Spider Mines (15/15): Your primary spammable DPS. They track enemies and deal significant fire damage. High levels reduce their cooldown drastically.
Gun Bot (15/15): A powerful stationary turret with high physical damage. At max rank, it has almost 100% uptime.
Sledgebot (15/15): Your heavy hitter. It has a high health pool, deals massive melee damage, and can stun enemies.
Immobilization Copter (15/15): A massive debuff tool that slows enemy movement, attack speed, and casting speed.
Forcefield (15/15): The best defensive skill in the game. It absorbs a huge amount of damage for you and your minions.
