Wind blast and water blast or too much with death runes, i strongly suggest using any kind of bolt, depending on your enemy. It is mildly priced right now, its worth it but blasts arent for your lvl

By using the highest level spell you can. Higher level spells give more experience.

A Ruby Amulet in RuneScape can be enchanted with a Magic Spell that requires 1 cosmic rune and 5 fire runes to cast. The Magic Spell is called "Enchant Level 3 Jewellery" and requires a magic level of 49 to cast. All you have to do to cast it is select the spell in the standard magic spell book and select the item you want to use the spell on in your inventory.
Make some money on the game and spend it on some runes, and cast the spell you can cast and you will get magic xp for casting it on enemies.
To smelt with superheat you need both the magic level for this spell, and the smithing level for the metal you want to smelt.
The strongest Magic spell is Ice Barrage ( Level 93 Magic ), This will freeze the targest for around 20 seconds whilst dealing 28 Max damage at the same time.
Purchase runes and cast the highest spell you can.
You will get 48 experience for each Falador Teleport cast. You need a Magic level of 37 to cast the spell, and you can't cast the spell past level 20 in RuneScape's Wilderness or if you have been teleblocked by a player or monster. On the other hand, the Falador Teleport on the Lodestone network will grant you 0 experience, but it also free of charge.
Fire surge (requiring lvl. 95 magic)
In Runescape, You receive 65 Magic XP for every High Alchemy spell that is cast.
it sounds crazy but try this i am a level 40 so try this the first spell in the book with attack first wind strike
That is "telekinetic grab". Look in the spellbook. You need magic level 33. Once you have that, you need law runes and air runes to actually cast the spell.
