Support tend to add a little bit of everything to the party, some healing there, a little damage here, help the tank mitigate some damage there, stuff like that.

Support classes are
Seekers
Brewers
Scribes

they're your average, everyday citizens helping the fight. brewers like to experiment with brewing up concoctions for anything. scribes are always looking for more knowledge and if they have to fight through hordes of heretics and demons, so be it. seekers on the other hand desperately need this, they are constantly seeking redemption for recently being shunned by most norri cities, their sun worship seen as mockery of the light God.
