Erazor Djinn
When fighting the Erazor stay in the middle until he attacks, then move to a side. Repeat until he slides the sword along the floor.

When he does the sword attack, try to anticipate which avenue his attack comes down on. Use the homing attack quickly (thrice) to continue to live.

Eventually the boss will strike three times, then vanish and quickly appear in front of you and strike along the floor again. If you see the pattern coming, you can respond with a jump and homing attack and defeat him easily.
