Opportunist All enemies and players will receive this trait
Pet Pal Pet pal gives players a pet companion. The companion will be 1/2 their level after 1. Only 1 person per group
Summoners only 1 per group.
Undead no undead characters
resting there will not be bedrolls, Resting will be handled more like in d&d. Tell the GM when you would like to rest. This will impack gameplay and how long quest / dungeons take.
race non humans may be looked down on by some in the major cities run by the magisters
