Crutchable? ![Razz :P](https://forum.c-rpg.net/Smileys/default/icon_razz.gif)
Relying on it.
Example:
plate knight and ninja peasant fight.
ninja gets 11 hits in with his pitchfork, while knight has 0.
Finally he gets a hit in, and kills the peasant in 1 hit.
IN this case you can say the knight is a armour crutcher, since if he didn't he'd be dead by now.
