Yay ! You levelled up !
Now, at any time, you can replace this by a Feat of your choice.
Even in the middle of the game, it can be done ANY time !
Remember the rules :
- Feats could be :
- General Feats
- Archetypes
- Prowesses
All of those are *Feats*
Two rules : You cannot take a General Feat twice. You can only have *one* Archetype. And you can only start to have Prowesses after you're level 3 or more. Once you are level 3 or more, you can take as many prowesses as you like or even take the same Prowess several times.
