That pesky concentration check...


Rules Questions

Sovereign Court RPG Superstar 2009 Top 32, 2010 Top 8

Ok, here's the scenario. I'm checking for the next time I have him at the table.

Druid on a lion (Not an animal companion). Order of events is as follows.

1) Druid orders kitty to move/charge/pounce. This takes up his move action. On his standard he starts a ful round action (legal per PRD*).
2) Lion moves normally pounces.
3) Next round he completes the full round action (normally Call Lightning, or summon nature's ally.)

Now, I am reading this as requiring a concentration check.

Two questions.
a) Am I right?
b) How difficult should it be? Specifically which of these apply?
Vigorous motion while casting 10 + spell level
Violent motion while casting 15 + spell level
Thanks.

Spoiler:
I missed in the PRD that completing a Full Round Action on the next turn burns your standard. That helps.

Just below the table, the Magic section calls out a "moving mount" as vigorous motion, and a "galloping mount" as violent motion. I think I'd include a charging pounce as at least violent, and perhaps extremely violent, for a DC of 20 + spell level.

Hmm, so I think I'll use this as a guideline.

Vigorous: standard move.

Violent: Double Move/charge of standard move or less.

Extremely Violent: Charging more than standard move.

Thanks RainyDayNinja!

You are correct that casting a spell while mounted, especially if the mount is moving,requires a Concentration Check.

"Casting Spells While Mounted: You can cast a spell normally if your mount moves up to a normal move (its speed) either before or after you cast. If you have your mount move both before and after you cast a spell, then you're casting the spell while the mount is moving, and you have to make a concentration check due to the vigorous motion (DC 10 + spell level) or lose the spell. If the mount is running (quadruple speed), you can cast a spell when your mount has moved up to twice its speed, but your concentration check is more difficult due to the violent motion (DC 15 + spell level)."

Also, any damage taken from his first turn when he begins to cast until his second turn when he completes the spell would cause another Concentration Check for Injured While Casting, DC 10 + Damage + Spell Level.

I am impressed that he has a non-animal companion lion mount. I think in this case there are a lot more checks needed to make sure the lion knows what to do in combat. I am assuming that the lion has been combat trained in the sense that it learned how to fight with a druid on its back, etc.


I think your confusing something, a full round spell and a full round action are two different things. I do not think it allows anywhere to start a full round spell as a standard action. I may be wrong however.

I am pretty sure this can be used on spells with a casting time of 1 round.

"Start/Complete Full-Round Action
The “start full-round action” standard action lets you start undertaking a full-round action, which you can complete in the following round by using another standard action. You can't use this action to start or complete a full attack, charge, run, or withdraw."


No where in that line does it suggest spells with "Casting Time 1 round" are full round actions, they are not. They use different mechanics.

When i charge or spring attack, I do not finish at the start of my next turn. You cannot break a 1 round spell up into two standard actions because no where in the rules does it explicitly say you can do so.

Edit: I think there is a thread around right now talking about confusion about what a full round action is and how much time it takes up but i do not have a link.

It says here that they are full round actions:

"A spell that takes 1 round to cast is a full-round action. It comes into effect just before the beginning of your turn in the round after you began casting the spell. You then act normally after the spell is completed."

Why would it not be allowed to follow the same rules when it does not say anywhere else that it is treated differently.

Besides, it makes the caster use 2 Standard actions in two different rounds to cast it. It was allowed back in 3rd and 3.5 and it does not appear that Paizo has switched anything out so unless there is a ruling against it, it is perfectly legal per the rules.

Again, it still leaves you open to several Concentration Checks from one round to the next.

Can you cite/link that in the PRD?

I am not that good at links but here goes.

Magic It is under Casting Time after all of the schools in the Spell Description section.

Edit: Here is a direct link on the d20pfsrd.


Oh then it works, my appologies i was going by memory. I did not realize they were labeled as full round actions. (the 1 round spells i mean) I had assumed they were a separate thing.
