Vulnerability ARAM Mayhem Augment Guide

Vulnerable: After damaging an enemy, they become vulnerable, taking increased damage. This is a core damage amplifying rune for team composition.

"Vulnerable: Core effect: After dealing damage, enemies enter a vulnerable state, taking 15% increased damage from all sources for 3 seconds \nRefresh mechanism: Duration is refreshed by dealing damage again \nArea effect: AOE damage applies vulnerable to all enemies in range \nStacking rules: Multiplies with other damage enhancement effects \nEffect scope: Includes damage dealt by allies

Vulnerable: All basic attack damage All active ability damage Item ability damage Damage from runes

Vulnerable: Healing and shield effects, Tower and minion attacks, Reflect damage, Summoner spell damage

Brittle: Brittle effect applies to true damage. Can also apply Brittle to minions and monsters. Each tick of damage refreshes Brittle duration. Multiple Brittle effects don't stack, only refresh duration

Vulnerable: Champions with large area AOE (Jinx, Brand, Kassadin) Poke-type champions (Jayce, Ziggs, Jinx) Team-oriented supports (Morgana, Karma, Nami)

Vulnerable: Pure single-target damage dealers (Zed, Talon, Vayne)\nPure tank champions (Alistar, Leona, Ornn)\nPure burst assassins (Zed, Talon, Akali)

Vulnerable: Use AOE skills to apply vulnerable to all enemies first Continuously attack enemies to maintain vulnerable status Combine with team damage for maximum team damage Can apply vulnerable to epic monsters to speed up kills

Vulnerability + Jeweled Gauntlet: Jeweled Gauntlet enables abilities to critically strike while Vulnerability enables item damage and damage over time effects to crit. Together they provide 50% critical strike chance and multiple damage sources can crit, dramatically increasing burst potential for mages and ability-based champions in ARAM teamfights. Vulnerability + Soul Siphon: Soul Siphon provides 25% critical strike chance and heals for 12% of post-mitigation critical strike damage. Combined with Vulnerability's 25% crit chance, you reach 50% crit chance while gaining substantial sustain from both ability crits and item/DoT crits during extended ARAM skirmishes. Vulnerability + Upgrade Infinity Edge: Upgrade Infinity Edge grants 25% critical strike chance and empowers crit damage scaling. With Vulnerability's 25% crit chance, you reach 50% total crit chance. The upgraded Infinity Edge's bonus crit damage amplifies both the ability crits and item/DoT crits that Vulnerability enables. Vulnerability + Critical Rhythm: Critical Rhythm grants 25% critical strike chance and stacks bonus attack speed on crits up to 60%. Combined with Vulnerability's 25% crit chance, you reach 50% crit chance. The frequent crits from both sources maintain maximum attack speed stacks throughout teamfights. Vulnerability + Critical Missile: Critical Missile grants 25% critical strike chance and launches Firecrackers on crits against champions. With Vulnerability's 25% crit, you reach 50% chance. The frequent critical strikes from abilities and item damage trigger additional projectile damage, compounding burst output.

Avoid Vulnerability + Jeweled Gauntlet: Vulnerability explicitly states that if both augments are equipped, only the critical strike chance of the augment with higher critical damage is rolled, creating direct mechanical overlap. Both provide 25% critical strike chance and enable crits on non-basic attacks, making the second augment largely redundant and wasting a valuable augment slot. Avoid Vulnerability + Slow and Steady: Slow and Steady removes all attack speed bonuses from your attack rate, which severely limits how often you can trigger on-hit effects and item actives. Vulnerability wants frequent damage instances to roll critical strikes on items and damage over time, making the attack speed penalty directly conflict with maximizing Vulnerability's value. Avoid Vulnerability + Celestial Body: Celestial Body reduces your total damage output by 10%, which directly diminishes the critical strike damage Vulnerability provides. Since Vulnerability is an offensive augment focused on amplifying item and damage over time effects, pairing it with a damage reduction penalty creates direct anti-synergy that lowers your overall burst potential. Avoid Vulnerability + Soul Siphon: Soul Siphon grants 25% critical strike chance and heals based on critical strikes, creating partial stat overlap with Vulnerability's 25% critical strike chance. While not completely wasted, the critical chance component becomes redundant if you reach the cap, and Soul Siphon offers no synergy with Vulnerability's specific focus on item and damage over time crits.

Brittle: Don't think only your damage benefits, teammates do too. Don't ignore team benefit, this is a team rune. Don't take on pure single target, very low value. Note Brittle duration, refresh it timely.
