The Volunteer

The Volunteer is an augment. When obtained, it causes all future levels to contain a Very Safe Laboratory, which contains prototype augments.

It can be found as a drop from Gold Chests. It can also be found in Shops with a price of 15 Nuts.

Synergies

 * Fortune Stabilizer pairs well, as it removes the possibility for a shop to be replaced by a Lab, as you'll always be able to access them in the boss antechamber.

Trivia

 * As Very Safe Laboratories replace in-level shops, it may become harder to find items to purchase in a given run.
