Before we get started, if you feel I left anything out, let me know and I'll add it in.

Here's a pic of my gear while not on a slay task :
And while on a slay task:
Professional inventory:
The obsurd amount of prayer potions will let you stay there for a LONG time, if you have the patiences to camp there you can easily get over 1.5k crimsons a trip.
Also, if you have soulsplit/turmoil I recommend putting them both on quick curses, and flicking them, if you don't know what flicking means here's a video demonstrating: [video=youtube]http://www.youtube.com/watch?v=t1V4iTiC8lQ&feature=player_detailpage#t=94s[/video]
Sorry for the song, just mute the video.
The welfare portion.
Slay task gear:
If you don't have fire cape, bring sw cape, legends cape, obby cape, etc. No barrows gloves? Bring whichever rfd gloves you can if you have rune or better, if you don't have at least rune rfd gloves bring a combat brace. Ring of life is swappable with berserker ring, or ring of wealth. Not on a slay task? Just bring a neits instead of the slay helm. You can also swap the zamorakian spear with a verac's flail if you're that poor.
Welfare inventory (assuming you don't have soulsplit, nor the money for excessive prayer potions):
If you're on prayers (not curses) you can pray range, and flick piety, or flick range prayer, flicking both of them isn't entirely effective because you and the waterfiend don't always hit at the same time. re-pot at around 110, find your own comfortable pace.
