Может:

+25% bullets per shot
+10% attack speed
-25% ammo
-25% damage
-25% accuracy

+On hit: one target at a time is marked for death
-40% Health From Healers on Wearer (this could be counter acted by the Quick-Fix that heals 40% faster but you would also be dealing with the downsides of the Quick-Fix)
-25% Slower Firing Speed
No Random Crits
Basically you would be doing 10% more damage on a single target in exchange you heal slower from medi-guns, dispensers, and the cart.. Its a straight up upgrade in damage while being a straight up downgrade in being a meat shield for damage. Unique enough to change your play style as a Heavy but not powerful enough to stay alive for long periods of time

that sounds awesome.

[+] On kill or assist, the victim leaves behind a peanut basket that acts as a Small Health Pack which can provide up-to 25 points of Overheal.

[+] Confectioner's Delight: Dealing damage provides peanuts to Medics healing you, healing 1-4 health, based on fall-off/ramp-up.

[+] +20% accuracy bonus

[-] -35% damage penalty

I think this should be a brass beast reskin to be honest this looks really nice
