[@Bloodwolf 2] You can only start with one talent, so pick between Sword and Bow. Just a note, having a Talent doesn't mean it's the only weapon you can use, you can use others, but it will simply be suboptimal.

The ability Invisible Hunter is still an issue. There's no stealth system in this RP, so really based on that description, you could technically score a critical hit every time you fight anything besides mages and beasts.

My suggestion would be to make you get an increased chance to critically strike when hiding in any terrain. If you do this, you don't need to have the condition that only mages and beasts can detect you, you can get that bonus so long as you're using terrain.
