Acid dart (Sp)

[Atalius]

When wild shaped can a druid use the Acid Dart ability granted by the Cave subdomain?

I don't see why not. It's a spell-like ability with no components and no description indicating the need for pointing a finger or anything. It isn't form-dependent. Go for it.

Yeah, nearly always class abilities are usable while polymorphed. The rare cases where they are not is when something about the ability depends on something particular about your form. The way the polymorph stuff reads, along with FAQs make it sound like it should only be things that depend on the actual native form you were; in other words, only your species could actually gain the class ability. Truly very, very few abilities meet that definition; I can't even think of any off-hand.
