Glover Mallory sold me a Nordic Warhammer of Extreme Chaos, so it seems the enchantment is available through stores/his store (and probably random loot too I guess?) which means that it isn't a unique enchantment to the weapon.

I don't know how many people know this, but I saw a few people were not sure whether they wanted the enchantment or wanted the "unique" weapon, so I thought I'd let everyone know just incase they were having a hard time deciding

Aye, I have seen more then a few weapons with this enchantment now. But to me, that cudgel looked good in the inventory and on the wall but held in hand, it was absolutely horrible looking.

I had no qualms about disenchanting it and using said spell on my Stahlrim greatsword. When I enchanted that, it actually ended up doing the regular 50% of all three elements but for 90 points of damage, instead of 50. No potions of enchantment used either, just level 100 enchanting and 2 points into the very first enchanting perk.

Thanks, Moxie! I wanted that enchantment to put on a crossbow, which is Verena's favorite weapon. Do you know if any other blacksmiths in Skyrim sell weapons with this enchantment?

Thanks for telling us. Was considering disenchanting the cudgel, but I didn't want to. But now I don't need to, yay.

Can anyone answer this question?

My sword is enchanted with 29 fire damage and 29 frost.

If I'm reading the chaos thing right, its a 50 percent chance to do fire 25-frost 25-AND shock 25? (25 of each one, at the same time?)

I haven't seen any other people selling the enchantment. I hang out at the skaal blacksmith to stock up on stal ore and he often sells at least one weapon with the chaos enchant on it so you don't really need anyone else. He also usually is selling the ancient Nordic pickaxe as well as the ore so hes your best bet.

How often do the blacksmiths tend to sell the chaos weapons?

FOR THE EMPIRE!!!

It's random, but I have bought 2 weapons from Glover Mallory that had it, just keep checking with him. Two are on weapons racks back in Heljarchen Hall, they look awesome! The third I disenchanted and put on a stalhrim greatsword as well. Wow!
