Hmmm.....'about' 15? Because even though 15 CHA is the minimum when rolling a Druid, I definitely wouldn't consider CHA to be their primary requisite. So if your Druid's WIS was really 15, then Druids ain't worth poopie unless you cheat in order to allow the Dual. But if you're not sure the WIS was at least 15, Aelia, I'm afraid Telchar and I are going to have to ask you to do it again
with all 18's this time, just to make SURE it's impossible.
Because I hate Multiclassed Fighters, that's why.
I think it's time for a new sig.
