well, the spell is just too short, prevent from any useful use of it. i wouldnt say a thing about it, and accept it, but it is not mentioned in the mechanics changed page, in the site... its suppose to be hour/lvl buts its like round/lvl

What may have happened is that you took and area or waypoint transition. Those circle spells really bug up all the time, and in my experience with that one, those transitions take away the visual effect. Sometimes you still get the bonuses, and sometimes the visual effect will come back later if you transition again, but it's still a quirky problem. Most (all?) area circle spells have problems.

Whoa, both of the aura spells bug-reported in one day!

Magic Circle vs Alignment and Invis Sphere are both glitchy in NWN multiplayer, as far as I am aware. Fixes would be greatly appreciated, if you know of them.

thank you, i thought, actually, that this spell has bugs in the single player as well :P

though its allways good to report the bugs, more for the other players, rather to expect a fix. (perhas right it somewhere?, some sticky to: bugged spells would be appreciated)
