Prince of Darkness

"Bind as many souls to the Wizard as you dare and it just might save your life..."

- BTD6 description Soulbind is the final upgrade in Path 3 of the Wizard Monkey in BTD6. It allows the player to bind as many towers as they wish to the Wizard so it can sacrifice the towers to gain extra lives when Bloons escape. It costs $TBA on Easy, $TBA on Medium, $TBA on Hard, and $TBA on Impoppable.

Sacrifices
The Wizard will only sacrifice towers if lives are lost. The amount of lives gained depends on the monetary value of the towers; a higher value will result in more lives gained from a sacrifice. When a tower is sacrificed, you get one life for every $100 sacrificed in financial value for the Medium Difficulty price (regardless of difficulty).
