O.k.
* Don't forget to equip the silver stuff instead of the flame sword/battle stuff.
* I equipped the power ring, because I thought, the sooner he dies, the better.
* Weared the mask of eyes; It reduces the holes in the ground by 1/2.
* Try to predict his track, and when you hit him, run along with him as long as possible, so you hit him more than once, and this way you avoid the holes at the same time (because you keep moving).
* The hardest part: Don't just keep an eye on himself; Try to watch the projectiles. Most of them are directly aimed at you, so keep moving, one step up or down is usually sufficient to dodge the burst.
* You also need some luck. Plenty. Oh yeah.
So, good luck!
