1-40
Go to Ape Mountain, players refer to this as AC (Ape City), as someone to power level you (power level). Hopefully someone will. If you leave or cant find someone to power level you. Go get a wand and a sword or club. Level the proficiency on these, so that you don't screw yourself by having to use weak weapons at level 40. Keep trying to get power leveled, u will eventually.
41-58
Now I recommend you go level yourself. Get your shield and weapon (plus wand) and go out to level. I recommend u keep your wand normal, something cheap, because it is only used to 1 hit monsters when you have superman, only equip it during superman, when superman is over, equip your shield and 1 hand back. This method will allow u to kill a large amount of monsters with 1 superman, allowing you to level quickly.
59-65
Now you need to hunt a little. Or, use the money u have from other char or being power leveled to buy elite Armour. Then I recommend a uni weapon (don't buy any refined, they are a waste of money). Now continue with the method you are using to level from 41, but be careful. You will take a large amount of damage.
66-70
This is the hardest leveling. You are not able to get 10 superman kills and gain a percent anymore. Also sand elf/ sand monsters attack high and have high life. I recommend you start + you items, only + elite items, its cheaper. If you play right, and hunt enough, buy enough elite, + enough items. You will take very little damage and be able to save you money from not buying pots. ALWAYS have a scroll. Just in case you find a met or other good item.
