I firmly believe that this domain should cause Acid damage upon casting darkfire.
Fire doesn't seem to fit this domain at all.
nah... oil damage would be enough.
:P
Summon themes have nothing to do with conjurations. Especially when you consider that flame weapon is an evocation spell. Honestly wizards should be able to toggle the element of their flame weapon spell.
DRD, the point of this post is that the OOZE DOMAIN, not the Ooze THEME, did not change the cleric darkfire to ACID dmg.
Sea Caves changes the Darkfire to Cold
Storm to Electricity
Air to Electricity
Earth to Acid, Caverns to Acid
etc...
Ooze should change it to acid as well.
