Question about full round casting times and readied actions

Caster A is casting a spell with 1 full round casting time. Can you ready an action to do some right before the spell is finished casting?

So long as you are not Caster A, and your character knows enough about spellcasting to know when a spell is almost-but-not-quite complete, sure thing.

Not IMO, no. You can ready on a trigger condition, you cannot ready on a trigger future condition. Your action occurs "in response to that condition."

As another invalid example, you cannot ready to cast dimension door defensively if you are about to be successful hit with an attack.
 

Agreed with I2k for a part. You cannot ready for something like "an attack that is going to hit". Since you have no idea till it actually hits unless you have some kind of prescience. You can ready on "an attack that hits" aka after it hits and on "an attack" when it takes place.

But I *would* allow people to ready on completion of a spells casting. But the spell has to lend itself for it. For example if someone wants to ready a "wall of ice" when someone completes a fireball spell for example to have it blow up in his face I have no problem to allow it. You just ready on the moment the bead of fire streaks from his outstretched hand.

Doing it when someone starts casting to interrupt someones line of sight is cool with me to, but the person in question doesn't finish his casting and doesn't lose the spell. He can just choose to forgo the completion of the magical force.

In other words, I'd allow readying on specific actions as stated above about the fireball spell. But not other kind of spells that just have some kind of effect as dispel magic or hold person or whatever. Since the readying in case of fireball and other kind of spells like that is not tied to the spells completion or casttime as much as an effect that takes place between completion of casting and the spell taking its direct and final effect.

Back to the main point, I would not allow a ready in the case of a fullround action. But a normal ready or interruption without even readying since you get another turn before he completes his action is perfectly fine. But again, if he chooses to forgo I would not let him loose the spell slot. Allthough anything that forces a concentration check which is botched or a spellcraft check offcourse would make him loose the spell since it isn't voluntairy.

Guess im rambling a bit but hope Im making at least SOME sense haha.
 

I'm a bit confused as to why the OPs intent is a problem. He want a readied action to go off right before a spell is finished casting. So AFAIK readied actions go off before the trigger right? So he readies X standard action with his trigger being Caster A finishes casting his spell. Caster A finishes his spell, the readied action goes off, before the trigger, and so it happens right before Caster A finishes casting his spell. The Readier would have to have some spellcraft, IMO to be able to know when a spell is compeleted but I don't see the problem outside that.

Again what infiniti said coverd it pretty much.
 

I agree with I2K. Further support for this is that you can ready a standard, move, or free action. Each of these actions must be taken on your turn, only immediate actions can be taken during another creature's turn. Taking a readied action changes your place in initiative but does not allow you to take actions during another creature's turn (after A has begun casting but before A has finished casting). If A is casting a full round spell and you want to take said readied action you must take it before or after Caster A's action, not during.

No, that's wrong. You can indeed Ready an Action to take place during someone's action. Readying to interrupt spellcasting is one of the main benefits of the Ready Action.

Definitely not the case. Interrupting other creatures' actions is one of the primary uses of the Ready action.

You can Ready an action to occur "just before <character> completes <action>" providing you have some means of identifying exactly when that action is almost complete. In the case of spellcasting, that's a Spellcraft check, and I'd use the standard DC for identifying a spell being cast.
