Help Action in D&D 5e (Explained): How to Give Advantage the Right Way

1 April 2026

You’ve been there: the boss is one solid hit from tipping, but the dice are sulking. Your sneak-attack friend is one roll away from a story beat, and you’re holding a sword like you’re supposed to solo every problem. Help is the rules text that says you don’t have to. It’s an action that buys advantage for someone else’s next attempt, if you set it up lawfully.

Pair this with advantage & disadvantage for the dice procedure.

What Help does (two modes)

When you take the Help action, you choose one:

Help on an ability check

You assist one ability check another creature attempts before your next turn. The friend gains advantage on that check if your narrative setup makes sense (DM gatekeeps absurdity, not kindness).

Help on an attack

You feint, distract, or otherwise set up a foe within 5 feet of you so an ally lands a hit: the next attack roll that ally makes against that target before your next turn has advantage.

Range matters for attack-Help: you need to be close enough to meaningfully contribute, not sniping “Help” from a balcony without features that say otherwise.

When Help beats swinging your own weapon

• Burst rounds where one marked hit matters (sneak attack, smite, a big spell attack after setup).
• Your own to-hit is weak this tier, but your HP can eat being adjacent.
• You’re holding a defensive posture while enabling the party’s specialist.

Common mistakes (easy to fix)

• Helping the wrong target, focus fire first; advantage on a doomed side target is story, not math.
• Forgetting it’s only the first qualifying attack, not the whole Extra Attack sequence unless your table misremembers generously.
• Trying to Help everything every turn, sometimes damage or control is the correct action.

Related rules that love Help

• Prone setups (melee advantage combos).
• Grappled tiles where someone must stand near danger to matter.
