The navi is a playable race specific to Slash'EM Extended. They can be any role and alignment, and they start the game wearing a pair of wedged sandals which, for a navi only, increase kicking damage when worn. A navi also does bonus damage with all weapons that use the spear skill. Their maximum stats are as follows:
If they are a role that is proficient with spears, navi should try to use spear-class weapons. They can also be multishot in Slash'EM Extended, so a stack of them might be used for throwing. Especially early on, the navi may want to use the kick command often to deal extra damage to monsters. This advantage will be even more useful to a martial arts fighter, e.g. a monk.
Eating humans is considered cannibalism for navi, and therefore a bad idea.
