The Boldblade Truffle (Magic Weapon CL2 Single Use) doesn't work on the hak weapons.
Are you sure? I doubt this very much, unless all magic weapon charges/spells don't work on hak weapons.
I cannot confirm this.
I can confirm that poisons used on hak weapons do NOT work.
I can confirm that spells cast by a spellcaster on hak weapons work
Can confirm that spells cast from items ONLY do not effect Hak weapons. Spells cast by players still work normally
Yeah, I am not sure what is up with this. It's puzzling me. I'm investigating but I have no ETA on the issue.
It seems that they do work, actually.
The issue is, if you target the spell to the weapon itself in inventory, it won't. If you target the item on your character, it will work and cast it on the weapon you have equipped.
It is probably a script check somewhere, and I'll hope to fix it when I got time to investigate deeper, but for now just target your character, not the inventory.
