Replace it with the following Perk
Shield Master
Grants “Beat Back” Skill
Fatigue Cost: 20
Type: Activate then Reactive
Activate this skill to attempt to deflect an attacker engaging you (moving into a hex adjacent to you) or missing you with an attack.
Hit foes are knocked back 1 space, suffer 10 fatigue and lose 1 AP.
This skill remains active until the start of your next turn, or until you are knocked back or stunned.
This skill could have some synergy with riposte and spear-wall.
Of course orcs would have this to ruin your day as well.
