Contrastive Core

Contrastive Core
The Contrastive Core is a risk/reward-type passive item which counters weaker enemies, preventing them from slowly whittling you away. In exchange, the holder of the Core will take more damage from powerful attacks. It amplifies great threats, making each encounter with them incredibly dangerous.

Stacking
The Core can be collected up to 3 times on a character, provided you luck out enough to find it this many times. Its effects will be further amplified and its threshold raised as you collect more Cores.
 * 1 Core -[ Resist attacks at or under Above Average (8) 25%, stronger attacks hurt 25% more ]

 * 3 Cores [ Resist attacks at or under High (22) 50%, stronger attacks hurt 50% more               ]
