Right ... lets get going then:
First, the area is shed in darkness from two castings, one by Zouhlnor, the other by Zhadristan. Essentially, the beholder needs to come pretty close to the path to see anyone of you, unless ... .
Everyone seeks cover behind some object, apart from the skeleton warrior summoned by Jhalashar. The sound of the bard's song lingers on as well. A few of you have been "enspelled" by a sound out of Jhalashar's second horn.
By chara ...
Iira has power stored in his chain, sought cover and waits.
Zhadristan cast a spell on himself, plus darkness while drawing a thunderstone
Zouhlnor cast darkness and psi-powerd himself up (he's still large, methinks)
Keth sought cover and cast a spell on herself
Narzen sought cover, loaded his x-bow and prepares components.
I know of Geirildin, Nata'al, and Talice, of course.
Any late additions? Wait till German Noon before I get on.
