Is there any difference between finding rare items online vs. offline in PSO? I just went through the mines in VH mode offline and found all these rare items:

M&A60 VISE +2
M&A60 VISE +4
Ultimate Barrier
2x Divinity Barrier
2x VARISTA +2
VARISTA +4
8x DB's SABER
VISK-235W
CLUB OF LACONIUM +1
3x BLADE DANCE +1

I've played through the mines many times online and never found this many rares. So do you have a better chance of finding them offline than online? Am I extremely lucky or are these items not as rare as I think?
