Sorry to stall the thread again. I'll ask here, and then I can actually try to work out an action or two.
1) What height is the ceiling in here? Do I have five feet to jump up?
2) How far away are the guards?
3) By their not noticing me, do I have a surprise round, or just being hidden until I break cover?
4) If I do have a surprise round, can I alter my essentia distribution as well as taking a standard action?
