The Complete Psionic has a new Psion character build/power that's focused on just bending reality in strange ways. They can summon an invisible space-occupying force, create stuff from the adventurer's tool kit, and have a lot of fun warpy-bendy powers. They summon ectoplasm, which I'd bet on a few days before the book came out and I'm pleased to say that if someone had bet against me I'd have a dollar or something. And make walls, obstacles, conjurations. Not terribly thematically on-topic for a mind-mage, but good stuff! I'm actually interested in this one, which really hasn't been the case for a lot of psychic classes--at least unless I'm trying to fill a party void.
Dark Sun has a new Shaman build that I'm interested in playing, but I think I'm going to hold off for now and experiment with the bear shaman instead. Whines's intermittent game has a serious striker bent to the party, and we're a little low on defenders right now, so I need to have a "hold that line, please!" character in place. It's three ranged strikers, one melee striker/defender (two-handed weapon fighter) and one striker/leader (cat-shaman, my character). Need to work on safely melee-buffing the fighter.
