Water Blast is a water-based blast spell in the standard spellbook, requiring level 47 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 water spell available to free-to-play players.

Damage

Water Blast's base maximum hit starts at 14 and increases as the player unlocks additional blast spells, up to 16 at level 59 Magic.

Magic level	Highest-level blast spell available	Water Blast base maximum hit
47 - 52	Water Blast	14
53 - 58	Earth Blast	15
59 +	Fire Blast	16

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

As a water-based spell, Water Blast's maximum hit is also increased against targets that are weak to water.
