Earth Blast is an earth-based blast spell in the standard spellbook, requiring level 53 Magic to cast. As an offensive combat spell it can only be cast on attackable NPCs, or other players in a PvP situation.

It is the strongest earth spell available to free-to-play players.

Damage

Earth Blast's base maximum hit starts at 15 and increases to 16 when the player unlocks Fire Blast at level 59 Magic.

Magic level	Highest-level blast spell available	Earth Blast base maximum hit
53 - 58	Earth Blast	15
59 +	Fire Blast	16

As with all combat spells, Earth Blast's maximum hit is also increased based on the player's magic damage bonus.

As an earth-based spell, Earth Blast's maximum hit is also increased against targets that are weak to earth.
