Hey folks. So, apparently there is no way to make Nightcrawler viable at low level.
So, I went back to the player I was trying to help, and the next idea he had was to make a Dread Commando, so that he can stomp around in heavy armor and still be sneaky and dish out beatings. This sounds like a great plan. I just have no idea how to make it work decently. So, this is for an ECL 8 game, all books from Wizards that are 3.5 legal are open. Dungeon and Dragon are out. Stats are 11, 13, 16, 16, 18, 18 before stat bumps. Cannot be Evil.
My only real thoughts were to combine Ranger and Rogue to get the skills and make sneaking around worth it. Though I did consider some Ranger/ToB to give him a little oomph.
