well, i didnt check invisibilty sphere, though it was reported as buggy...

also magic circle versus alligment seems to be to short and wont work properly.

i would recommand players to check them before using them. (i wouldnt even, check, and forfeit those spells, too risky to play with your char's "life")

any bugged spells should be reported here, i think, would be more orginized (atleast, the current known spells).

i am not sure, but i think darkfire, and perhaps flame weapon are shorter then hrs/lvl, though it is not written in the mechanics changed section.

it seems like many areas spells (a circle around the caster) are bugged, dms correct me if i'm wrong.

i just saw in another topic that the silence spell bugged as well.

Working on coming up with a fix/change for Invisibility Sphere and Magic Circle vs Alignment.

Darkfire and Flame Weapon are indeed turns/level. The mechanics change post on the forums has been updated to reflect this.

I'm not sure exactly what the bug with Silence is.

it was said on other topic, i just thought to gather the bugged spell, so it would be all spells on one topic rather 5-6 diffrent ones

All of the issues raised here have been addressed.
