The better place to put this post is in the ideas forum, not the help forum, though I can understand your mistake.
How about:
Advanced set, requires triggering.
Shield slam
Single Target damage
The footman slams his shield into an enemy, causing the enemy to be knocked back and damaged for (50/100/150) damage.
Wounding Stab
Single target slow
The footman stabs a unit in a pressure point, dealing 75 damage and causing it to move and attack at (75/50/25)% speed.
Rations
Passive
The footman always carries a pouch of rations with him, so that when he reaches (10/15/20)% health, he begins regenerating 50% of his health back.
Ultimate: Defend
Toggle
The footman enters a defensive stance, recieving 50% less damage while moving at 25% speed. If the footman shield slams while defending, he will deal extra damage.
Begginer set/no triggers
War rations - active heal over time
Shield Slam - short ranged storm bolt
Endurance aura - tauren chief
War march - Stampede. Turn kodo into footmen
