Get a party with 1 puller (Pld works well), 1 healer, and 4 jobs that can AoE (bst, blu, blm, sch, smn, etc)

Have paladin pull 6-10 VT mobs together into a pile and then everyone AoE them down.

If you do it well and get into the groove of it, its easy and fast Silt. I and my LS members average about 100K~120K Silt/hour. That's a LOT of tribulens.

If people got out of the "hurr durr Im gonna go into escha and solo with 5 trusts, man this is slow" mentality and actually formed parties like SE wants (you get a silt bonus for every party member you have) you would realize it doesnt take long at all to farm up a tonne of silt.
