In order to cast spells in E:ID, you must first have found a catalyst called “Toastmaster’s Tome” which can be found randomly spawning in chests.
Once you have obtained a tome, you must equip it into a weapon slot and ready your weapon.
To cast a spell you must input runes using your arrow keys, Up, Down, Left, Right. Inputing the wrong combo or a random combo will cast a random spell.
There are currently 4 spells in the game which are;
Fire Bolt: Right, Right, Right
Fires a projectile which locks onto a target and deals fire damage
Fire Breath: Right, Right, Right, Up
Like fire bolt, but ignites the area around the explosion point, causing creatures to burn.
Frost Bolt: Right, Left, Left
Fired a projectile which locks onto a target and deals frost damage
Lightning Bolt: Right, Down, Down
Fires a beam which deals lightning damage
While casting spells is fun, and very powerful, be careful not to meet your untimely death by your own hand. Make sure you have enough distance between yourself and your target when casting.
Casting spells builds up corruption, which is indicated by a purple bar between your health and stamina, if this bar fills completely, you will explode.
Beneath the purple bar is a smaller white bar which indicates your focus. As you cast spells your focus will deplete. Focus determines the rate at which your corruption lessens.
