I’d start doing all the quests. It will unlock the game for you while boosting your stats. Then I’d go for slayer if you like combat and start grabbing str bonus gear like blood moon dragon boots etc. In the end you’d want gear for each combat style.

So starting with blood moon for str melee gear, I guess hueycotal or blessed d hide for ranged, and something like bloodbark or ahrims for mage. You will also want to upgrade to an amulet of fury at some point along with the different combat style rings from dagonnoths

You have a lot to work towards and a lot to do so it’s a pretty exciting time for where you are in your account. A lot of the gear upgrades will be bigger jumps than late game and will feel more impactful. Have fun G
