Well, I'm PLD75 with a broken Subduer, but my 61~soon to be 62Drk needed a greatsword to go with my V scythe, so this is the best one i could find in the level range. So me as PLD75/RDM37 and my 63Drg/thf friend decided to give it a try.
Over the course of 8 Quus we skilled up on crabs and ghosts, then on Quus #9 he finally popped. i then flashed the Cancer and ran to the zone with 5 other crabs behind me and luckily no ghosts.
I had the drg poke the crab after i zoned to make sure it didnlt go anywhere, zoned back in, Stoneskin + Phalanx and flashed it off him and fought at the zone. As i watched his penta hit for 200 rather than the 600 it was doing to robber crabs i decided to invite a thf that was near by skill upping as well.
Even then it was a rough fight that would have been a wipe if not for Chivalry, this crab has waaay to much defense and hp to try and duo like this. But when it died we got 3109g and i am now 1/9 on pop, and 1/1 on the drop. Spirits within is your friend in this fight, 300TP plus self curebomb = ~590 damage.
After testing the greatsword on the lizards in zone the proc was about 1/8-1/12 swings for 39-49 damage additional. I'm looking forward to getting 62 on Drk.
