How to ride a Medium eidolon

[Ravingdork]

I want to ride my eidolon. Unfortunately, it's Medium. How do I make my conrasu Small so that I can ride be carried around by my humanoid knight eidolon like a potted plant?

[HumbleGamer]

Get the conrasu killed and spam reincarnate over and, over until you hit a small ancestry.

Doesn't work of I can't look like a small houseplant.

Suppose I'll just have to play a leshy...

Is it PFS?

Because if not, a DM may allow you to play a small conrasu ( if you don't pick feats which requires, or advantage, you being small, I see no real issues between S and M size).

Alternatively you can reverse role ( leshy + construct instead of conrasu + plant).

The idea was that of a knight that carries a potted house plant.

Everyone thinks the knight is the adventurer and the house plant a mere oddity, but in reality, the opposite is true.

If starting at level 1, Leshy would probably work out better.

At level 8 you can get both Steed Form and Hulking Size and be carried around by a size Large knight.

And if you are using this as a ruse or something temporary rather than a permanent thing, there is 2nd level Shrink for 5 minutes and 3rd level Evolution Surge for 1 minute.
