Glass Cannon: Prioritize AD/AP to increase bonus damage. Stay in backline in teamfights to avoid being focused. Use high damage to quickly kill enemy carries. Don't engage recklessly, maintain safe distance. Build one defensive item for survival.

Glass Cannon + Vampirism: Glass Cannon caps health at 70%, nullifying ally healing. Vampirism compensates by granting 25% omnivamp, letting you self-heal from the 15% bonus true damage you deal. This synergy transforms the health restriction into a sustainable playstyle where your amplified damage output fuels your own survivability through lifesteal. Glass Cannon + Goredrink: Glass Cannon's 15% true damage conversion synergizes with 15% omnivamp to heal you for a portion of all damage dealt. Since your health cannot exceed 70%, traditional healing is wasted, but omnivamp works on damage output. This combination maximizes damage while providing sustain that respects your health threshold. Glass Cannon + Jeweled Gauntlet: Glass Cannon's true damage boost amplifies all ability damage, and Jeweled Gauntlet lets abilities critically strike for 145%+ damage. The 15% true damage applies to the higher crit values, creating devastating burst windows. Your reduced health pool matters less when you delete enemies before they can retaliate. Glass Cannon + Executioner: Executioner's 10% increased damage against low-health enemies stacks multiplicatively with Glass Cannon's 15% true damage conversion. Takedowns reset basic ability cooldowns, enabling rapid successive kills. The execute synergy helps you quickly eliminate threats before your capped health becomes a liability in extended teamfights. Glass Cannon + Thread the Needle: Thread the Needle's 18% armor and magic penetration ensures your pre-mitigation damage stays high, which directly increases the 15% true damage from Glass Cannon. Since the true damage is calculated before mitigation, penetration makes enemies take more base damage, resulting in larger true damage procs on every hit.

Avoid Glass Cannon + Celestial Body: Glass Cannon sets your health to a fixed 70% threshold that cannot be modified nor exceeded, which completely nullifies the primary benefit of Celestial Body. You gain zero value from the 1500 bonus health, leaving you with only the damage reduction penalty and the health cap restriction, making this an actively detrimental pairing. Avoid Glass Cannon + Goliath: Goliath grants 35% bonus health, but Glass Cannon prevents your health from being modified or exceeding the 70% threshold. The bonus health stat is entirely wasted, and the 15% adaptive force is not enough compensation. Avoid this pairing because the core stat reward becomes functionally useless. Avoid Glass Cannon + Mad Scientist: Mad Scientist can roll 20% bonus health and 40% increased size, but Glass Cannon's unmodifiable health threshold renders that entire roll useless. You have no control over which variant you receive, creating a significant risk of getting a completely wasted stat bonus with no benefit. Avoid Glass Cannon + Tank Engine: Tank Engine grants stacking maximum health increases on champion takedowns, but Glass Cannon's health threshold cannot be modified nor exceeded by any means. Every stack you accumulate provides zero actual survivability benefit, completely wasting the augment's core scaling mechanic and purpose. Avoid Glass Cannon + Dawnbringer's Resolve: Dawnbringer's Resolve heals you for 30% maximum health when dropping below 50% health, but Glass Cannon locks your health at 70% maximum. You can never trigger the below 50% threshold condition, making this augment completely inactive and providing no defensive value whatsoever.

Glass Cannon: Don't take on tanks and supports, negative effect makes you squishier. Don't be too aggressive, very fragile and bursted easily. Don't ignore true damage also benefits from the bonus. In losing games, this rune is less effective, easily focused down.
