Fireteam can choose between Knife and Machete.
Knifes have faster attack speed but deal small damage and can be used to deal back stabs ignoring the perks of armor.
Machetes have slower attack speed and deal moderate damage also longer reach but cannot deal back stabs.
Every use of Knife or Machete uses stamina: Knife uses 20% stamina and Machete uses 25% per attack.
Keep the Parry ability but depending on Predator’s melee Weapon the knife or machete will take some damage as an object and the human loses some of it’s stamina and it will:
Knife or Machete vs Claws = able to parry, loses 25% stamina per parry, can be used 3 times before destroyed.
Knife or Machete vs Elder Sword = able to parry, takes 50% stamina per parry can be used 2 times before destroyed.
Knife or Machete vs WarClub = one time parry, takes 75% stamina and human takes only 25% of the damage BUT after the parry the knife cannot be used again only for cutting the net.
Knife or Machete vs Combistick = Unable to parry
And loosing the knife or machete means that later in the game if the Predator nets you down, you can’t escape by yourself, the other teammates need to cut the net for you.
Knife damage should be reduced but it should deal a little bit more damage as a bonus in case it is used from the back. If used from the front the Predator should be also able to parry the attack.
