This helmet has summon monster 2 once per day on it. It summons a spider instead of a normal cave bat because the helmet is themed. However, I didn't like the color of this helmet and dyed it. The Summon monster 2 now only summons normal cave bats and not spiders. Character name is Xanian Urthadar. Thanks in advance for fixing this bug. <3
Whenever you dye an item with a summoning theme on it you will see this result. You will most likely want to seek out a DM in game and simply have the item replaced with the correct charges on it(assuming it has any) and avoid coloring it again.
Usually these thematic items with special summons are flagged as plot and cannot be dyed.
Ah, that would explain a lot. I'll keep that in mind for any future items I find. Thanks. =)
