You can make money doing the following:
Cerb - Drops are from 15-35M on average (crystals/stone)
Bandos - Drops are from 25-35M on average
Raids1 - Most uniques are from 20-60M, with some being 90-160m, and TBOW 2B.
etc, just depends on what you want to grind/enjoy.
Thanks for the info mate. But that's exactly what I mean, each of those drops is like one in a hundred+ kills. Is there any boss where there's an almost guaranteed drop like every 10 kills? So you make much less from each drop but the drops are more often.
Barrows:
Ahrims and karils sell fairly decent for good price + alch + runes + random items.
Vorkath also has a very good drop table (Dragon bolts are like 2m/drop) and it has again good alch drops + pure gps.
Hydra same as the above + it has potential to drop a big item.
Cool beans, thank you!
