Topaz Brooch
Common item (white)
Every kill gives you a layer of temporary health (15) that wears off. Each extra brooch adds 15.
Game text: «Gain a temporary barrier on kill for 15 health (+15 per stack).»
Stacking: Each copy adds the same, no cap.
Watch out: The barrier decays on its own (3.33% of your health per second) and the brooch gives a fixed amount: with high health it falls off, and Aegis beats it once you heal well.
