Guard Barrier
Grants you Barrier equal to 5% of your Max Health Total for 5 seconds when you apply negative effects to enemy units.
Effects & keywords
Barrier (on user): Blocks damage to the head/body, consuming stacks equal to the damage blocked.
How the math works
Barrier = 5% of this unit's Max Health Total, lasting 5s.
When it runs: Runs after every effect application in the fight. It continues only when this unit applied the effect, the application was not missed or resisted, the target belongs to the Enemy faction, and the effect is marked as a debuff (Negative) in the effect table.
What it applies to: One Barrier per debuff application per enemy. A skill that puts two debuffs on five enemies makes ten Barriers. Taunt is marked as a debuff in the effect table, so a taunt landed on an enemy triggers it too.
Things the tooltip does not tell you
- Debuffs that land on yourself or on allies never trigger it, even if you applied them.
- A debuff the enemy is immune to, or one that misses, does not trigger it.
- Fortified raises each of these Barriers, because it boosts every Barrier that lands on its holder.
