Ending Concentration spells

[DeathKorpsman]

OK, regular old run-of-the-mill concentration spells are easy to end, just stop concentrating. My question rises from spells which have a duration such as: Concentration +1 round/level...etc.

The Core Rulebook states that Concentration spells are, by their very nature, dismissable because you can just stop concentrating on them and they end. However, some concentration spells DON'T just end when you stop concentrating and the book makes no special exception for these.

It seems that, unless there is something I've missed, this can be interpreted one of two ways:

A) These types of spells, once you stop concentrating, continue for whatever duration they have listed after concentration ends and there is nothing you can do about it short of Dispel Magic or similar.

B) These types of spells are instantly dismissable, with no action required, if you end your concentration and you as the caster wish the spell to end as the spell is inherently dismissable.

Which of these interpretations (or any mystery interpretations there may be out there) is correct and what rules reference is there which covers it?

Thanks in advance for any useful input/research on this topic.

Option 'A' is correct, with the added caveat that the spell may be dismissable anyway, if you're willing to spend a standard action to do so (and the spell allows it).

Each spell can be a little different. Note how Mislead allows you to dismiss the invisibility, but not the image.

Spoiler:

School illusion (figment, glamer); Level bard 5, sorcerer/wizard 6

Casting Time 1 standard action

Components S

Range close (25 ft. + 5 ft./2 levels)

Target/Effect you/one illusory double

Duration 1 round/level (D) and concentration + 3 rounds; see text

Saving Throw none or Will disbelief (if interacted with); see text; Spell Resistance no

If it's a significant problem that the spell not go away, you could always ask your DM if you're allowed to dismiss it. It wouldn't be an unreasonable houserule at all.

Having that spell as a reference makes it very clear. Thanks a bunch for that. Wasn't familiar enough with all the different spells to be able to think of/find one easily which bridged the rule gap. I'm not worried about a houserule per se, just knowing that a certain spell is intentionally a certain way helps a ton.

You're welcome. :)

Loathsome Veil is a concentration spell that also clearly notes itself as dismissable:
