I've noticed that the Will O' Wisp and Lantern Archon summons from the good domain are affected by spells like colour spray (where they are put to sleep) and the affects of poison (e.g. from a poison goblin arrow).

I'm not sure if these are bugs in themselves or if intended. If they are intended, it's just sort of weird how a ball of light could be affected by either of these, however.

The Lantern Archon is an Outsider. The Will o' Wisp is an Aberration, I think. Neither is just a "ball of light."

Ah, gotcha. Thanks.
