Funny you mention that, I have a character currently playing as a
4th Level Rogue (Knife Master/Scout)
1st Level Gunslinger (Bolt Ace)
1st Level Evangelist of Pharasma
He plans on following that path out to lvl 15 with her to get the holy form from 10th level Evangelist.
Hes part of my Carrion's Crown group. The Bolt ace is due to a crossbow marksmen (Dreamscarred 3rd party) character who died previously in the campaign. Cella (the rogue) took up his crossbow and multiclassed to carry on his legacy.
