Undeath is a pretty fun well to dip into, so long as you aren't actually drinking from it.
The thing is, it's a tricky and contentious brand of magic. The last couple of articles might have gotten you interested, but of course, it's not like just anyone can cast animate dead. (Sorry sword-swingers, before you get too excited, I'm not about to reveal a way for you to reanimate undead minions.) Animate dead is only for wizards and clerics, and worse still, the moral implications of even using such a spell are... suspect, at best. Being a heroic fantasy game, D&D characters are generally going to be good, and it can be hard to justify reanimating corpses with negative energy as a result. The problem is, naughty necromancers don't get any love from Santa come Christmastime. So how do capital-G-Good characters get in on the fun? And in the spirit of the season, can't rangers, druids and paladins also get a present while we're at it?
