Barrier is a temporary damage shield in Diablo 4. Here's how it works.

What is Barrier
Barrier absorbs damage before your HP. It decays over time if not consumed.
How Barrier Works
- Decay: Barrier decreases by 1/3 every 0.5 seconds
- Cap: Barrier can't exceed Max HP
- Effect: Damage absorbed first, then HP
How to Get Barrier
- Sorcerer: Ice Armor, Energize aspect
- Barbarian: Challenging Shout with Iron Blood aspect
- Necromancer: Disobedience gem
