After leaving when EOC came out (mostly due to lack of interest), Ive decided to come back to the 2007 version.  When I played in 2007 myself, I was f2p, so I never did things like slayer. This time around Im looking to do a lot of slayer, but I am at a bit of a loss as where to start at such low levels. Any advice or pointing me in the right direction of a guide would be most welcome.

Depends, what your combat stats are and what gear you currently have.  Anything you need for beginning slayer can be bought from any slayer master,and if you don't know something about a slayer monster, just use tip it or wiki or whatever you want to for the info. Best slayer master to start with would be in the Edgeville dungeon, minimum 40 combat required or the one in Canifis that requires 20 combat. 3rd one to use but requires some questing and level 75 combat is in Zanaris. If you have any questions feel free to add me in game and ask away!
