Eidolon as a mount?


Advice

The Exchange

First let me say I have never run a Summoner character before, and haven't studied the class in detail. With that in mind my question becomes...
Can a Summoner create/have/use an Eidolon as a mount? is this build possible? I'm picturing a Halfling (or gnome or goblin) summoner with an Eidolon that looks like a wolf/dog. Is this possible, and what would the build look like?


The Mount evolution costs one point from your eidolon's evo. pool and is restricted to quadruped and serpentine type eidolons. It's about a quarter of the page down on the SRD Eidolon page. Though really all it does is make the eidolon suitable for use as a mount- as per The Ride Skill, you can still ride a creature which is unsuitable if you are okay a -5 on the check. So if you only need to guide it with your knees (so you can fight), that's a DC of 5, which you should be able to automatically make with skill points and feats/ traits.

As to the build, mounted archery feels like a good way to go- casting in combat is a bear, and casters themselves are squishy. So instead, use your mount's move to get away while you shoot arrows and spells.

That's something like what I was thinking. I ran a Druid multi-class in LG for years with the same Dog Companion - an animal companion which didn't know the Attack trick (NEVER went into combat). I was wondering about making the Eidolon a better mount - do/can I upgrade it's movement, strength, dex etc. making it a better mount but not a combat machine. I have NO intention of getting this guy next to the bad guys.

Nothing special to the build, just remember to start with the quadraped base, include the mount evolution, and customise as you like from there. Just remember that trying to ride up and down stairs is not going to be an easy Ride check, so remember to put points in that skill.

Yeah, I figured to max my Ride and prob. take the feat Mounted Combat.


Or even better mount your eidolon, get a lance, steal from the eidolon pounce, and make your GM cry.

lol - no, I fear that is not me. I'll leave combat to those persons that get their fun there.


You got it for the most part.

I'm going to point out that Quadruped isn't always better than Serpentine for a mounted build (or indeed in general). Yes, slower speed is a disadvantage for Serpentine, but that can be compensated for with Expeditious Retreat during combat (and out of combat it's probably irrelevant). Even a wand of it would go a long way.

Serpents also get the Climb evolution for free which helps a lot with mobility for mounts. He's unlikely to need Pounce because he's not building his character for combat. Serpents also have Reach for free, which can be nice for a character that likes to keep his distance.

Serpents also have the highest Reflex saving throws of all Eidolons, which helps with Evasion. It'll have more balanced saving throws in general because its weak save is Fort and he'll have slightly higher Con than Wis (especially if he puts an ability score increase in it and/or makes it Large/Huge), which contributes to Will, the weak save of Quadrupeds. Granted, Devotion helps with Will saves.

Serpentine is a viable option. It's usually weaker than the other two forms, but not always.


Another reason to choose Serpentine Eidolon is that they are immune to trip! Having a trip immune mount seems like a smart choice to me!

If you go serpentine and want speed, take fly at 5th level and sink a few points into it.

My idea of a mount is something that moves faster than I do, not slower.

That's fair. Though if you're a halfling, the Serpentine Eidolon is tied for speed. : P

Could also add a pair of feet for 2 evolution points to give it a faster base land speed, though that would remove the trip immunity. I stand by Expeditious Retreat as a suitable replacement, depending on the rest of your build and concept.

I'll likely go with a Quad - if for no other reason than I can go into town without the commoners running screaming from the giant snake.

Y'know, I need to take this whole "what would the peasants think" Idea more into account. Just because I can make a werewolf/hulk that can carry wagons, doesn't mean I should use him to toss orphans across buildings.

Ok... I just had a very silly idea. If I go with a Bipod build, and use the Eidolon as a mount, would it look like a kangaroo? I could then name my character something like Roo, and the Eidolon would be Kanga. This is just silly enough that I might just go with it. The Saddle would have to be an exotic - but I could go with a front mount, kind of like a baby carrier for my halfling. wow...

The mount evolution can not be used with a bipedal base form.

That's what SRD sites are for. or the SRD apps for your smartphone.

I will endevor not to overlook things in the future.

That said, and realizing that the book says:
"Mount (Ex): An eidolon is properly skilled and formed
to serve as a combat-trained mount. The eidolon must
be at least one size category larger than its rider. This
evolution is only available to eidolons of the quadruped
and serpentine base forms."
is there a way to use a Biped form as a mount - even a non-combat trained mount? My character concept is for a non-combat eidolon anyway.


so if the Summoner is medium sized, than having an Eidolon mount is out of the question at lower levels, as if memory serves me correctly, it was quite expensive to make a large eidolon. am i correct?

You need the Large evolution which I think requires 4th level, and then the mount evolution which you should be able to buy at that point. Then budget for whatever else you want it to do with the points left.


Summoners can't get Large Eidolons until 8th level. Before then the best you can do is use Enlarge Person on it to be usable as a medium Summoner's mount.

I think it goes strongly against RAI to use a Biped base form as a mount, even untrained. I don't think it's strictly against RAW though.

SO what's the difference between having a "mount" and being carried by a humanoid shape, assuming sufficient strength?

I'd assume you'd have limited options if you're in someone's backpack or on their back as opposed to you being mounted on something designed as a mount. Difficulty with drawing your gear while you're in a backpack or difficulty with balancing if you're not in a backpack. Stuff like that. I'd assume there'd be some mechanical drawbacks because they say Bipeds can't get the Mount evolution.

Actually, if you go with a serpentine build and give the eidolon a pair of legs, you could get something that looks very much like a kangaroo. You can't take the pounce evolution, but you can take Skilled (Jump) and max out the eidolon's Jump skill.

Just say it's against the rules and leave it at that. Otherwise you now need to go back and explain why a snake is "designed as a mount" and why a druid can ride a 2 legged dino but a Summoner can't have his Eilodon look like a kangaroo. Wait, can a druid ride a Kangaroo? never mind. Sorry I was trying to be different - I'll go back to riding the sorta dog thing.

Now this I like! That's what I like about this board. We're back on the drawing board now. A Serpentine with legs.... and I have no intrest in the Pounce evolution - that puts us in melee, where I never want to be.

That brings up just the most... odd... mental image... Picture a gnome or halfling summoner with a medium or large eidolon that he used as a mount from a position in a backpack... Pump up the eidolon with combat capability...

I think the sentence that reads "only available to serpentine and quadrapedal base forms" spells it out quite clearly.


Lvl 1:
Quadruped + climb + mount + X
You have a ground and climb speed of 40, seems good for a mount.

Lvl 2:
Quadruped + climb + limbs (legs) + mount
Now the ground and climb speed is 50, what is not to like?

From here I'd probably be happy to go with other classes more suited to making an awesome archer.


This thread has inspired me. I won't say how or for what, but know that I am inspired, and as a result a horrible horrible thing has occurred.

True, that rules it out in the "I'm riding on something" department. The question is more like "Is it against RAW for my 24 Str Biped to carry me around constantly in his backpack?"

Serpentine Base Form:
(Free Evolutions: Bite, Climb, Reach (bite), Tail, Tail Slap.)
(1st lvl Evo: Limbs, Mount, ???)

for the other 1st lvl Evo I'm thinking Scent or Skilled (Jumb) or maybe Swim... any suggestions?

what about feats?


Scent, Skilled (Perception), or Skilled (Acrobatics) would be good choices. Acrobatics covers Jump now. If you want Swim I'd just as soon consider the Aquatic base form.

Alternatively, I built a Halfling riding a Serpent Eidolon that was a functional Rogue:

Spoiler:
<Skill-dolon> (1st Level)

Form: Serpentine
AC: 13 (Base 10 + Dex 3)
Initiative: +3
Speed: 20 ft
Ability Scores: <Str 12, Dex 16, Con 13, Int 7, Wis 10, Cha 11>
Skills: <Perception(1)> +4, <Stealth(1)> +7, <Acrobatics(1)> +7, <Disable Device(1)> +7, <Diplomacy(1)> +4
Feats: Weapon Finesse (1st)
Evolutions (base): <bite, climb, reach(bite), tail, tail slap>
Evolutions (extra): Limbs(Arms), Mount
Attack Routine: Bite +4 (1d6+1) and Tail Slap -1 (1d6+1).
Notes: Halfling favored class bonus (or 5th level ability increase to Int) gives extra skill point. Maxes out first four skills and dips the fifth into useful skills. Halfling has Outrider alternate racial trait (+2 bonus on Ride and Handle Animal) and Wanderlust alternate racial trait (+1 CL on movement spells, +2 on Knowledge(Geography) and Survival). Expeditious Retreat compensates for slow movement. Mage Armor, a good ride check, and Mounted Combat from the halfling help protect the Eidolon from attacks, though admittedly not much at level due to short spell durations.

<Skill-dolon> (5th Level)

Form: <Serpentine>
AC: 19 (Base 10 + Dex 3 + INA 2 + NA 4)
Initiative: +3
Speed: 20 ft
Ability Scores: <Str 14, Dex 17, Con 13, Int 7, Wis 10, Cha 11>
Skills: <Perception(4)> +15, <Stealth(4)> +18, <Acrobatics(4)> +18, <Disable Device(4)> +18, Diplomacy(1)> +4, <Sense Motive(1)> +4, <Bluff(1)> +4, <Intimidate(1)> +4
Feats: Weapon Finesse (1st), Combat Reflexes (2nd)
Evolutions (base): <bite, climb, reach(bite), tail, tail slap>
Evolutions (extra): <Skilled(Perception)(1), Skilled(Stealth)(1), Skilled(Disable Device)(1), Skilled(Acrobatics)(1), Mount(1), Improved Natural Armor(1), Limbs(Arms)(2)>
Attack Routine: Bite +7 (1d6+2) and Tail Slap +2 (1d6+2)
Notes: With impressive skills, the Eidolon can make a good skill-monkey rogue, freeing up options for the Summoner and the rest of the party.

<Skill-dolon> (10th Level)

Form: <Serpentine>
AC: 28 (Base 10 + Dex 8 + INA 2 + NA 8)
Initiative: +8
Speed: 20 ft
Ability Scores: <Str 16, Dex 26, Con 13, Int 7, Wis 10, Cha 11>
Skills: <Perception(8)> +19, <Stealth(8)> +27, <Acrobatics(8)> +27, <Disable Device(8)> +27, <Diplomacy(3)> +6, <Sense Motive(2)> +5, <Bluff(2)> +5, <Intimidate(1)> +4
Feats: Weapon Finesse (1st), Combat Reflexes (2nd), Agile Maneuvers (3rd), Martial Weapon Proficiency: Short Sword (4th) Multiattack (bonus)
Evolutions (base): <bite, climb, reach (bite), tail, tail slap>
Evolutions (extra): <Skilled(Perception)(1), Skilled(Stealth)(1), Skilled(Disable Device)(1), Skilled(Acrobatics)(1), Mount(1), Improved Natural Armor(1), Trip(Bite)(2), Ability Increase(Dex, 2x)(4), Limbs(Arms)(2)>
Attack Routine: Bite +13/+8 (1d6+3) and Tail Slap +8 (1d6+3)
Notes: By this point there are some evolution and skill points to spare, so you can change a few evolutions to make it even more Skilled if your party needs a face. A good CMB and Trip on the bite helps control the battlefield. Medium size helps with practicality. Improved Share Spells with Reduce Person could also be helpful. Short Sword Proficiency gives a nice backup for damage, especially in case of DR.


Is third party stuff allowed? Because uh...these are awesome.

Yea, go ahead and be a gnome with a walking volcano that has a hut on it. Who needs optimality when you've got style.

yeah - I'll check the build out later when I have more time. I had thought about building a bit of rogue in, mainly for disable device. I'm still playing around with this (and it'll be character #6 or 7 for me.)


I made a goblin who's serpentine mount was a hover bike. I pump a bunch of points into the fly evolution and got him a 100ft fly speed. The high dex helps with AC and the fly checks. I also gave him arms and a crossbow. Lots and lots of bolts. Being able to move 100ft fire off a full attack +1 from the eidolon is so sweet. The skilled evolution is also great.


I don't think there is anything wrong with having an eidolon mount without the Mount evolution, especially if your Ride skill is high enough. Lurk3r pointed out in the 2nd post that the Mount evolution really only saves you 5 on a ride check, which is true.

The Mount evolution reads:
"An eidolon is properly skilled and formed to serve as a combat-trained mount. The eidolon must be at least one size category larger than its rider. This evolution is only available to eidolons of the quadruped and serpentine base forms."

So, it only makes an eidolon properly skilled as a mount. The requirement is that they have a proper form that allows them to BE skilled as a mount.

The ride skill has a clause that reads:
"If you attempt to ride a creature that is ill suited as a mount, you take a –5 penalty on your Ride checks."

Thus, improperly formed/skilled mounts can still be mounted. This means that eidolons may be mounted, regardless of if they have the mount skill or if they are even eligible for the mount skill. There is no reason that a Biped Kangaroo type of eidolon could not be mounted. You'd just take a -5 penalty.
