I just noticed that Bittercut does Corrode/Slash damage instead of Slash/Corrode. Why haven't I noticed that before? So it really should benefit from Corrosive Lash and Spirit of Decay.

Many thanks for your various data on this subject! As Braven said, I also get the feeling that some of these effects may be unintended by Obsidian.

Do I understand this correctly that my weapon's bonuses are applied to my spells when I cast them? Like when I have a flail as my primary weapon and cast a spell, the 30% graze to hit also apply to my spell?

So are there any items, abilities or spells which reduce a foe's corrode or burn DR without touching slash/crush DR?

Hey wait, if I use Forgemaster's Glove and Durance's Staff, the game should use the staff's fire damage in most cases! So here I can use Scion of Flame to further increase the burn damage. This would also fit for my new paladin and Flames of Devotion.

Thank you for the detailed explanation! I wouldn't have guessed that the game will strictly choose the first damage type if the DR of both weapon is identical, without concerning the most damage output. This is quite sad, so I will forget my idea. And you guessed correct, I also had thought of this idea with Durance's Staff. So this will only work with Stormcaller because of the shock DR. So I conclude that those skills like Spirit of Decay are more intended for spells and abilities which do the corresponding damage types.

I want to improve my understanding of the game mechanics. Here is my thought of Bittercut, please correct me if I'm wrong: If my character is using Bittercut and I add a Corrosive Lash to it while I'm also using Spirit of Decay, what is the outcome against enemies which have the same slash and corrode DR? I would assume that against these enemies the weapon will always use the corrode damage because Spirit of Decay benefits the corrode damage of Bittercut, but not the slash damage. Is this correct?
