Oryol's Starting Traits

Trait Name: Hard Shell
Trait Tier: C
Trait Requirement: Being a magician.
Trait Description:

This magician is what a fistfighter would refer to as a "hard shell". Their borg is exceptionally resistant, either from training or good genes. A stronger borg takes longer to reform after being damaged, leaving the user defenseless.

Trait Effect: The user's borg may defend them from an additional tier of damage.
Drawbacks: The user's borg takes an additional turn to reform itself after being broken.

The drawback you have isn't really significant enough to justify the boon this trait brings you. A single post added to your cool down isn't really that much of a disadvantage. Especially when the nature of a magician's capabilities means breaking their borg is already a difficult hurdle as they can fly away from most attacks and magic is versatile enough to clash with basically anything.

Since an increase in tier is a doubling of power, either change this to a doubling of the cool down(6 posts) or think of another trait. Your borgs effectiveness would also still be capped at the max of Omega meaning at end game this will ultimately become a disadvantage.
