I'm not sure if there's a direct counterpart to this in PnP, and I don't really care, but this is one illusion spell I've always wanted to have: something that works like the cleric spell Sanctuary, with the usual Will Save associated with illusions. 1 Turn/Level, applying the effect and making you look like a rock, tree or something else appropriate. If you move, you break the effect. (Alternately, you're rendered immobile but you can dispel the spell with a chat command.)
I'm not sure if Sanctuary turns you invisible like GS. In that case, it'd be a bit more complicated, dropping a PLC where you stand.
