Magic API

The Magic API allows you to interact with the magic book and spell casting within OSRS

Cast

Firstly, find your spell from the relevant spellbook.

Magic.spell.X;
ArceuusSpell.spell.X;
LunarSpell.spell.X;
AncientSpell.spell.X;

To cast, simply call the .cast() method from your spell. Something to note, if the spell has multiple options such as the Camelot spell you can pass in the action you want it to perform

Magic.Spell.HIGH_ALCHEMY.cast();
Magic.Spell.CAMELOT_TELEPORT.cast("Cast"); // this confirms what option you want to select
Magic.Spell.CAMELOT_TELEPORT.cast("Seers'"); // this confirms what option you want to select

Checking if the spell is casting

You can check if the spell is casting by calling the casting() function which returns a boolean if a spell is casting

Condition.wait(() -> Magic.HIGH_ALCHEMY.casting(), 50, 100);

Checking if a spell is castable

You can check whether a spell is can be cast by using the canCast() function call.

boolean canCast = Magic.Spell.ENCHANT_LEVEL_1_JEWELLERY.canCast();

There are some other methods available too for you to explore and use at your own pace.

Cast a spell on an npc

You firstly have to select the spell with cast() and then once you've confirmed you're casting() it, you can then interact with the npc.

if(Magic.Spell.FIRE_BLAST.cast() && Magic.Spell.FIRE_BLAST.casting()){
    Npc goblin = Npcs.stream().name("Goblin").nearest().first();
    if(goblin.inViewport()){
        goblin.click(new InteractingWithNpcWaiter());    
    }
}
