I have question about the Staff of Nature's Wrath. My druid was using it and it can cast Entangle and Flame Strike. I used it for a while but then all of a sudden my druid wouldn't cast Flame Strike. Entange still works but when I make her cast the Flame Strike she just stands there and does absolutely nothing. Is there a limit to how many of these spells you can cast or something??

Yes, there's a limit. You can cast ten each of the two spells. TANSTAAFL.

That bites goblin ass. It didn't even say anything like that when I looked at the item description. What a gyp

Those who have played d&d games before should already know that most items
like staves, wands, and some rings are charged items. However, it should at least tell you the number of charges left. I mostly keep them for use in emergencies only.
