Here is my guide for making a 50 attack 52 prayer pure, this will end you up at around 69 combat:
Start with manually doing tut island, doing quests manually also goes a long way to helping prevent bans imo, although if you want to bot quests stealth quester is your only choice here.
Start off with waterfall quest, then do death plateau, vampire slayer, and fight arena in that order. You can get your mage up before doing fight arena, will make it a lot easier. Then go for grand tree, tree gnome village and lost city. Then you should go do alfred grimhand's barcrawl miniquest and Horror from the deep for the god books, i recommend getting a full zammy book before training.
Depending on the prayer level you want, do restless ghost to get the ghostspeak amulet, then go and do preist in peril.
Bot 1-10 range at goblins, 10-40 at barbarians, 40-50 at sand crabs. Grab mithril darts at 20 ranged, use the highest level ranged armor you can afford and use. Then complete priest in peril, restless ghost and animal magnetism to get ava's accumulator.
Do 50-60 ranged at sand crabs.
Do MM up until you point you get the thing that turns you into a monkey, then don't do any more of the quest so you can always get back to the island. Chin your ranged up to 85 on the MM island, if you approach 84 hp, start cannoning ranged at the rangers guild on ogres.
Complete plague city and biohazard quests at some point along the road to unlock ardy teleport.
Grab a rune scim and go to sand crabs to 50 attack. I use APA Sand Crabs for sand crabs. Use a combat calculator so you can stay around the combat level you want.
Then get 80 strength from sand crabs, you will be using a rune scim the whole time.
Get 50 magic using any method, do desert treasure's prereqs, go kill the ice queen at white wolf mountain for ice gloves, then complete desert treasure for ancients.
You can use any method you want, personally I autoclick alch, but get 85 magic. This allows you to use teleblock and ice blitz.
Use dragon bones or dagannoth bones on a gilded altar (safe) for more xp, or use them on the chaos altar in deep wild for even more xp, beware the chaos altar is in multi so don't bring too many bones at once, there is an unnoter npc there who will unnote items for a fee. Get 52 prayer.
At the end your stats should look like this: 50 attack, 80 strength, 1 defence, <84 hitpoints, 85 ranged, 85 mage, 52 prayer.
