The Greater Dragonmark of Finding gives Treasure Finding, which has a chance based on your Charisma, to boost the loot level in the chest by 1. I was interested in taking a Dragonmark next life as a Human because they made it so that you need to spend points in Enhancements rather than feats, making it easier to access.
But how much Charisma do you need to use it effectively?
I was thinking about using it with a Rogue Mechanic Enhancement line to make a "Treasure Hunter" type of a build. Wondering if around 12-14 Charisma might be enough to start out with.
