Companion
Starting at 1st level, you gain the services of a Wyvern/Pegasus/Horse, that you have raised and trained since it was born. It is friendly to you and your companions, and it obeys your commands.
In combat, the companion acts independently of you, but it always obeys your command. In combat, it rolls initiative and acts on its own turn. It can't attack without your command to do so, but it can take other actions as normal. You may choose to have it attack as a bonus action on your turn.
You can mount your companion. The initiative of a mounted companion changes to match yours when you mount it. You can only move to dismount your companion, while mounted.
It moves as you direct it, and it has only four action options: Attack, Dash, Disengage, and Dodge. A mounted companion can move and act even on the turn that you mount it.
When your companion is slain by a creature, you gain advantage on all attack rolls against the killer for the next 24 hours. If the wyvern dies, you can perform a special ritual to bring it back to life. The ritual is performed as part of a long rest to summon his soul and regenerate his body.
