Basic Info: The burrower is a mildly blind dwarf miner that has the ability to burrow and move through the ground undetected by defenses. When it resurfaces to attack it then becomes targetable but head back underground to move throught the battle field.
Strengths: Untargetable to defenses when moving, therefore useful for sneak attacks
Weaknesses:
needs to resurface to attack
becomes vulnerable to attack when not in motion
it not very 'tanky'
relatively slow
Additional info: They joined the battle as miners from the base's gold mines who wanted to assist in the fight. They love gold and solid objects such as walls.
