In Taoism, Taoist priests believe that all evil things in the world are caused by evil ghosts. The Taoist priests summon benevolent ghosts to combat these.
I would like to make a build around this. However, there are no ways to have more than two ghosts, unlike the zombie exploits. And precious few ghostlike spells. I guess I'm just looking for suggestions.
Tl;dr-I want to make a ghost summoner class. Any suggestions?
