Neo Khidr is a upgraded version of the first boss Khidr. In oder to beat this bos you'll need to become an expert at dodging.
Neo Khdir has three attack patterns:
The First one is a spiral one that can go in eihter direction, the second and third ones are a evenly spread and a random spread burst pattern. The spiral pattern will at first appear to be the most difficult one but can be dodged nearly every time once you get used to them. The second and third pattern are the ones you'll have to look out for.
Expect to retry this fight many times.
