Possible Perks

While any skill can be chosen for levelling, only a few have potential perks that come with having the higher level. As the 120 skills have a softcap of level 95 in Hard tier, only normal skills can gain any advantage.

Several skills can unlock a Player-owned port adventurer early with this task: runecrafting, construction, agility, thieving, hunter, divination, fishing, and cooking. That said, several of these skills see no other significant benefit to early levelling.

Construction

It is unlikely that players will be filling many master clue hidey-holes in Hard tier, but the upgraded marble wardrobe has no restriction on the number of items stored. This can allow you to deal with old gear sitting around and let you purchase things like the minigame outfits for easy passives without having to store them in the bank.

The biggest improvement that construction offers is the Player lodge, which can store a 99 skillcape for use of its perk at all times. This can be used for something like a defense cape, which lets you have a sign of life protection at all times.

Fletching
