So I've recently started playing this awesome game again (I played it before, but never got around to finishing it). I've now once again arrived in the Ice Rift, but I'm facing a rather annoying issue: for some reason I can't remove the level drain on one of my knights.
I have the Level-7 Remove Negative Levels spell for my Cleric, the problem is that I simply can't use it, because it's constantly crossed out on my spell screen.
I'm probably overlooking something pretty huge here, but I can't figure it out. Why can't I cast the spell? What are the conditions for casting it?
Thanks in advance!
P.S.: In case you were wondering, yes, I'm 100% sure the level drain is not being caused by a piece of equipment.
