Can serpent eidolons be tripped?

[Ravingdork]

I doubt many would argue that a serpent eidolon isn't immune to tripping.

But what if I have a serpent eidolon that has limbs (legs) twice, is it still immune to trip like all serpentine monsters in the Betsiary? Or does it just get a +4 CMD bonus to avoid getting tripped?

[Mikaze]

Damn. I can visualize this both ways. If ever it had a leg knocked out from under it, it would still have its serpentine build to fall back on. I'd probably have it lose whatever benefit it gets from legs for the duration of the trip, but no more than that.

It just the get the +4 CMD bouns to avoid getting triped. Immunity to tripping is greated to serpents because they have no legs, rather than because they are serpentine.

Yeah the minute you give it the Limbs (legs) evolution they'd be vulnerable to Trips!

But once you tripped them, they would still be able to move and fight as serpents would (and thus be effectively immune to the prone condition), wouldn't they?

[Karui Kage]

Not really. Think of lizards or salamanders, which have rather serpentine bodies with legs. Remove their limbs and they can't do squat. A snake specifically evolved so it could move around without its limbs.

In any case, I would say that as soon as you give a 'serpentine' eidolen limbs, it's no longer immune to trips.

I disagree... I think it would be still relying on it's torso for movement and since the legs are an add-on they would work more like oars on a boat to increase speed. If I was a large snake like creature with two legs I walked around with, I would become a biped with a snakelike body by that logic. Plus, two legs holding up all that weight and a plus +10 to speed, I'd think they were helping to propel it forward, not for running about on. Lastly, if I did have them on two legs, I'd treat them as a biped and not give them a bonus for standing on two legs and getting tripped.

Penalizing a player for upgradig by spending points and in exchange losing an immunity? Sorry, I disagree, but it's you're game... GM it accordingly... :D

EDIT: Would anyone take only one set of legs if they got this penalty? With multiple legs (at least 3 sets) I could see it, but not with up to two (otherwise you're a biped or quad).

[King of Vrock]

Actually the best example of this would probably be the Behir. It's a serpentine creature with Legs that cannot be tripped.

So I guess I'll change my answer to No and say it probably shouldn't lose that advantage.
