Getting wishes from an Efreeti

[Crake]

I mean, it's not stated in the rules whatsoever. The FAQ has an answer on it that mentions the lack of rules for it, but the closest the rules ever get to stating how it works is "In all other ways, a spell-like ability functions just like a spell." However, in this particular area that's as good as not saying anything at all.

I definitely recall reading it very explicitly out to my players at the table and us unanimously agreeing it was too much bookkeeping. Ill continue to try and find the source, so I guess watch this space for now?

Why prepare or learn Wish when you can just use shapechange with basically 0 cost?

Assuming you’re referring to zodar, because theyre limited to 1/year clearly, assuming a) they even exist in setting, and b) you even know about such an esoteric creature, and c) the DM doesnt deem them to be rare and unique creatures such that they arent a valid target to be shapechanged into.
