Scales are going back up so imo so will the drops. They are pretty cheap atm.
For setup i find void mage/range with occult, fury, god cape, avas, trident of swamp, blowpipe(i used mith darts for the most part but past 300~ kills i been testing steel darts and they dont seem that much worse), snake boots, malediction ward a cheaper/better set up to use. Less switches = more food and i seem to get better runs with void. This could just be bad luck from the little time i have used ahrims tho
