So I use Grasp of the Grave (709) quite often, usually right after casting maelstrom to keep most critters from running out of the room while it builds. The problem i'm having is the mana cost, and if i'm low on mana.. I tend to risk frying my nerves. Sometimes when I cast, it only costs 3-4 mana.. other times it can range from 9-14 mana. There is nothing about this on the GSWiki, at least that I could hunt down. iS there something i'm missing? for a spell that seems like it should cost 9 every cast, it seems to fluctuate too often and I tense up each cast, hoping i'm not gonna fry my nerves out again. Any help with this would be great. Thanks.
