How do you get mage up fast in runescape?

Answer 1

If you mean "getting to level 99", that won't be fast for any skill. Some ways to train magic are:

• Use magic in combat. For example, if you just do a lot of slayer task, you'll encounter lots of monsters that are weak to magic, so it is convenient to use magic in such cases. (You should also use melee and ranged combat in Slayer tasks, depending on the assigned monster.)
• Do lots of high alchemy. Fairly fast, and you can actually get a small profit - but this is also very boring.
• Train in the Mage Training Arena. Here you do four different activities - and here, you can also get some profit.
