If you want a op fleet of wyverns read this.

First, tame about 10 wyverns (Tropical or Ember recommended) and beef them up to about 10k health if you can. Here are the priorities you have to make for the stat points.

Health always comes first so they can last longer

Then stamina so they can fly longer and fight longer

Then melee damage so they can do tons of damage.

I also would recommend a blood wyvern since they drain health easily. For a blood wyvern do health, damage and then stamina.

I hope this helps! Thats how to make a op wyvern.
