My personal favorite skill would have to be woodcutting. Although, for one of the more faster skills i would suggest cooking as i have heard of some people getting from 1 to 99 in about 12 days.
Well, it depends on the method you use to get the 99. Normally the method that makes the most money, takes the longest time. Here are a few with methods and approximate money and xp rates. I will specify member and F2P options.
Fishing- Members Method:
Fish in Shiloh village (Fly Fishing) to level 85. Requirements: Shiloh Village Quest
Then fish cave-fish 85-90. This will make approximately 8 million gp.
Then fish rocktail to level 99. This will make about 40-50m.
Fishing- Non-members method:
Fish at Barbarian village 30-99
This is about the best method. You can mine runite to 99 and that will make more than 1 billion gp! Yes 1 billion! But that would take a long time!
Id probably say woodcutting....or maybe runecrafting?
any level you just have to have 99 of that skill.
Yes? You still can use the skill, even if it is at level 99, the level cap for Runescape, except Dungeoneering.
That depends entirely on what skill you are raising.
There are farming calculators out there, and depending on your level and what you will be using to level this skill up you can get the price of that item and times it by how many you require for this answer.
The Answer will depend on your skill stats. Level 75 doesn't necessarily mean you can cut Yews or cook Swordies.
you cant
If you go on runescape highscores, you can see that lots of people have 99 skill level in everything. Every single one of these players will have all the skill capes
no you just need to get to level 99 with that skill
There are many ways to get a lot of money, fishing is a good skill to make money in, slayer is as well and just all out killing monsters makes good cash in the end
you will need a total off 7,842 exp in that skill.
You should have around 737,627 Exp by the time you are level 70 in a skill.
463,885exp
