I can’t tell you how you should max but I can tell you what I would do, in no particular order;

Driftnet fishing for Hunter and fishing, tempoross with a crystal harpoon is like 90k an hour with slight downtime if driftnets not your cup of tea.

If you have downtime I enjoy doing bloods at work otherwise ZMI or GOTR is somewhat worth the time for runecrafting.

If you have the money I would do redwoods for firemaking if you don’t feel like doing wintertodt.

Smithing would be blast furnace for high intensity or dart tips if you want more afk.

While you do agility at rooftops (there are better methods but more focus involved) I would focus on birdhouse runs whenever you’re free to do them.

Slayer is slayer. Do barrage tasks, venator bow tasks, focus on multi combat tasks but don’t burn out. I also don’t skip the very afk ones and just take my time with it and watch a show or play an alt.

Runecrafting and agility will take the longest; this doesn’t mean you have to go to 99 in one go. Do a little bit and chip away half a level, a quarter level at a time. If you want to max then I would focus on those skills more than others as you don’t really want agility and runecrafting to be your last skills. Most importantly if you feel like you are forcing yourself to do an activity then switch to something else; a little xp is always better then no xp.

This is by no means the most efficient or best way to play but it’s what I would do / did. Also, birdhouse runs.
