Here's some material which is useful for mounts but is unlikely to be allowed in a standard game:Awakened Animals: Dragon Magazine #293
provides ECLs for every creature in the 3.0 Monster Manual, including awakened versions of animals. Note that some creatures which are Animals or Magical Beasts in 3.5 had the defunct "Beast" type in 3.0, monsters didn't have a consistent number of feats per level (by the conversion rules you add more if there's too few and convert some to bonus feats if there's too many), and Awaken didn't change the type of animals it was cast on (while turning plants into Constructs).Valicorn:
A "half-unicorn" template for any equine animal or awakened version of the same, from the web enhancement for Ghostwalk
. It's listed here because it's unquestionably mount-related, but there's no legal way to buy one, play one or attract one as a special companion. Still, it's only CR +1, so you might be able to work something out with your DM - in particular it seems like a reasonably thematic upgrade for a Valenar Riding Horse if you use one.Bone RiderTome:
A PrC that gets you a kickass undead mount which can be combined with your cohort. Since this is part of the Tome rules, you're much more free to use any monster as the base
. I recommend an ooze or something, since it gains an Int score and you're immune to negative effects of being in its presence.Fey druids:
Leader of the Pack feat is of special note, doubling the effects of bardic music on your animal companion. Fey Blood feat reduces MAD in some builds.Mighty Steed:
A feat found in the Dragonlance supplements Bestiary of Krynn
and Knightly Orders of Ansalon
. A mount with this feat counts as one size category larger for determining carrying capacity and the minimum size of its rider
. That is, it lets a Medium character ride a Medium mount, and lets a kobold with Slight Build ride a pseudodragon.Pathfinder
- Archetypes (animal companion): Totem guide is the most interesting of these, particularly in the hands of a character who can't access its spells normally. They add new feats to those the animal companion can select, but they weren't restricted in the first place so just ignore that part.
- Archetypes (familiar): Valet is the only one of these that's any use for a mount.
- Mammoth Rider: A PrC that advances animal companions and grants them extra bonuses. Can be pretty nasty, but note that animal companions work differently in PF.
- Trick Riding: A feat that upgrades Mounted Combat. Not bad. Note that due to differences in skill systems, it would require Ride 12 ranks in a 3.5e game.
- Undersized MountACG: A feat that lets you ride mounts of the same size as you. Combined with Mighty Steed, it lets a kobold ride a psicrystal (provided he can buff its carrying capacity).
