For any Creature/Dino you can use this to have the Dino's take more or less Damage
and you can make them do More or Less damage, just follow these simple steps down below.

Example: You will have to add the lines into your server's Game.ini file.
Add your lines below this section or create one:
[/script/shootergame.shootergamemode]
For example to half its resistance 0.50 means take twice more damage.
DinoClassResistanceMultipliers=(ClassName="Platinum_Character_BP_C",Multiplier=0.50)
TamedDinoClassResistanceMultipliers=(ClassName="Platinum_Character_BP_C",Multiplier=0.50)

First line above is for wild dinos and second line is for tamed. This will make it take twice the amount of all damage taken! Value of 1.0 is default normal.

To Nerf the damage certain Dino's do you can use the following lines:
DinoClassDamageMultipliers=(ClassName="Gemstone_Character_BP_C",Multiplier=0.50)
TamedDinoClassDamageMultipliers=(ClassName="Gemstone_Character_BP_C",Multiplier=0.50)

Follow this example for other creature spawn ID and if u want change damage it does, swap DinoClassResistanceMultipliers to DinoClassDamageMultipliers instead.

If you feel it's too powerful, nerf it's damage and resistance multipliers to 0.50 or lower.
If it's too weak for you, boost it up to 2.0 or higher.
