but I can't seem to find one that has good stealth so far.Any recommendations?
That is one of my many
beefs with exp/levels, at least with the traditional unquestioned exp-for-killing-things bummed from D&D games.
A good stealth player fails to level up.
I really like Sil's concession of half xp for studying monsters without killing them, and xpxp sorta works but I think Brogue's loot-based stat gains are more visceral.
