... You can feed the slime? How? :o
EDIT: Figured it out. Huh, either I crit failed on reading comprehension a while back or the game did not explain at all that this mechanic existed. So I've gotten him to learn Protect I by feeding him Big Bones, but none of the other items I've tried have given him skills. What else besides Big Bones gives him useful abilities?
It's not about what you feed it, rather the Slime learns abilities at Lvl 2 and... 7, I think? My preferred strategy is to work primarily on MATK+HP via Living Hearts, Goblin Teeth, etc, (and whatever else is high value, though Avian Feathers can be a tough pick as Aura's AGI is a rather important stat). Also, 1 Mutant Spore will help with the Morph spells if you don't want to spend money on Mana Stones.
Once you get it later on, the Fire/Wind Slime morphs are arguably the best types to have it morphed into overall.
