Cunning Strike
Feature of the Rogue class, from level 5. 7 options.
Daze

The target must succeed on a Constitution saving throw, or on its next turn, it can do only one of the following: move or take an action or a Bonus Action.
Knock Out

The target must succeed on a Constitution saving throw, or it has the Unconscious condition for 1 minute or until it takes any damage. The Unconscious target repeats the save at the end of each of its turns, ending the effect on itself on a success.
Obscure

The target must succeed on a Dexterity saving throw, or it has the Blinded condition until the end of its next turn.
Poison

You add a toxin to your strike, forcing the target to make a Constitution saving throw. On a failed save, the target has the Poisoned condition for 1 minute. At the end of each of its turns, the Poisoned target repeats the save, ending the effect on itself on a success.
To use this effect, you must have a Poisoner's Kit on your person.
Stealth Attack

If you have the Hide action's Invisible condition, this attack doesn't end that condition on you if you end the turn behind Three-Quarters Cover or Total Cover.
Trip

If the target is Large or smaller, it must succeed on a Dexterity saving throw or have the Prone condition.
Withdraw

Immediately after the attack, you move up to half your Speed without provoking Opportunity Attacks.
