I am LOOKING for a wraith assassin build. I just think it would be fun to stealth as a wraith and then assassinate out of the shadow... floating from kill to kill...
The PM tree has a few boosts to hp, incorp, and sneak... to sortof make up for the 3 level loss. You wouldn't have much self-healing... unless it was a halfling with dragonmarks and you force yourself to pop out of undead form to self-heal... and then pop back in. Having a skelly pet to draw aggro could also help... and the wiz lvls could use some of the Charm features of your posted build. Has anyone seen a build like this I could use as an example?
