lvl 90 meteor static sorc HCL exactly 411mf i do meph with ease(hell ofcourse). In anywhere from 40 sec to 2 min. If durance is just vast and sparkfist isnt in a good place takes me as much as two min. Shortest time i have done a run was like 38 sec.

I have a hard time beliving what this guy is claiming he found in 8 hours.
I have more or less done 1000 runs on meph and yet to find an IST or a Shako or an SS.
But yes meph can drop nice things, just not all those in 8 hours.. unless there is a magic MF amount that generates WHOA drops.
