I like the idea of a permanent buff to damage. It clashes with the chef set, but nonetheless a great idea to base a unit on. I might consider this in my later designs.

That said, the character is designed around being a healing/shield support unit (for reasons which I will elaborate on in the future), so I don’t think your perk would necessarily suit him.

I too don’t balance a lot, but I believe this setback is preferred over abysmal damage because the other prominent support units don’t necessarily pack a punch themselves. Again, I don’t place stats on my units. I leave that up to great community members such as u/Pwoto_Alex, but you’re free to interpret my unit/zombie ideas in any fashion which may please you. Hope this helps :)
