So the shortsword...
Is it between Zemryn and Gimlak? Faenala and Thorin are mystics, and Gob isn't there yet.
I would lean towards Zemryn, only because Gimlak already does a good amount of damage with his fists. Almost as much as a short sword.
To my knowledge, Variant Human is the only way to get a feat at level 1. However, I’ve never seen having a feat at first level to be that much of a problem. There are a few feats that make sense at first level. Magic Initiate, Prodigy, maybe a few others. It gives a little flexibility to one’s character.
I'm starting the lean the same way. As long as it makes sense for the character and background, then all good. Gimlak being a folk hero must have some signature moves![]()
