According to Petopia (and a loooot of Googling) I am fairly convinced that Core Hounds should come with the “Obsidian Skin” and “Molten Hide” abilities (amongst others). However, upon taming “Gomegaz” (the Yellow Core Hound in Blasted Lands) @ level 15, it doesn’t seem to have those abilities (can’t see them in the Spell Book), nor does it seem to use any of them in any trial fight scenario that I’ve put it through.
And I have Googled my *ss off about it, but I can’t find any certain conditions for those two abilities to become available. Maybe I have to reach a certain level for those abilities to activate (even though it doesn’t say so ANYWHERE)?? If someone could shed some light on this, I would be very grateful!
