AI

The AI (or artificial intelligence) is the behavioral pattern exhibited by an NPC. For instance, the Caster AI will always teleport, shoot 3 times, pause for 3 seconds, and then teleport again. Knowing which AI an enemy uses can present an advantage in a fight, as it offers an idea of how the enemy will attack and react in given scenarios.

Though many enemies have their own AI pattern additions, like friendly mode of surface slimes, encirclement of Eater of Souls, speed up of Wandering Eye or ranged attack of some Fighter AI mobs from 1.1 patch.

There are 21 different AI types:
