S'been a while since I've won with a rogue... any rogue. I think the only time I've actually done it was with one that basically used wands as a godhammer, thanks to good ol'freakishly high skill points. A high use magic roll on some wands can do a
lot of damage. We're talking one-shot young adult dragon level stuff here. Though it may have been the bard that did that... or both. Wands got some kick to 'em.
Anyway, if we're talking winning combinations... the two most ridiculously powerful builds I've ran have been a priest (3, pain/passion/strength, of Zurvash)/ barb (8 ) -- once with a drow, once with an orc -- which did ridiculous things like punch greater demons to death while grappled and hanging off the ceiling, and a borderline gamebreaking freakish-int thaum-specialist mage/loremaster, who got her int up over forty(!) and started turning adult dragons into rats. At that point, the whole game is basically your bitch (and I was there before hitting level 11
).
Casters in general are just completely overpowering in Incursion, somewhat unsurprising considering one of its heaviest influences. I once did a minimum buff run with a mage (and DitL'd it,
here), beat a bloody
challenge (edit: wait, it was a standard run. Eh.) game with nothing but detect monsters and floating disc as sustained spells. Druids and mages are roughly tied for 'biggest badasses in Incursion', with priests and rangers coming in around second. The rest are bloody good (except maybe monks, who have a helluva time getting off the ground), but those four are simply top tier. Crazy stuff goes on wit'max level incursion characters
