Each round, everything within a 20-foot radius of the Sand Thing must make a dispel check against the spell with the highest caster level. If that check fails, you make dispel checks against progressively weaker spells until you dispel one spell (which discharges the dispel magic spell so far as that target is concerned for the round) or until you fail all your checks.

Notes:
• Magic items are not affected, but items that have been enchanted are.
• For each object within the area that is the target of one or more spells, you make dispel checks as with creatures.
• For each ongoing area or effect spell whose point of origin is within the area of the dispel magic spell, you can make a dispel check to dispel the spell.
• For each ongoing spell whose area overlaps that of the dispel magic spell, you can make a dispel check to end the effect, but only within the overlapping area.
• If an object or creature that is the effect of an ongoing spell (such as a monster summoned by monster summoning) is in the area, you can make a dispel check to end the spell that conjured that object or creature (returning it whence it came) in addition to attempting to dispel spells targeting the creature or object.
