View Full Version : Pathfinder Fortuitous Weapons and Injured While Casting concentration checks: How do they mix?

Okay, let's say we've got a magus (we'll call her Maggy) who's monstrous form iii'd into a Thriae Queen—a huge monstrous humanoid with 15' natural reach. She's wielding her +1 keen fortuitous scimitar, so she threatens the whole area, and she's taken the Disruptive arcana, so casting defensively in that area is more obnoxious than usual. She's also got Combat Reflexes so she can take advantage of those extra AoOs with her fortuitous weapon.

Now let's say we've also got an enemy sorcerer (we'll call him Crosby) 10' away from Maggy at the start of his turn. He can't easily 5' step out of her reach, and while he might have Combat Casting, he's trying to get off one of his highest level spells, and he's worried he'll lose the spell if he casts defensively having seen Maggy's Disruptive feat at work. So he decides he'll risk taking the injury (this is why you don't dump Int, Crosby).

He casts normally, and provokes an AoO from Maggy. Maggy takes advantage of this, and strikes with everything she's got—let's say she hits, and since she hits, her fortuitous scimitar lets her make a second AoO at a -5. For the sake of the experiment, let's say that hits, too.

What happens to Crosby's injured while casting concentration DC? Does he have to add both instances of damage together and then add that to 10 + spell level? Does he only do the latest attack damage? Only the attack damage that was initially provoked? Or does he make two concentration checks, one for each attack?

He was damaged twice while casting and thus would need to make two checks (one for each hit.)


Injury

If you take damage while trying to cast a spell, you must make a concentration check with a DC equal to 10 + the damage taken + the level of the spell you're casting.

Each separate instance of damage therefore causes a separate check.

What Psyren said. It's no different from if two different people hitting you with an AoO while casting.

Generally speaking, though, even one instance of such damage is going to be worrisome, given the buffs flying around....
