How would I create a double damage effect

[W00lyP4rr0t2]

Working on a custom plugin for my server currently and realised that the damage taken would be different depending of the victims armor so I can't just use damage.
Here is the script i have so far:
on damage:
if attacker's tool is named "Warden Sword":
chance of 2.5%:

How would I make the damage the victim takes double?

Well first of all, if this is what you mean, you could use Minecraft's /damage command to your advantage to set the damage of the Warden Sword.
Example:

on damage:
    if attacker's tool is named "Warden Sword":
        execute console command "damage %victim% 5 minecraft:generic_kill by %attacker%"

You could find the amount of damage the Warden Sword does, (should be in the attack damage area when you hover over the item) and replace the 5 in the example with it. This will also keep a death message when you kill someone. Should say "victim was slain by attacker" if they die by the sword.

Yes but the damage command pierces through armour which I dont want, is that possible?

no the code he provided is correct, he's not damaging the victim but changing the damage of the sword. I don't know if the command will be executed before the event triggers though.
