The Tavern

Has anyone considered this combination of spells before: Sticks to Snakes + Teleport Other + Inner Flame?
Every time you enter a new floor, teleport some fire-filled snakes around. Since you're limited by the amount of arrows you have you can do it only for dangerous levels. As an option with Kiku you can acquire corpses and teleport skeletons. (You can't fill with fire usual summoned monsters.)
Have fun!

Does this work with standard summons like rats and hounds?

No, those can't be inner flamed. You need to use snakes or derived undead.

I was under the impression that allies do not fight enemies out of your LOS. An ally at edge of LOS will stand stupid and get whaled on by an enemy just around a corner--is that correct (anymore, or ever)?

Does that acutally work? Seems like its a great way to wake the entire level up.

Won't the flame clouds immediately dissipate because they're out of LoS?

It's correct for true summons. For some reason, Sticks to Snakes is exempt from these rules, however.
