J.U.S. AI - Divine Link
The AI is still being developed.
The Divine Linked pet's Defence increases a lot, so the AI aims to aggro as many enemies' attention as possible by using normal attacks.
It was based on Flora, so it's a good idea to use a pet that has similar stats and movement speed as Flora.
As a tip, it's probably a good idea to invest in Auto Defence sub-skill in Divine Link, to aggro the enemies.
J.U.S. AI - Range Supporter
It's a supportive AI for ranged classes, such as Firebolt Mages, Archers.
All patterns are to use Firebolt to support owner, it opens more distance for Firebolt Mage and gives more time for Archers to aim.
J.U.S. AI - Lite
It's a light version of J.U.S. AI.
Pet does not take action even when attacked, until it is knocked down,
it does not run upto an enemy when owner's preparing a ranged attack.
It is designed for those who don't like their pets using normal attacks too often.
