Could anyone post a decent guide on how to do QBD, I've never really tried her seriously but I've recently looked into making money off of her. Thanks in advance.

I don't think there are too many great guides for it to begin with, but the strategy page on rune wiki(not the utterly useless crappy one by jagex) is a good place to start. To me, what it all boils down to is:

a) do you have a t80 weapon(she is t80, so anything below you'll not be very effective against her)

b) are you any good at reacting to all the specials and can you use abilities effectively

 

If the answer is yes then and only then should you use it as a moneymaking method, otherwise you'll not kill her fast enough to be effective. Turmoil(and the mage/range eqvivalents) and overloads are also highly suggested for fast kills. As most of the damage you'd be taking is from specials, you will need to figure out what damage is effective to avoid and what isn't, ideally, you shouldn't use more than 8 food per kill and average less than 4- banking takes quite a bit of time and effort.

 

I think the most effective setup would be full void, dual ccb with yak and 2 bunyips and a champions tacklebox. This way you can get around 15 kills an hour and do over 36 kills per trip.

There are many good guides on youtube.

 

It is not that hard and can be fun. I started it to make a royal CB and found it very enjoying.

For me the safest way is ranging.

Also - it is very likely that you will die at least several to many times until you get it - don't panic, know where the gravestone spawns and it will be ok.

There are plenty of way to kill her as suggested by the many guides on YouTube.

 

In general:

Magic: SOL, Bloodfire Blitz (or better), Full Ahrims (or better), Mage cape, Seers ring, Glory or better. 1 super antifire, 1 super magic pot (or Venca Skull), 2 to 4 prayer flask, and food. A War Tort helps.

Range: Royal xbow with Royal bolts, Full Karil's (or better), Ava device, Archer ring, Ranging amulet. 1 super antifire, 1 super range pot, 2 to 4 prayer flask, food.

 

Once you learn her you can adjust as needed.

So Staff of light is accurate enough for QBD?

Mage is, in general, the worst style to use there so for moneymaking, i wouldn't really suggest it.

 

Also, one consideration here is that the drops have dropped dramatically, so you only make around 200k per kill nowadays, so getting only 6-8 kills an hour really isn't acceptable anymore(where as it used to be good enough to make 2-3m before).
