From 22-31, make Granite Crab pouches. This is a fairly effective method, as well as costing little charms. It will require 1,300ish blank poucheswith gold charms RuneScape Gold, iron ore, and 10000ish spirit shards. This is likely to cost you in the mid, to high 200k.
From 31 to 40 you will make Vampire Bats. They provide decent exp and their materials are not so difficult than other. Take 170 blank pouches the crimson charms, and vampire dust, as well as 13,400 spirit shards. The cost is in the vicinity of 300k.
40-52, honestly, go with Granite Crabs. It's much cheaper than the other option, Bull Ants and it's difficult to find the marigolds needed for Bull Ants. For Granite crabs all the way you'll need 4,010 blank pouches, gold charms iron ore, and 2805 spirit shards. It will cost you from the 600ks to around 700k.
52-55 you will make Spirit Terrorbirds. Make sure you have these pouches, as they can be very helpful. 2,220 pouches that are blank and gold-plated charms as well as raw bird carcasses and 3000 spirit shards of glass are required. That number is a little of a mess. Head over to tip.it 3. Good Luck mate, and hoped I helped.
The setup currently I use for mage Buy RS 3 Gold, I am using: Helm of Neitiznot (Acctually provides a small magic attack and defenes bonus and prayer). Ancient Staff/Drag Dag P++/Whip (They don't in any way reduce the your magic attack bonus and I prefer to cast them manually while being in a melee position so I can keep them in place before I DDP++ Spec them or just whip)
