Double Cast

Double Cast gives the caster a Doublecasting buff which lasts 90 seconds (this buff is shown on the side of the screen as "Magic×Magic"). While active, all bolt spells have a chance of being cast instantly a second time immediately after the first bolt lands (skill level determines the chance). This skill affects Fire Bolt, Cold Bolt and Lightning Bolt, but not Earth Spike. Bolts which are cast via Auto Spell, scrolls and autocast items are also affected.

On iRO, this skill is known as Double Bolt.
