Weapon Actions:

While wielding a weapon you are proficient with, you may perform up to three unique Weapon Actions. You can only use one Weapon Action per turn. When you hit a creature with a weapon attack, you can expend one Weapon Action. Once expended, each weapon action recharges on a short or Long rest.

Saving Throws. Some of your weapon actions require your target to make a saving throw to resist the weapons effects. The saving throw DC is calculated as follows:

Weapon Action DC = 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice)
