General Changes:

There are now AI for all four characters.

The mage AI is the same; it does everything randomly and it is still the hardest AI.

The monk AI is the second hardest AI and it tries to hunt you down and use its kick. It never uses Thousand Palms because it's too risky for an AI.

The caster AI is the third hardest. It moves randomly and tries to control you using its attacks.

The rogue AI is the weakest. It tries to hunt you down but it's really difficult for it to land its Rend.
