Prince of Darkness

Soulbind is the final upgrade of the Wizard Monkey in BTD6. It allows towers around its radius to sacrifice towers upon losing lives to gain extra lives. It costs $TBA on Easy, $TBA on Medium, $TBA on Hard, and $TBA on Impoppable.

Sacrifices
It will only sacrifice towers if lives are lost. The amount of lives gained depends on the monetary value of the towers. More monetary value of sacrificed towers will gain more lives. For every $100 sacrificed in financial value for the Medium Difficulty price (regardless of difficulty), one life is gained.
