-After spell and item effects are applied,resistance is capped to a max of 100%

-Piercing is then appplied.This means any unit attacked by piercing ability will at most have 90% resistance.

e.g

werebears attacking brooched leviathans.

Werebears have melee type attack

leviathans have 95% melee resistance

brooch adds 50% melee resistance for a total of 145% melee resistance

resistance is then capped at 100%

Piercing ability applies which reduces final resistance to 90%.
