A mod that adds the ability to gain Toxicity, a status effect, everytime you use a Max Doc or Bounce Back. You can gain Toxicity up to X times (adjustable, 4 by default). By default, the effect lasts for 30 seconds, but you have the option to make it more difficult to activate (configurable).

When you use a healing item, the amount of Toxicity increases, and the timer is reset to the full duration. You can set the maximum amount of Toxicity to a fixed number or percentage.

You can also set the visual effects to be more noticeable. There is an option to use a vignette and color change for the Toxicity effect.

This is a fairly simple mod that doesn't require much knowledge of the game engine.
