Mo NPC

ok, let me explain in detail what's going on here.
There are two All cures in the data. One is the standard kind that can be purchased from Alcaster and drops from Monsters. It can be traded, dropped, bought, sold, etc. The second kind is dropped by monsters in CarnivalPQ, and is consumed when looted. It's never supposed to actually enter your inventory, however if it were obtained in some other way (Quest, purchased, etc.) it could be.

Now, after discussing this in IRC for a moment, Jay (BladeHavoc) suggested that it might be the one from CPQ. Only one way to find out, so I got on to test it.

I purchased 1 All-cure potion from Mo. I then hiked up to the Keep and angered a Crimson Guardian. It used Seal on me.

 Spoiler

I dropped the All-cure and as you can see from my hotkeys, have no more.

 Spoiler

With the all-cure on the ground, I am in a sealed state.

 Spoiler

I loot the All-cure and... I am no longer sealed. It does not enter my inventory, as you can see.


So, what happens is, as long as you do not drop them they will behave like normal all cures. They will heal your ailments if you use them, they can be traded, and sold in shops. However, if you try to drop some, ALL of them will be consumed as soon as they are looted. this could be quite a deadly error in so far as boss fights are concerned.
