For those that are having difficulty with the berserker form or are running out of supplies, here's what I did: I ranged the whole way with ruby(e)'s and void, using a tortoise to pack a total of 11 super restores and 33 sara brews. After my tortoise was empty, I summoned my fire titan. I have 81 range, 87 hp, 80 defense, 78 prayer, and 79 summoning. I used curses - all usable leech prayers were active. After the fight I had 3 brews and 1 restore remaining. The entire fight I hung to the pillars, running behind one when I wanted heal in larger amounts (and running back immediately after he says "Face me!" - you don't want to restart) so as to prevent avoidable damage. Downing several pots while he's still hitting you can negate the healing completely, so make sure to do this. Also, let there be no squares between the two of you. Though he may still be hitting you, he WILL reset if you aren't standing directly next to him after he's given you the "Face me!" warning. A special note: when he "tests your senses" with the four illusions, take advantage of that time to hide behind a pillar and heal up. Drop your vials, withdraw from your BoB, etc; do all of this now as you have plenty of time. He will not "reset," though he will eventually revert back to single form and run towards you. You will get the "Face me!" warning, so no worries. Once I'd reached his berserk form, I semi-safespotted. I ranged him when he was stuck behind the pillar and would occasionally run up next to him and back to keep him from "resetting" to full hp. This prevented me from taking a lot of extra damage. If you have a titan, let it assist you in attacking Nomad while using some of its scrolls too - the extra healing and damage really help. Good luck.
