I agree with c3p, start off with few just to see how it feels. And once the characters arrive at a point where they could use a full team of six, see how we want to do it then. 

Also, I decided on a concept. Gonna rework a character from an old RP I never got to use, which I think will fit in well. Now I'm writing the character sheet! 

Two quick questions though: our characters are intended to travel together around the region, right? Also, since exploration is handled in a certain way, would items like pure incense, repels, etc. effectively do nothing mechanically? I was thinking about taking a cleanse tag for the held item for aesthetic/RP purposes.
