Dark Knight changes needed

[Nektulos-Tuor]

Grit:
Lower damage penalty from 20% to 15%.
(Don't see why Paladin's get a better version of this skill.)

Darkside:
Darkside now properly increases damage by 15%.
(17.25% whilst in Grit, or tooltip fixed to actually direct what it does whilst using Tank Stance.)

Blood Weapon:
Make it be able to be used outside of Grit.
