A tense fight, but very doable as a RDM47/BLM23. I took out two Thread Leeches to build TP, then fully buffed (Stoneskin, Phalanx, Blink, Enthunder, Aquaveil, Refresh, Ice Spikes) and touched the ??? with almost-full HP and MP.
Immediately after the leeches spawned, I cast Sleep II and Sleep on two of the leeches, and started engaging the third.
The next several minutes consisted mostly of me chipping away at one leech at a time with Beestinger, while keeping Sleep II on the leeches and buffs up. For insurance, I Converted after the second leech so I could take the third leech without any worries. Cure II was my main heal, plus Drains. No nukes were used, save my final Aero II to finish the third leech in style.
My assessment? {Easy Prey}
