Zato the Blind Staff Master

Zato costs 40 gold and is the second hero you unlock. His first two abilities raise Chesterson and Multi-Spawn Gold, the next two add Critical Damage and Critical Chance, and level 500 adds Specialty Gold.

From level 1000 the list turns general: four extra Mana Capacity, then All Gold, All Damage, All Hero Damage and finally a big Boss Gold bonus at 6000. He is a utility pick rather than a damage carry.
