How about we do that but allow Shade's suggestion: summoning them in air and lighting them? Since they're not aquatic, they probably don't have to be summoned in the water.![]()
Ok, I don't even need the summoning bit if we write in that they can burn like alchemists fire. I guess really like a flask of oil, taking a full round action to light.
I now have this mental image of some PCs fighting trolls or ogre magi, running out of fire weapons but recognizing all the "fish" swimming around near them.![]()
Ok, then, just take Cleon's basic stats and add
Flammable (Ex): A black burner (alive or dead for no more than 1 week?) burns easily due to the special oils in its flesh. If lit carefully, a black burner body corpse can be kept burning as a small fire for up to X hours. If lit quickly, a live or dead black burner can be lit and thrown as a splash weapon as a full-round action, following the rules for alchemist's fire otherwise.
