Serpentine Eidolon Question

I noticed that it's possible to increase the Base Speed of an Eidolon through the Limbs Evolution (thus growing extra pairs of legs). It's also possible to increase an Eidolon's Climb, Swim and Fly speeds through multiple Evolutions.

My question is this: How does one increase the Base Speed of an Eidolon with the Serpentine form? 20 feet is rather slow... and I don't want my nice, sleek serpent body to suddenly start sprouting legs just so I can move faster. Am I missing something somewhere?


I would pay for the Limb (Legs) and describe it as a longer, faster body. It would have the side effect of not making you more stable, as you do not have the actual limbs, just the movement increase that the evolution adds.
As for PFS I have no idea.

Those who have no legs are immune to tripping, so not having the legs be there at all would actually be an advantage.

If this were a bipedal or quadrupedal form of eidolon, I would completely allow the player to take the legs evolution for more speed, and even get the benefit of a bonus against trip, without needing the legs to actually be there.

But getting more move speed whilst maintaining the immunity to trip you would normally lose is too much. If you want you could try to flavor it that they are treated as their "virtual" leg count for all purposes, including removing immunity to trip, but it would be kinda weird. "Wait... I just tripped a snake?!"

RAW you have yo take limbs(legs) and that gives you actual legs (making you trippable).

If your GM is kind, he may let you take a 2-point evolution that does not give you legs and only increases base speed by 10ft. I would certainly allow my players to do this, since the serpentine form is the least min-maxed of the base forms and thus I don't think I'd be creating a balance issue by allowing this.

Hmm, that definitely sounds reasonable.

I just don't like the "having to take legs" thing. And while I know what I would personally allow as DM, I was mostly wondering if there was an Evolution or a RAW thing that I wasn't aware of... not having UM yet and not being a PFS participant.

Just seems strange to me that you can grant a Serpentine Eidolon extra Swim, Climb, etc., movement but not it's Base Speed. If I had to houserule it, I'd probably make it a 3 pt Evolution or something.

Just wondering if there was something "official" that addressed this.


I might turn it into a set of centipede legs, No claws and such, but no tripping either.

I'd at most make it a "3 point the first time, 2 thereafter". You're basically paying the 1pt for the trip immunity (which is circumstantial at best). The other eidolon types can take climb just as easily, after all.

Serpentine Celerity - 1 point: Allows the taking of the "Base Speed Increase" evolution. This evolution cannot be taken if the eidolon also has the Legs evolution.

Base Speed Increase - 2 points: Increase the eidolon's base speed by 10 ft. Cannot be taken by eidolons that lack legs.

I really don't think that's necessary.

1. Serpentine base form is not overpowered compared to quadrupeds or bipeds. There's nothing specific about moving fast and not being trippable that synergizes particularly well, so moving faster is equally valuable for all of the base forms.

2. When quadrupeds or bipeds pay 2 points for additional legs, they get the following: a] +10 movement speed and b] they become harder to trip.

3. Since "+10 movement and harder to trip" is a balanced ability for 2 evolution points, it is reasonable to make "+10 movement" cost the same amount for the already-untrippable serpentine. It's just not a RAW option and thus you'd need to convince your GM to allow it.

I really don't think that's necessary either. The serpentine already has trip immunity. Why is he paying another 1 evolution point for it?
