You speak a word of unmaking that devours all wood and leather in the area, destroying leather armor, shield straps, spear shafts, arrows, bows, staves, clubs, and so forth, including your own items. Objects made of other materials, such as linen, wool, glass, and metals, are unaffected. Items that are worn or held gain a collective Dexterity saving throw by the wearer. On a successful save, none of that wearer’s items are affected. Magical items are never affected by this spell.
