After all these years I still did not completely understand how offhand damage works (well, how it is exactly calculated), when asking ingame I get several different answers.
Weapon damage of the weapon itself seems to be not that important when it comes to offhand damage, for example, the T2 axe as an offhand weapon doesn’t increase your damage as much as a Falchion of the Blue East does, a blue crafting weapon, 100 combat rating gems in the slots for a total of 364 combat rating on the weapon (T2 axe got 233 CR and 32 strenght). With the blue crafting weapon I got 1 DPS more than with the T2 axe as offhand weapon (even though the weapon DPS itself is 14 points lower when looking at the weapon stats).
The armor builder of AoC>TV sadly doesn’t calculate a weapon as offhand weapon if you put one in there, so what’s a reliable way to calculate the damage you get for a weapon in the offhand slot?
Right now my barb is using the T3 axe and T2 axe, in May I wanted to claim the weapon scroll on that char so I would get the T6 swords, however, if I look at the combat rating of the T6 offhand weapon (Blade of the Manic Haze) it has far lower CR than the T3 axe (but higher weapon DPS), would the T3 axe be a better choice as an offhand weapon than the T6 weapon?
The actual DPS of the T6 weapon itself is 9 points higher but the total CR on it is 84 lower (T3 = 364 CR, T6 = 280 CR).
