Berserker uses Tunnel Vision- assists in any attacks made against targets in his row
Warrior uses Sentinel- auto-attacks anybody moving into his column
Ranger uses Support- will take a free shot at anybody the Berserker attacks
Possible combo / chain reaction! If the Warrior attacks the enemy in the top row (highlighted), the Berserker's Tunnel Vision will trigger an attack, and the Ranger's Support ability will chain off of that. That's 3 attacks for the price of 1!
