I looked at the zombie_bowie_flourish file but found damage was blank, and went into _zombiemode_bowie.gsc but couldn't find the script for how much damage it does.
How do you change the damage the bowie deals?

Damage is set in mapname.gsc:

	// Adjusts how much melee damage a player with the perk will do, needs only be set once. Stock is 1000.
	level.DLC3.perk_altMeleeDamage = 1000;
