You shouldn't need to have a yak as long as RuneScape gold you've done the elite frem diary however it's necessary if not otherwise, you'll lose an enormous portion of your profit and it's not even worth to do it in the first instance, unless you DK to have fun and not earn money (like my case).
In the end, if you're hoping to master the art of killing anyone, do your research and test various methods to test your skills. I've never seen anyone else using a titan at DKs however, it can increase the number of kills per hour dramatically, but you won't be able to cash in the hides without sum pots (as it kills the kings way too quickly) and having the frem boots 4 allows you to play anyone you bring along isn't a matter of how quick your kills are, and you won't be concerned about your yak scroll expiring.

For those who claim they believe that RuneScape is trying to WoWify itself: Stop being so sure, you're not. In this article, I'll show the reasons: RuneScape as a game is unable to copy mainstream MMOs due to how the game's fundamental system operates.
In MMOs that are most popular, you are able to increase the level of your character before you can level your character "skills" are traditionally just jobs and things like that let you create, alter and boost certain things, or yourself. In RuneScape, however, everything is linked to your skills. You build your equipment or level up your skills, you build your combat proficiency and buy OSRS gold are unable to perform anything else without acquiring the necessary skills. The fact is, you cannot even get a quest going with no skills trained.
