Combine them and
OSRS gold you'll be able to power-up! It means that you'll be using the most effective att/str boost prayers and super pots for your missions, and even a cannon is also an option if or can afford. You can earn over 100k exp/hour in more advanced levels. This is just as high or higher than armoured zombies and bandits. And you'll avoid appearing ridiculous like a 138 with a 70 slayer.
Gear should be: Barrows gloves, from RFD. Dragon boots. Full slayer helm, black mask until you get it. Armour Proselytize when you use prayers, and barrows in the event that you don't. Whip, try to get a chaotic rapier as soon as you are able to. Dragon shield, antidragon for jobs involving dragons (DFS is not enough, so don't use it.).
Amulet of fame, try to find one when you can. Ardougne cape 3, or the soulwars cape. While it sounds interesting but wouldn't it defeat the purpose of slaying? Part of the fun of learning Slayer is learning new ways to finish every job, and that's sure, fine. But why isn't it also an opportunity to earn money? I'm fairly certain that one day prayers could increase prices to the point where I'm losing money, would it not?
And thanks for your advice to all. Even with prayer potions , one will probably profit from slayer which are relatively cheap. With just the drops you will make money, and if you don't have that then you can purchase Slayer Dart Runes from the slayer master for 35 Slayer points (you get 36 for doing 2 tasks through Kuradel) costs you about ~70k which is decent and could earn some substantial cash if decide to spend the money instead of rescheduling or blocking tasks.
Can i train on bandits already, or should I go with Giant spiders in the stronghold until 70 def, then change to
buy runescape 3 gold bandits? Sumona demands 85 combat as well as Smoking Kills which you should do when you're a slayer.
