Do smoking kills, get a slayer helmet ASAP.
Use the highest master for your slayer level (Duradel/Lapalok for now)
Buy a black mask until you can make slayer helmets.
Get 68 summon for bunyip (Slayers best friend!)
Should of mentioned that is the first thing on my list and to mention I already have a Black mask.
Would you say to train 68 Summoning using a faster charm drop rate method or to just to train Slayer for now and save up the charms?
Just slay and get the crims I guess, shouldn't take too long to get 68 summons worth slaying constantly.
Ohyeah, and invest in a nice stock of super attack and strength potions - they speed up the training signifigantly (Assuming you can't make extremes/overloads)
