Combat Dash
Footman’s "First Responder" ability activates only when hostiles are nearby, becoming a Combat Dash.
The Footman will stay closer to other members in its combat group until it gets near enemies. Then, the Footman can dash at the enemy, and chase after them with a speed boost.
It allows for a little bit less micromanaging them, if you don’t want them to run far ahead of the rest of their combat party.
