Ninja Costume calculates block removal incorrectly when modified.
"Removes 100% of all block on self" probably should not be modified by things such as haste, knight's shield, or iron helmets.
The game calculates that 100% removal based on an invisible -1 base number, but adding armor via the above methods modifies that percentage multiplier. Just adding two armor points makes the Ninja Costume add 100% block instead of removing it, which contradicts the text.
