This is a horribly underused option, IME. When I've used it as a player, I get strange looks from the other players.By the way, you always have a viable action to take: dodge.
Ha, yes, that's another use case I forgot about: Since Delay has been abolished, the only way to switch your position in combat order (if going by the book) is to Ready. It doesn't affect my play group since we use a variant on side-based initiative, but normally this would be a fairly common scenario.Ready to cast fireball on the fighters turn so that I can clear a path to the big bad guys in the back for her.

Unfortunately, readying a spell is a terrible tactic, because of two reasons:
1) If the trigger doesn't occur before your next turn, or if you give up the readied action to do something else (i.e. use your reaction for OA or else) you lose the spell slot anyway. An intelligent enemy could very much decide to not attack you, if he sees you readying a spell (which is actually quite visible, since you cast the spell on your turn and only release it on your reaction), to make you waste your spell.
2) Between the casting and the releasing of the spell, you are concentrating, even if the spell itself doesn't require concentration, so you are even more vulnerable to losing the readied spell.
By the way, you always have a viable action to take: dodge.
Good call.I've DMed 5e so far for 3 different gaming groups (plus one PbP game, not considered here) and all those groups were mostly of beginners, so I never actually told them that this action exists in the game as a combat option. When I have beginners, I purposefully keep things simple
Sometimes, complexity is the price of simplicity. They clearly wanted to avoid your initiative order changing in combat, so no Delay, and Ready uses your Reaction. Simple, right?Back to my yesterday's musings, I was asking myself why not try to explicitly tell the player myself about the ready action, and see how they use it? So I went to take a second look at the PHB description of it, and then I searched the Sage Advice compendium and website to have a better picture. And my conclusion was: why bother?![]()
Heh. ;|It's more clunky and complicated that it really needed to be, otherwise there wouldn't be so many Sage Advice about it (and you pretty much need to read those to understand how Ready works with or against spellcasting).
And you give up any other use of your already precious Reaction.And it doesn't seem a generally useful tactic. The main dealbreaker is how your readied action takes effect after the trigger...Overall, except presumably in corner cases, it doesn't really sound to me like readying any action against any trigger is worth. You're better off just taking your action now than to wait until a trigger.
Seriously, though, yes, Ready has gotten used now and then. Like any other action declaration, I use judgement in resolving it rather than sticking to any real or imagined RAW. So if a player wanted to ready an attack or grapple or whatnot to 'interrupt' a spell being cast, or get in the way of an attack or whatever he feels it's important/useful to do with some timing rather than right now, he can make the attempt.But I suppose that other gaming groups are using it regularly, so I gotta ask: how often do you use the Ready action, and what is your typical use of it?
It's not worth telling them about, though, honestly. If a player declares an action that Readying would help resolve, use it - explain it in that context - and move on after, no different than any other ruling for being loosely based on an existing, complicated/problematic rule.Please don't just play devil's advocate or come up with fabricated scenarios where you think you would use it... I want to hear real stories of players/DM using the ready action satisfactorily, so that I can convince myself it's worth telling my own players about it![]()
That's actually something to keep in mind, is that it effectively lets you take two turns in a row (if you don't mind pre-committing to the first action). If you're fighting a group of ogres or something, and they're likely to break formation after the first fireball, you can use this to hit them twice before they know any better.Ready doesn't change your combat order RAW. However, you can use ready to go after another player such as "after the wizard clears a path I charge in" I don't really like this because it feels weird to get two turns so close together. I preferred 4e rules that permanently moved your turn order.
One common scenario is when a ranged attacker keeps retreating behind cover, making use of the overly-generous movement rules to become a non-target whenever they aren't attacking. You can ready an action to fire back when they come out, but you only get one attack and they get all of theirs.Overall, except presumably in corner cases, it doesn't really sound to me like readying any action against any trigger is worth. You're better off just taking your action now than to wait until a trigger.
