I would merely suggest raising the bat's DC up by 3 or so. Right now, being lvl 5, it is by far the worse as the DC on its mojo is so low and that is the only thing that makes it even viable over the other companions. I know not all are made to be awesome but the others all seem to have their good perks while this one is just barely feasible as a companion. Now if they are meant to be like this because it exponentially becomes very good well then ignore.
Bat DC
I think he is referring to the druid's bat companions screech attack (Which is like makes opponents fear) and shrieker attack (Which is similar to doom)
Yes, I suppose I did not clarify. I mean all the bat companion's spells. The dms know which they are and I will not specify them all so that there remains a couple of surprises for all those not on the druids side :twisted: .
