I'm having trouble dealing with MacroX boss. Any hints and advice will be very much appreciated.

1. His red magic missles are ok (I guess stacking 70% magic resist will do) - please correct me if I'm wrong.
2. His rainbow-color basketballs are incomprehensible

3. His 1 shooter are unavoidable if I stay in 3/4 of the radius - stay in the center and I'm dead for sure.

4. And not to mention that he is a caster so it's hard to identify him among those clones when you have to aim (except when he blinks on you and he shows a mark above his head).

5. Last but not least, I managed to take a potion of his health and he immediately heals up in 1.5s. So I am still unable to figure out how to defeat him yet.
Thanks in advance
