The following magic mods add their own materials for weaponry:

Bewitchment
Nature's Aura
Roots 3
Astral Sorcery
Blood Magic
PSI
Abyssalcraft
Vampirism
Evilcraft

There are some others I can think of, but they are handled by other addons already

Hi,

• I had thought about adding support for Blood Magic and even looked into the code to do it... I'll have to see if it's still feasible to do.
• I'll have to take a look into Bewitchment and Nature's Aura as I haven't played with them yet. I didn't even know Roots 3 was a thing either.
• As far as Astral Sorcery goes, I would have to see how feasible it would be to add the Crystal growth and dulling mechanics to my weapons before I can say for certain.
• I'm not sure if I would be able to add Psimetal weapons from Psi, but I'll take a look into it...
• Abyssalcraft should be straightforward to add provided there are no special behaviours for weapons in that mod.
• I'm not entirely sure what materials exist in Vampirism, apart from Silver, that exist in that mod. I'll have to look into that as well.
• I've not played with EvilCraft for a very long time, so I've forgotten what that mod even contains.

Thanks for the suggestions.
