I've already said it twice, but I don't remember the exact time frame (though I really want to say it was between late '02 and mid '03). However, what I do remember is:
1. During the period in which I was farming the Fungi Tunics, they were still extremely valuable or I wouldn't have been wasting so much time doing it.
2. The camp was extremely difficult. Every time I managed to kill the King I was always near death, too. I distinctly remember a few times where the fight came down to the last swing or three.
The hardest part really wasn't the King, it was breaking the spawn up and needing to stagger the death of the surrounding shrooms so they didn't respawn and kill me or heal the King. A respawned shroom while I was engaged with the King was an immediate Escape or death if it was on cooldown.
I was very well-geared rogue (I always was until I quit) and I maxed every worthwhile AA. Still, things had to go absolutely perfectly or I'd have to use Escape and try again. I still died more than a few times despite using every-single-tool I could get my hands.
1. Locustlure. 35% slow was huge and the camp wouldn't have been possible without it. I had a Willsapper too, but the slow on that weapon seemed to get resisted more. I can't remember if the Spinebreak slow poison existed at that time, but if it did, I would have used it if it were better than the weapon procs.
2. Stanos' gloves (30% click haste) on top of my 40-something worn haste item.
3. Poisons.
4. Kilva's damage shield potions as well as several other sources that stacked.
5. The HP/AC/MR Resist buff from Stanos' BP.
6. Primal Weapon for Avatar buff then I would swap to my better weapons. I'm 99.9% sure I was stat capped, but the 100 atk from Avatar was delicious.
7. As much in-combat regen as I could muster. Pre-nerf Fungi Staff, Dain Ring (10 Regen/10 Damage shield) for one. I don't remember how high I got it, but it was enough to provide a few hundred hp over the duration of the King fight. Significant for the time.
8. I know I had a few clickies that gave me more weapon procs. Symbol of the Planesmasters and Timestone Adorned Ring were two of them but I don't remember what else I had.
9. Mrylokar's gaunts to pull with dispel on mobs that were damage shielded (or whatever other dangerous buff).
10. Mrylokar's beastplate for the click heal I'd use to reduce downtime. It had a much better hp-per-second click than the 'upgraded' bp that came after it.
11. Nightfall (dagger) for snare. (no longer drops in the version I have).
12. The usual stuff like Jboots, Shrunken gob earring, all 5 flowers of functionality, Lodi boots, Blood Orchid Katana, Shield of the Immaculate, Pegasus Cloak, Tiny Cloak of Darkest Night, etc., etc.
I had a bunch of other tools and consumables that I simply can't remember. Despite all that, it was still incredibly difficult.
Something else I don't think you, and the couple of the other skeptics, have taken in to consideration is, at that time, I was on Stormhammer (in Township Rebellion). That server had a completely different economy than regular servers. The population was much, much smaller and very top-heavy. Everything was considerably more expensive. Also, the typical plat farmers didn't really exist for a couple reasons. The server had a low max capacity and the GM presence was constant so the farmers got banned relatively quickly.
I also think the server's demographic was more willing to spend money to get what they wanted, when they wanted it.
