You need to add a new source to get Scroll for Gloves for ATT that gives weapon attack +3. It was only available from Spindle.

Dw I'v got a plan ;) your not gonna like it tho hehe, but its balanced.

Spindle is back in Omega Sector with his original lines, and his old shop stays removed. Note: the original game data has no quests for Spindle at all (he only talks about the card game), so there were none to restore. The Gloves for ATT scrolls drop from Mushmom, Zombie Mushmom, Dark Stone Golem and more, and are also sold through Town Reputation in Kerning City.
