Cost: 3,000
+250 Health
+25% Bullet Resist
+20% Spirit Resist Passive: When you drop below 35% Health, gain a protective barrier that absorbs 500 damage and provides +10% Bullet Resist for 5s (20s cooldown).
The resists are too high dude. It`s basically both T2 armors combined with an extra 750 hp added, ALL in one slot. Get rid of the resists, make it Purge negative effects(including stuns) on activation and it might be good.
