Base Class Alteration: Fighter
Scent of Blood, Taste of Blood, Improved Weapon
My goal here is to alter the abilities of base classes, slightly, so that the decisions of which moves to take is less easy. For a fighter, for example, Scent of Blood is strictly inferior to Merciless, and I think when you have a situation where no character would ever choose ability a before ability b, it’s a problem.
If there are resources that already do this, then I’d love to be pointed toward them. For now, here is what I’ve come up with:
Scent of Blood
When you hack and slash an enemy, take +1 forward against your attacker. Your next attack against them deals +1d6 damage.
Taste of Blood
Replaces: Scent of Blood
When you hack and slash an enemy, take +1 forward against your attacker. Your next attack against them deals +1d10 damage.
Choose two extra enhancements for your signature weapon
The justification for the last one is that an extra enhancement is roughly equal in value to a 1 damage increase, which is again, strictly inferior to Merciless.
