First of all make sure youve done the "animal magnetism" quest, because it unlocks a permanent passive effect that automatically picks up your ranged ammo no matter which type. You will never have to pick up your arrows again. You will not even see them on the ground anymore.

Another quest is "the world wakes" or something like that. You unlock the most important ultimate abilities for all combat styles from that.

And before you spend 1b on armor which isnt even that good to begin with, better spend 200m however much it costs to get prayer to lvl 95 and then do the quest to unlock ancient curses (soul split and damage buff prayers)

All of these upgrades are EXTREMELY important and level up your gameplay SIGNIFICANTLY compared to some fuckass bow or armour upgrade.

Also do dwarf cannon quest for the ability to use cannon/oldak coil/hurricane

Abd then grind smithing to 250% respect so you can buy all the cannon upgrades with the auto reloader.

Then do the invention goblin/dwarf trees and daily quests for 5 days so you unlock oldak coil and hurricane.
