I dunno where I'd post such a curious question, so I'm just gonna post it here. And hopefully a mod or someone can move it to the right place if this isn't deemed appropriate.

So, I'm playing Divinity II: Ego Draconis and I just recieved the "Ultimate Good Warhammer" and I added a few enchantments to it. It has the same enchantments as the weapon I'm using now, and overall it has a higher normal minimum damage, but when I equip it over the second weapon, it shows a lower minimum damage. It's not a huge deal, but when I calculate it all out, it just doesn't add up.... :-/ Can someone tell me how the actual damage is calculated? Here are the stats of each weapon followed by my stats while each is equipped (keep in mind, I use dual-wielded weapons and have my dual wielding skill at level 10 for a 19% bonus to primary hand and 20% bonus to off-hand [which also doesn't make sense to me >_<]):
