What should I need to have a Wyvern as a mount?
Mounted Combat, while useful, isn't actually necessary. Generally Persuasion and Deceit only work on intelligent creatures so Animal Handling is probably more appropriate, depending on the INT of Wyverns (ask your DM, since they are the final arbiter).Mounted Combatant is a must have, but Animal Handling is really necessary? Can I use Persuation, like using on a Pegasus, to calm and trainning them?
