I realize its entirely possible that no-one knows the answers to these questions yet, but seeing as how Lex has answered a great many seemingly un-knowable questions through careful analysis of the video footage available I thought I would ask.
1.Is it possible to make unarmed attacks from the back row using "Reach Attack"
-This could be a lot of fun just to uber specialize a skull carrying unarmed combat minotaur for max damage.
2.Are characters wielding shields considered "unarmed" what about Dual wielding shields?
-This was an option in dungeons of dredmor, you could wield a shield in each hand, and still fight "unarmed", between the defense from two shields, the bonuses for "dual wielding" and the bonuses for unarmed you were an unstoppable if somewhat low damage killing machine that was virtually impossible to strike.
3. Is the evasion stat a percentage?
-Seems Low enough... and that would make optimization alot easier than if it uses some complicated formula.
