Just not a fan of vampires. After killing them in every D&D game since the 1st edition rules came out, I just don't like them. Not a fan of the lich style cleric either, but in his case, he's basically a game feature to allow players to revive dead characters if they run out of scrolls (something I've never had to do). Like Asterion, I can deal with him, but just not a fan. Loved the events surrounding getting him though.
You lost me at "he's basically a game feature to allow players to revive dead characters is they run out of scrolls." What do you mean by that?
he's referring to the undead guy that stalks you and rezzes you at camp. the OP was comparing their indifference with the skeleton guy to his feelings of Astarion (i think).
