Guide to killing Nomad from Nomad's Requiem

I've been battling various bosses during the last 2 days. A lot. With marginal success...

• Made two more visits to Jad (no luck...)
• Finally did the Blood Runs Deep quest and defeated the Dagonnath Mother from the third attempt (first I forgot death runes... then I ran out of air runes during the battle...). The quest was beautiful, by the way. Beautiful and sad. Did they have to kill my wife? Did they really?!
• And, of course, I bumped into Nomad. About 8 times... And only once I got to the berserk stage. I don't think I am close to winning there yet. Well, at least he does not heal on me anymore. But I am running out of supplies: 5-6 more tries and I'll have to postpone the whole thing.

Found a few good guides on how to kill Nomad (as expected the started to appear). This is probably the best written one and below is a good visual illustration to it. Good luck, everyone, no matter what they say about skillful clicking, luck is definitely needed in Nomad's presence.
