Do you know where is the best place to buy OSRS gold?
In case you don't need to OSRS gold tank Supreme, don't attract a cannon (or if you do, then time your kills/placement perfectly so cannon just hits Prime or Rex (or Prime expires before Supreme spawns and visa versa)) and first kill you tank 3 (or only Prime/Supreme if Rex doesn't spot you) while praying mage/turmoil. After Supreme is dead you receive Prime to ~1/4 or lower hp (not too low or Deflect magic will ko, unless you're using normals to get Augury/Rigour, in which case get it to ~1/10 but make sure not to kill it). Then kill Rex and Prime fast as soon as Rex dies, then execute and kill Supreme before repeating.

This technique is much slower and, arguably, takes more preparation and you are far more vulnerable to crashers messing up your own instincts, but you should be taking no damage whatsoever except in Spinolyps, so for novices it tends to be easier, especially if you're not knowledgeable about the kings' max hits and when to flash soul split/etc.
You should not need a yak in case you've done the elite frem diary, however it is almost necessary if you haven't, otherwise you lose out to a massive portion of your gain and it is not even worth DKing at the first place, if you don't DK for pleasure not profit (like me).
In general, if you would like to be good at killing any boss, research and test out different approaches yourself. I seldom see anyone else using a titan in DKs, despite it increasing your kills/hr hugely, you can not charge the hides without amount pots either (because you kill the sins too quickly ) and having frem boots 4 signifies that if you bring friends it doesn't matter how quickly your kills are, you won't need to think about your yak scroll exercising.

Now, I'll explain why: RuneScape for a game is not able to copy mainstream MMOs because of the way the center of the sport works.
In Cheap RS gold, however, everything is tied to skills. You craft your gear, you level abilities, you train your combat level and you can not do anything significant without instruction skills. That's a simple fact, you can barely pursuit with no skills educated.
I'm not saying that is bad, but it leaves RuneScape somewhat crippled. Obtaining 99 at a skill on RuneScape is traditionally equally as quickly as attaining max character level in another MMO, for the most part (unless we are dealing with useless abilities like Cooking, Fletching, Firemaking and such that can be done in 60-70 hours complete ). Heck, if not more.
