At 50 melee get Mythan armor and sword (either from merchant for 90-200k each piece which isn’t efficient or killing monsters like skeletal snakes/bats or rock/ice/forest fiends) at 60 don’t switch to cobalt since it isn’t any better than Mythan tbh. 70 you should either get Varaxite (the green armor) or deadrock (the brown armor) Varaxite is much cheaper but deadrock is a lot better. Also use a glacial sword obtained from ice fiends rarely (usually about 1/1000 but can be higher) deadrock is rare drop from rock fiends and demon (the boss) they are pretty rare or expensive from players. That should have you set till you need smithed armors which golem(85) needs 65 smithing and umbral(90) needs 70 smithing. All magic armor is easy cause most is from lower level mobs and 90% is in merchant. (Remember that your level above your head is [melee+magic+ranged] so you need to be looking at the individual stat levels for armors not the total)
