I've killed over 10k, no chain.
I spent a few weeks just training and got tons of rune arrows, fair bit of nature tallys, lots of herbs (Mid to high), rune daggers (alch), red vamps (alch), earth b staves (alch), half keys and maybe a few other things.
I was using sharks and Still came out ahead. (Especially since I Fished them all but meh

you can still come out ahead with buying them)
You don't need to use sharks, swordys or lobbys are fine.
Here's a list of suggested gear to use:
Facemask (Must wear at all times unless you want a free trip to lumby)
Gnome, glory, or fury
Legends, Obby, Fire, or Accomplishment cape
Barrows or rune plate
Barrows or Dargon legs, Rune are fine but have less defence
Dragon square or crystal shield (Obby and defenders are pointless, they give hardly any def in comparison to the above and seriously, does +5 str REALLY make you hit that much higher?)
Any weapon
RFD, family crest, or Black d hide gloves
Rune boots or best melee defense boots you have
Ring of Life or Wealth, or Dueling if you bank at Shantay (not the closest bank though)
You basically want melee defense, Obsidian and Rune defenders are not good shield for fighting dust devils because there defense is worse then a rune kite shield, and they give mainly to range, Dust devils attack via melee.
The Closest bank is Nardah.
They're good training and good drops, they don't hit too hard(8 max) but don't underestimate them. Also, as I'm sure you know, they require 65 slayer and a face mask at all times.
