Normally, haste grants the following benefit:

[The target] gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.

"Ready" is not one of those options.

Would it be very overpowered to allow readying one of those actions instead, using the extra action from haste?

"Just ready your regular action and use the extra Attack action during your turn" will not be accepted as an answer.

Example use case: Fighter McFighterson uses his attack (extra attack) to kill orc3; orc2 is out of range. So, he would want to ready an attack, rather than throwing another weapon or something.

    \$\begingroup\$ @NautArch the question seems to ask not if you can ready with the additional action, but whether allowing readying an approved haste action using the haste action would be imbalanced. \$\endgroup\$ Feb 15, 2019 at 21:16

    \$\begingroup\$ Can you define "harm" for the purpose of this question? And can you explain why the ability to ready with the regular action is not sufficient? \$\endgroup\$

Readying hasted Actions does not make haste overpowered

From your clarification in the comments, I will look at if doing so would make haste "very imbalanced and over powered".

In general

Rules-as-written, you can use your normal Action to Ready any available Action, while using one of the limited hasted Actions on your turn. With the proposed change, you could Dodge, Cast a Spell, or make a full set of Extra Attacks and still Ready a single attack.

Additionally, you could Ready two different Actions with two different triggers - one with your hasted Action and the other with your normal Action. When a trigger happens, you are explicitly allowed to ignore the trigger. "I Ready cure wounds to cast on the guy at my feet if he surrenders. I then use my hasted Action to Ready to attack the same guy if he instead fights back." You could only use your Reaction to respond to one of the triggers, but you could choose which one.

Dash and Disengage

Dash is useless to Ready. With your normal Action, you can Ready to move up to your speed, which is not the same as taking the Dash action. To make use of this, you would need some beneficial way to move outside of your turn without using your Reaction. Such an ability does not currently exist.

Similarly, Disengage is useless to Ready. It doesn't let you actually move; rather, it prevents opportunity attacks for the current turn.


If you find yourself in a bright room with a friendly Warlock, you could Ready a Hide action for when they cast darkness. Caveat: you can't move after this, so enemies will know exactly where you are, negating the benefits of Hide.

A Wood Elf could use Mask of the Wild to hide behind certain light obscurement that will appear later in the round (the web spell would probably apply). They would then gain the benefit from being unseen. Otherwise, just Hide on your normal turn.

Use an Object

The general statement applies here; you could now pair a readied Use an Object with any other normal Action (like a full set of Extra Attacks). You could Ready to use a Healer's Kit with the Healer feat to heal yourself or an ally. Note that magic items would not apply here, as they are not activated with Use an Object.


A Rogue can already use Sneak Attack twice per round by using their hasted Action to attack normally and readying their normal Action for outside of their turn. A hasted Rogue / Ranger with Extra Attack would gain one non-sneak attack with the proposed changes.


If, when presented with several options, one is (almost) always selected, then that option is probably overpowered. Would the proposed changes make haste a must-pick? Sorcerers with Twinned Spell will take it, but they do that anyway. Control-focused casters may choose it slightly more often, but fear and hypnotic pattern are encounter-ending spells that still surpass haste in most situations. Paladins and Rangers who receive haste as an extra spell will continue using it in the same situations.

A Rogue X / Horizon Walker Ranger 9 with haste would receive one additional non-sneak attack after the first round of combat. This is a significant power boost, but it shouldn't break the game. After all, a Gloomstalker Ranger 5 could be making 3 attacks in the first round of combat without spells, multiclassing, or feats! The rest of the Ready use cases are more about flexibility or niche situations than raw power.

Allowing a character to Ready a hasted Action will make the spell more powerful, as will any increase in flexibility. When presented with a modified haste as an option, it still will not be chosen every time; therefore, the changes presented will not make haste overpowered.

    \$\begingroup\$ I am curious of the (so far single) down vote. Because the base assumption that the user can ready its main action and still attack. So that, while unflavourful, having two readied action doesn't look overpowered to me.. \$\endgroup\$

  • \$\begingroup\$ @3C273 I just did an edit to clarify and compact things, so maybe that'll help? The difference between more powerful and overpowered may be an issue, as well. For example, the spell witch bolt is generally considered to be terrible. Raising its damage to 1d12+1 would make it more powerful. Would that make it overpowered? I think not. \$\endgroup\$

  • \$\begingroup\$ Good point, I reread it and noticed the rogue trick. also noticed that the question as a whole is less about OP and more about general game impact. My bad. The rogue trick alone is actually non-negligible if the GM doesn't make the player work for his reaction. \$\endgroup\$

Haste is limited because the designers thought it should be limited. It was open to them to choose Ready as an option and they didn’t.

Your example actually illustrates why. A Ready action always replaces an entire action which could be used on a multitude of actions and, as such, it has a considerable opportunity cost. Allowing it to replace the much more limited action choice that Haste gives massively reduces the cost, even if it is limited to the action types Haste allows.

    \$\begingroup\$ The answer would be easier to concur with if you replaced the word "massively" with something like "materially" or "substantively". \$\endgroup\$
