Crusader

For when you need a smoke break between killing and torturing the followers of another religion

First appeared at the tail end of 2nd Edition's run as a Priest subclass. In 3rd Edition, they became a base class.

A crusader is basically a fall-proof paladin. They use Weeaboo Fightan Magics instead of divine power to kill stuff, which may or may not be better than normal. The crusader also has the power to forget that he took damage that turn and beat things to death easier until he realizes that swords hurt the next turn. Balancing this is the fact that they can't really choose the maneuvers they want to use at a given moment; they just get them at random each turn.

Crusader is the only class (except for the Jade Phoenix Mage and Immortal Blade prestige classes) that gets access to the Devoted Spirit school, where everything is based on what alignment extreme you are and if the opponent just happens to not be the same as you. Yep, totally different from a paladin.
