What is the Concentration DC for casting spells while tied up?


Rules Questions

Tying someone up is now a function of the grapple rules. Normally, when grappled or pinned, you must make a concentration check in order to cast a spell. When you are tied up, you are considered pinned.

However, no one is holding you, so it doesn't make any sense to use the DC for being pinned (which assumes someone is holding you and therefore includes your pinner's CMB).

I ask because I took Silent Spell and Still Spell for my a sorcerer specifically to get out of situations like being bound, gagged, and stripped naked.

You can't perform somatic components or get to material components that you didn't previously have in hand, but that seems to be understood.

For Verbal-only or no-component spells and spell-like abilities, the concentration DCs for being grappled and being pinned are the same (at least, as at my 4th printing). You should apply the binder's CMB because his ability to immobilise you effectively is in question even though he's not personally present, just as it would be for trying to get out of your bonds.

And if nobody has the binder's stats? What do you do then? I've had more than one character drugged by the GM, only to wake up tied up--tied by a background character he never had any info on.

I feel like it should be a static DC, like the entangle DC, for example.

The GM should have the stats, or set a default CMD based on the typical NPC who would be performing such an action.

Arg. My GM has to ask me how to calculate CMD more often than not.

I really don't see why a dragon or balor would be better at tying ropes than a master thief. I mean COME ON! THEIR HANDS ARE TOO BIG! Strength and size should have nothing to do with tying knots, much less determining my concentration DCs for being tied up.


The DC should be determined by randomly opening up any three Pathfinder rulebooks and picking the higher value of the page number or the highest printed number on that page. Average the three results.

If you have Still Spell, no Concentration check is required.

Still Intensified Maximized Empowered Shocking Grasp merely a 7th level spell slot. It's also gonna be a real surprise when someone's grappling your sorcerer. :)

I believe the strength aspect is strictly dealing with how tight the knot is. Think about machine tied knots. Those are virtually impossible to pry apart easily because the machine can apply much more force when tightening the knot.

So what does your GM do when the barbarian and the rogue try to struggle out of the ropes? This sounds like a wider problem than just concentration checks.

Balors use whips pretty well, so I think they can tie ropes just fine. I agree, though, that basing it on STR doesn't make much sense here. Bring back Use Rope Agile Maneuvers would help the master thief here.

This is not a listed effect of Still Spell. You must make concentration checks for any casting when grappled and you can't use spells with somatic components at all - so Still Spell allows you to try a spell that normally would have a somatic component.

It's likely to be a stressful situation, and it's a condition in which one is not accustomed to casting.

Like casting in wind and rain, a Concentration check is appropriate for casting while bound.


I generally hold that Still Spell allows you to cast spells while bound with no Concentration check. It's very different from being jostled, shaken, whipped or pureed while casting a spell.

I generally hold that Silent Spell allows you to cast spells while gagged.

Makes both of those feats more valuable, but, aside from Eldritch Knights, who takes Still Spell routinely? They're feats you take (and spells you prepare...) for days when you expect to be tied up and held at the mercy of your enemies...which comes up so often that of course you'll take this feat rather than, say, Reach Spell or Intensify Spell.

Clearly it's so much better than Quicken Spell. :)

Just use your level as the enemies CMB? - then it makes the challenge level appropriate and is approximately correct.


Anything with somatic components is impossible, anything without doesn't require a dc, you can do it with no arms, so having your hands and arms bound means nothing. If however you are on a rack, or being drawn and quartered, it is a different story... the damage/pain makes it a hefty dc.

That imo is the cleanest way to resolve the situation. If you are being actually grappled, it should be seen as something slightly different than being bound... as in, a DC to cast makes sense, you are effectively in combat, and being jostled around whereas bound =/= combat.

I agree with this interpretation and will likely present it to my GM.
