock-up, then 1 Feast on the lowest legal target. Rock Solid keeps Cho'Gath from losing half his health before he can reach silence range. Overgrowth and Feast then turn every extended fight into more future durability.

There is also a more aggressive tank-control page: Resolve primary with Precision secondary, taking Triumph and Legend: Tenacity. This page is better when the enemy has enough crowd control to interrupt Cho'Gath's walk-up. Example: against Morgana, Ashe, Lux, Maokai, and Varus, Inspiration movement tools may not save him once chained crowd control begins. Tenacity plus Rock Solid gives him one specific result: survive the first snare-arrow-root chain with enough health to cast silence before the second enemy spell rotation.

Cho'Gath itemization should multiply health into useful resistance. Heartsteel-style health stacking is attractive in brawl-heavy modes when it exists on the patch, but raw health without armor or magic resistance gets shredded by percent-health damage. A stronger ARAM Mayhem tank curve is 1 health mythic or core tank item, 1 armor item into marksmen and AD bruisers, 1 magic-resist item into mages, then Warmog's Armor or a regeneration option only after Cho'Gath already has enough resistances to avoid instant deletion. Rock Solid improves the first 2 seconds; resistances decide whether the next 8 seconds are playable.

Xin Zhao vs Cho'Gath: Same Augment, Different Job

Xin Zhao spends Rock Solid aggressively. Cho'Gath spends it positionally. That single difference should decide the rune page. Xin Zhao wants to enter, drain cooldowns, heal from combat, and create a knock-up inside the enemy team. Cho'Gath wants to hold the bridge, threaten a zone, and make enemies walk around his silence and Feast range. A Rock Solid Xin Zhao who never engages wastes the augment. A Rock Solid Cho'Gath who dives past his carries also wastes it.

Use pure survival runes on Xin Zhao when the enemy has 2 burst threats and 2 crowd-control sources. Example: Annie, Syndra, Leona, Kai'Sa, and Jayce can kill Xin Zhao before his ultimate gets full value. Resolve primary plus Rock Solid gives him the clear action goal of absorbing 1 stun, pressing ultimate, and forcing the enemy carries backward. Keep partial damage runes when the enemy has poke but poor peel. Against Ziggs, Jhin, Nidalee, Karma, and Brand, Conqueror plus defensive secondary lets Xin Zhao punish immobile targets after the first engage lands.

Use pure survival runes on Cho'Gath when he is the only champion able to stand in front of the wave. Example: if allies are Lux, Jinx, Xerath, and Sona, Cho'Gath must run Resolve with health scaling because every lost front-space trade exposes 4 fragile teammates. Keep some utility or takedown runes when another durable ally exists. If Cho'Gath has a Sejuani or Sett beside him, he can take Triumph secondary and play for Feast executes after the other tank starts the fight.

New Players' 3 Most Common Mistakes

Mistake 1: Taking damage runes on Xin Zhao because he "needs to carry." In ARAM Mayhem, a dead Xin Zhao deals zero damage and gives the enemy a free 5v4 push. The fix is precise: if the enemy has 2 point-and-click or near-guaranteed lockdown tools, take Resolve primary, buy early health plus resistance, and use Crescent Guard within 1 second of reaching the backline. The result is a completed engage instead of a failed assassination attempt.

Mistake 2: Building Cho'Gath as only health with no resistance pairing. Feast stacks and Overgrowth make the health number look impressive, but percent-health damage and repeated mage rotations cut through unprotected HP. The fix is to match 1 resistance item to the enemy's highest repeated damage source before buying luxury regeneration. Against double AP poke, buy magic resistance before Warmog-style recovery. Against two marksmen, buy armor before chasing more maximum health.

Mistake 3: Treating Rock Solid as permission to start every fight. The augment increases forgiveness; it does not erase 5 enemy cooldowns. The fix is to count 2 enemy spells before committing. For Xin Zhao, wait until 1 stun or displacement is used, then dash. For Cho'Gath, wait until 1 mobility spell or cleanse-like escape is down, then cast Rupture behind the target. The result is a forced fight on enemy cooldowns rather than a donation into prepared damage.

FAQ: Rock Solid Xin Zhao and Cho'Gath Runes

Is Rock Solid better on Xin Zhao or Cho'Gath?

Rock Solid is more consistent on Cho'Gath because his health scaling, silence, and Feast reward long front-to-back fights. It is more explosive on Xin Zhao because one survived burst window can become a knock-up plus ultimate engage. Pick Cho'Gath for stable frontline value; pick Xin Zhao when the team needs immediate backline access.

What is the safest Xin Zhao survival rune page in ARAM Mayhem?

The safest page is Resolve primary with Precision secondary: Grasp, Second Wind, Unflinching, Triumph, and Legend: Tenacity. This ARAM Mayhem Rock Solid rune guide recommends it whenever the enemy has multiple stuns, charms, roots, or knock-ups because Xin Zhao's first 3 seconds decide the entire fight.

What is the safest Cho'Gath tank rune page in ARAM Mayhem?

Resolve primary with Inspiration secondary is the safest default: Grasp, Conditioning, Overgrowth, plus movement or cooldown utility from Inspiration. This setup makes Cho'Gath better at holding space, reaching silence range, and converting Feast stacks into meaningful durability.

Should Rock Solid users still take damage runes?

Yes, but only with a clear job. Xin Zhao keeps Conqueror when he can attack for 4 seconds after engaging. Cho'Gath keeps Triumph or utility secondary when another ally can share frontline duty. If the champion is the only engage tool, pure survival runes produce better results.

Which items work best with Rock Solid?

Rock Solid works best with health plus resistance combinations. Xin Zhao prefers bruiser durability with shielding, healing amplification, or mixed resistances. Cho'Gath prefers health scaling backed by armor or magic resistance. In both cases, 1 early resistance item matched to the enemy's main damage type gives better fight uptime than stacking raw health alone.

Action Plan Before Lock-In

For Xin Zhao, lock Rock Solid with Resolve primary when the enemy draft can burst or chain-control him before ultimate. Switch to Precision primary only when the enemy backline lacks reliable peel. The practical rule is 2 hostile lockdown tools equals survival page; fewer than 2 equals Conqueror can carry the fight.

For Cho'Gath, treat Rock Solid as a frontline amplifier. If Cho'Gath is the only wall, take Resolve health scaling and build resistance early. If another tank starts fights, add secondary runes that reward takedowns or improve cooldown access. The strongest Rock Solid augment Xin Zhao Cho'Gath guide advice is blunt: Xin Zhao uses Rock Solid to enter and live; Cho'Gath uses Rock Solid to stand forward and make the enemy walk into bad space.
