Just learned of this site today.  It’s like Wowhead but for Torchlight 2. Has all game items, calculators, spell info and databases.  A definite go to site for TL2.  

Been playing TL2 for a bit and so far I can’t complain. Runic Games network is down atm so can’t do any co-op games but I can still do single player
