Does the Fey Bloodline, "Laughing Touch" ability work on constructs or undead?

I assumed that this is an enchantment/compulsion spell-like ability like hideous laughter, however the player (you know who you are!) is adamant that Laughing Touch works completely differently. He suggests that it is not an enchantment/compulsion effect at all but rather is a burst of unadulterated feyness which stimulates a response somehow to laugh...Not sure how or why my animated object with no physiology, immunity to mind affecting and no int should be subject to this...

Any thoughts?

My thoughts are, no. They're both immune.

As written, yes, this effect can affect undead and constructs because we forgot to say "This is a mind-affecting effect." Which it should be, in my opinion.

I can't imagine this is anything other than an error of omission. I'll flag it for future errata.

It works, because there's no limitation written into the ability.

Trying to apply logic to the fluff of game rules is the first step down a slippery slope into madness.

Rules-wise? They are affected. Nothing in the rules mentions any limitation of that kind. Since this is the rules forum, that would be the correct answer.

I wouldn't mind a DM who house-ruled it though. It makes sense and Fey is a decent bloodline anyway. However, it isn't a very powerful ability (kind of useful for gish-types, but nothing more than a last resort for any serious sorcerer - melee touch? UGH!).

On the other hand, I like magical abilities that "break the rules" (or norms, rather). I like Witch's cackle working in an area of silence and I somehow like the feyblooded sorcerer being so "weird" that it can force even a table to laugh.

On the other hand, I prefer fey as strange, somehow very unnatural and alien beings even though they live in forests.

I appreciate that "as written" the power affects constructs, undead, or presumably, plants...as long as they are determined to be a "creature." I also appreciate the cautionary statement of how applying logic to fluff game rules can cause or exacerbate mental instability. I do have a problem with that....the logic-to-fluff thing, not the mental instability.

I think, perhaps, what I appreciate most of all is someone weighing in with an "official" position and flagging this for future errata!

Thank you all for weighing in!

Sorry to res a dead thread, but is this ability considered a compulsion spell, thereby granting the Fey sorcerer a +2 to the DC? Does being a spell-like ability exclude it from benefits under "whenever you cast a SPELL of the compulsion subschool?"

Never mind. I answered my own question. Apparently, Laughing Touch doesn't have a save associated with it.

It isn't considered a spell at all. PF defines spells and spell-like abilities as two very different types of action. Any modifiers that affect spells, such as Spell Focus or the sorceror bloodline bonuses do NOT affect spell-like abilities, including the bloodline powers. In order to increase the DC on the bloodline powers, you would need to take a monster feat like Ability Focus, which gives a +1 to the DC of a natural or spell-like ability.
