Invisibility bugged?

[coolAlias]

Each time I cast invisibility, the enemies still head straight for me and start attacking, specifically elementals (both air and water) and the warg-like critters. Are there certain enemies that can detect invisible entities, or some special trick to how invisibility works?

this was the same in Grimrock 1 if you got too close to the enemies for too long or attacked any of them

I found invisibility in Grimrock 1 a bit "hit or miss" and it could "wear off " after 1 minute however a big plus to qualifying your Sorcerer on this spell was that along the way you got Lightning Bolt which is almost as good as "invisibility" itself

by the time you get to "invisibility" the thought of getting your Sorcerer up on Fireballs seems a mountain climb away, so Lightning Bolt is a great bonus, I assume this is the same on LOG2

I was trying to use it to sneak past those dang air elementals, so I wasn't attacking at all, just moving. I'll have to test and see if they only notice me when I get close or not, but they seemed to come straight for me even from far away.

Air and water elementals can see invisible. Most monsters can't.
