I picked up this helm from the Spiders QA in the Mouldmire (I think).

It is a bit of a confused item, with spell charges but nothing to spend them on. I used the 1/day summon, expecting the helm to dissappear, but it did not.
I kept it for the skills, and discovered on reset the summon was usable again. I used it again, and on reset it is castable yet again. The charges did not go down.
As currently built, it is a 1/reset IV summon, which seems a bit strong, even for high level QA loot.
This happens because this item was marked as plot. If you create an item with a single use property and make it plot, it will recharge upon resting.
Yes. This Class C DM mistake has been fixed for future versions of this item, but please delete any existing versions.
