Term: Feat
A feat is general, universal feature you can select during a Feat Choice during character progression. Some feats alter or add something to your character, while others fundamentally change the way you play
There are two kinds of Feats, Primary Feats and Secondary Feats. Primary Feats are full on bundles that would considered trees in other games, while secondary feats are more niche and much less powerful, but shore up a character's theme.
