It's been forever since I played Dark Sun, but didn't every non-psionic character get a free psionic power? They could easily handle that by giving everyone the (presumed) PHB3 feat for a minor psionic power.I highly doubt we would see the random part, but a feat to allow someone minor psionic power does not seem out of line.
If they bring back inferior bone weapons, etc., it would weaken characters with weapon-based powers. They could apply comparable preserver limitations to all arcane implement-based powers (unless you take defiler feats?). I'm sure they could come up with something else for divine and primal implement powers, but it seems like it would get tricky to balance if they went down that path.I'll be interested to see if they actually have the weapons and armor be inferior to the metal ones in the base game. I hope they just don't keept he same stats for everything and just call it something different. I'd also like to see the weapon breakage rules. But that seems like a long shot.
