Let's see 3 Skills that I am using. Marksman, Critical Chance and The one with the explosive projectiles (don't remember it's real name). My Critical is at 10 (maxed) and Marksman is at 7 or 8. Combined it makes my projectiles do a lot of damage, I think the highest I saw was about 1400 for a critical strike and the creatures literally just explode from the hit
. The explosive projectile is needed for when you get swarmed and it does insane amount of damage to a group especially when it does a critical hit.
I will be playing this game for quite some time, though I am not sure how much as I am also spending time with Tekken 6, Risen, NWN2, Ratchet and Clank, Dragon's Age Origin's Next week. I can tell you that I stopped playing Tekken 6 to go back and play Torchlight last night so IMO it's a very good game. Risen has been put on hold as has NWN2 for Torchlight. As far as my Steam ID you don't need it as it is setup as private so it won't show up even in a search.
