Note 1 - Ranging potions can be acquired pretty quickly on OSRS at a low level from Tarn's lair, which isn't a thing here.
As a maxed UIM on osrs i have never had to kill tarn for dwarf weed. Seeds dropped from nechs + kurasks (1/31) should really be enough alongside cox honestly.
Support because other seeds/potions are easier to get on here via other methods too though. (compared to osrs)
