I have trouble understanding why it is such a big deal that it has only 1 Int, beyond "the rules say a PC shouldn't play something below 3 int". Isn't the goal of the thread to allow for play things that aren't allowed by the rules? I mean, we have rated things without a mouth, things that cannot move by themselves, things that are literally a swarm of smaller things, things that suck the spells out of their teammates, and things that litterally kill themselves when they try to eat anything that wasn't injected with evil, but something that has the intelligence of a sheep should be disqualified immediately? Why should it be unplayable?
Also, Element-infused (Fire), from the
Advanced Bestiary
could work (not sure if 3rd party is counted but heh, at least it is a way).
