[Bug Fix Required] As posted in another thread, Monster/Denizen Ogres and Earth Elementals can't Hurl Boulders because they have a spell, not an ability, and they have no mana.

I was just playing in .990, and this worked fine... 

I use an Earth Elemental in .992 and Hurl Boulder works just fine. Maybe your .xmls are messed up?

I mean when the Earth Elementals or Ogres are on the Monsters and Ruffians team or the Denizens of the Wildlands team, they never use Hurl Boulder because it requires mana.  I'm using default XML.

You can use it because you have the 6 mana required.  The monster AI can't use it because it has no mana.  The whole point of giving these creatures hurl boulder was to help control kiting. 

I looked at the xml of these monsters and it follows the same pattern as say the darkling shaman for code. So, maybe the AI hasn't been hooked-up to use these boulders yet?

You're probably right.

Fixed, thanks.

Just out of interest, what was the problem - that the spell cost mana, or because it wasn't properly hooked up for monsters to use?

It was a problem with the xml A file I didn't check had hurlboulder when it should have been hurlboulder_ability. Found it after he said he fixed it... there are so many different xml files to look through no wonder these errors slip through
