But I mostly just wanted to boost my hits.
The revenant is 4e's first undead playable race, but instead of being a race of their own, they are simply a soul stuffed back into a body by the Raven Queen. This can cause a revenant to 'be' any other race, allowing them access to that race's feats, paragon paths, or epic destinies that their previous race had access to. In additon, there is a lot of 'previous race' related feats to help your revenant recover some of his previous identity. I intend to make a formerly half-elf revenant and make him take the revenant feats for half-elf as well as elf and human. No wait, nevermind... its a racial feature, that might not work...but why not try?
