Arena Tournament, Round 49: Kor Battleborn and MitS vs Leaf and Cyn

[Morbius]

I sketched it out to verify angles and such....

The hippogriff takes its turn on Leaf's initiative so it gets a double move. Leaf's ready action altered his initiative, so it acts now.

At speed 100' (double move, half speed while climbing), taking off at 60 degrees it could have gone 50' forward and 85' up. In this case it leveled off at 75'.

Does that work for you?

I don't know if it could use a double move on a readied action as you can only ready standard actions or faster and a double move usually lasts one full round, even if you are not the one moving. Indeed the mount share your initiative but in this new initiative you can only take one action this round
