Sandblast is a level 1 Earth Magic spell which fires shrapnel with a range of 4, though it takes 1.5 turns to fire. Sandblast maxes out at 2d20 damage, which is impressive for a level 1 spell. However, damage reduction from enemy AC is applied thrice instead of once, and the slow firing means that enemies will often get more attacks in.

Earth Elementalists begin with this spell memorized.

Strategy

Sandblast is noticeably more MP-efficent than Stone Arrow, dealing the same and even more damage against low-AC foes, but at a 50% slower speed. But as you gain maximum MP, Stone Arrow's damage/turn becomes more noticable than Sandblast's damage/MP.

History

• Prior to 0.29, Sandblast was a range-3 spell that took only 1 turn to fire, but required stones to use.
• Prior to 0.20, Sandblast could be used without stones, with reduced damage. To use the stronger version, the stone had to be wielded. Ogres and trolls could also use large rocks, for even bigger damage.
• Prior to 0.9, AC was only applied twice instead of thrice, making the spell a little more viable against armoured targets.
• Prior to 0.8, Sandblast had a range of 1, but using stones changed it to range 2. Using large rocks did not increase damage.
