This is a simple Agathion code that I made a few days ago for aCis 405 and 401, it can be used together with pets or summon, and mounted on strider/wyrvern
It is summoned or removed with the same item of the agathion or any item that is linked to an agathion. It can also be summoned through an ability. It's support only, you can use any npc/mob with ability, for summonitems it must be an instance of Agathion
Here is a video of my implementation in aCis 405 with summonItems

and an example using the wolf item and another with a skill 7030

new changes added a setting to just follow the owner without any extra action, also for the social action, and another that can be set to heal the owner and at the owner's health percentage start healing him.
