In combat, one team mate may 'Help' another willing ally:


You can lend your aid to another creature in the completion of a task. When you take the Help action, the creature you aid gains advantage on the next ability check it makes to perform the task you are helping with, provided that it makes the check before the start of your next turn.

Alternatively, you can aid a friendly creature in attacking a creature within 5 feet of you. You feint, distract the target, or in some other way team up to make your ally’s attack more effective. If your ally attacks the target before your next turn, the first attack roll is made with advantage.

The Question I have is: Can this be used as a bonus action, or used whilst concentrating on a spell?


If something can be performed using a bonus action, it is always explicitly stated in the description. The lack of such a statement indicates that it can only be used as an action.

Concentration is only broken by specific things, which are listed on page 203 of the PHB and are:

  • Casting another spell that requires concentration (*)
  • Taking damage
  • Being incapacilated or killed

(*) Readying a spell or casting a spell with a casting time over 1 action also requires concentration (PHB 193 and 202, respectively).

Taking the Help action is none of these and thus will not interfere with concentration.

    \$\begingroup\$ Page 202 of the PHB adds an additional condition that is easily overlooked: When you cast a spell with a casting time longer than a single action or reaction, [...] you must maintain your concentration while you do so. \$\endgroup\$ – nwp Jul 19 '17 at 14:18
  • \$\begingroup\$ And that includes reading a spell action. While you are holding that spell, you are concentrating on it ... Even if the spell doesn't require concentration. "and holding onto the spell's magic requires concentration" PHB 193 \$\endgroup\$ – J. A. Streich Jul 19 '17 at 15:05

Help is an Action, it does not break concentration

In the PHB, 192 under Actions in Combat, Help is listed as option.

When you take your action on your turn, you can take one of the actions presented here...

This is not a Bonus Action, but purely your Action.

For Concentration, the only things that can break that are from PHB, 202-3:

When you cast a spell with a casting time longer than a single action or reaction, you must spend your action each turn casting the spell, and you must maintain your concentration while doing so...

Casting another spell that requires concentration...

Taking Damage...

Being incapacitated or killed.

In addition, Readying a spell would also end concentration (as you are concentrating on a new spell) from PHB 193.

Using your action does NOT break concentration unless the above occur.

  • \$\begingroup\$ And holding a readied spell also uses concentration, and there are a handful of abilities that require you to concentrate as if on a spell... \$\endgroup\$ – J. A. Streich Jul 19 '17 at 15:07
  • \$\begingroup\$ @J.A.Streich Can't ready a spell and take the Help action at the same time, though. \$\endgroup\$ – NautArch Jul 19 '17 at 15:36

    \$\begingroup\$ I wasn't suggesting that you could. I was suggesting your list of what breaks concentration is incomplete. \$\endgroup\$ – J. A. Streich Jul 19 '17 at 15:44
  • \$\begingroup\$ @J.A.Streich Not really... A readied spell is a cast spell, so "casting another spell that requires concentration" covers it. \$\endgroup\$ – T.J.L. Jul 19 '17 at 16:00
  • \$\begingroup\$ @T.J.L. Very true, but having the extra line in doesn't hurt and helps clarify something that may not be known. \$\endgroup\$ – NautArch Jul 19 '17 at 16:02
