You speak the words of this spell, and tendrils of purple darkness rise from the ground, surrounding you and concealing you from your foes.

Swirling wisps of darkness obscure your form, granting you concealment. The 20% miss chance is in effect even if the attacker has darkvision.

This spell effect is dispelled in daylight or in the area of a light spell of 3rd level or higher.

See invisibility does not counter a veil of shadow's concealment effect, but a true seeing spell does.
