Mining rune. I haven't mined it in several years since they dramatically reduced the amount of f2p worlds. A month ago, I mined rune at the lava maze. Sometimes, I hopped to planets with f2p and discovered that around half of RS gold the f2p universes included Pkers. The lack of a kbd lir makes it a real hassle. You have the option to kill them (if you're very early in your adventure) or to run your way to the wilderness (20 in the wilderness). Lots of competition in the mining guild resource dungeon, but it might be more enjoyable than wilderness. I'm sure I've missed certain areas, but I did post an extensive list somewhere, but that was in June of last year.
The Defence pack will drop you at level 1. But your level should be greater than 10 in Attack Strength, Magic and Attack. This is a OSRS buy gold very abused system. This means that anyone could change into a pure maxed with 1 defense if they have the maximum combat.
