Antipaladin help

[Seryph]

Playing in a Way of the Wicked campaign and working things out for the latter half of things. I'm playing an Aasimar Lord of Darkness archetype Antipaladin, setting up primarily for intimitank, then later jumping into mounted charging

I'm trying to find a way to get an Advanced Nightmare or Cauchemar as a mount. Fiendish Bond doesn't seem to allow it, and even with Animal Ally/Cavalier Dipping/Monstrous Mount it doesn't seem possible. Leadership doesn't seem to be too useful in that aspect either, since you have to be 13th to get a Nightmare (Effective Cohort level 11), which at 13th level, a 5HD nightmare is not likely to survive....

Only other option I can see is Planar Binding and hoping it doesn't kill me. Things are still fairly early in the game, and I'm not terribly opposed to dipping to get this, just nothing too extreme (a couple level dip into cavalier is probably in the cards anyways).

It just seemed that an antipaladin rocking a nightmare just needs to happen. No 3rd party feats

I wrote a guide a while back on the class.

There is the Monstrous Companion feat. It alows you to take a pegasus as a cohort, and a Nightmare is thematically similar on the opposite side of the alignment scale.

I would talk to the DM about using that feat.

I am gm'ing Way of the Wicked and you may get an opportunity to acquire a Nightmare between 6th and 10th level. Consult with your GM before making too many other plans.
Failing that get your caster friend to Planar Bind one or call a contract devil to make a deal for a nightmare
