Except that you can't even get ice spear damage on gloves?
IIRC spell damage modifiers go only on weapons. Speed goes only on weapons(?). Magic attack goes only on weapons spell books , including the eagle shield, and accessories.
The glove reforge most beneficial for magic is the ice spear explosion range reforge. Level 10+ is sufficient to wreak havoc.
I never mentioned magic attack for gloves did I? I only said it will increase magic damage, which is what rosemary does for ice-related magic.
Please do some research before posting.
And also, the wiki is correct on the reforge, there are people with ice spear damage rosemary gloves.
