70m short of decent gear? Whip, rune defener, dragon boots and of course the slayer helmet are the only essentials. You can wear welfare gear in nearly all the other spots without compromising a lot on speed. (full bandos + fury + fire cape + zerker is not that much better than rune/barrow/dragon/granite legs/plate, glory, SW cape and warrior ring). Knowing this, you can get very decent slayer gear for under 10m. Bandos and DFS are far overrated. You are 300m short from the real slaying though (turmoil, soul split and extremes); but that is not an issue of gear. 70m more would get me enough to piety/super set each task, fury, zerker, zs, full karils, d boots, slayer helm, full bandos and perhaps dfs. Those are the absolute minimum for slayer, iirc. Lol no. Zerker and zs are not requiered for slayer. Neither is bandos or dfs. They are incredibly overrated. I have gone 1-89 slayer using dharoks top+bottom, d boots, warrior ring, slayer helm, whip, rune defender etc. It will cost much less than 10m and will be more than enough. And you shouldn't be piety'ing every task. Super sets are minimal though. You will still profit it you use them.
