Crystal Mask is a Seren spell available in the Ancient Magicks spellbook that requires level 90 Magic. Casting it grants the player a 5 minute buff that adds 15% to their pickpocketing success rate and a chance to not be stunned by NPCs upon being caught for a pickpocketing attempt. As part of the Seren spells, Crystal Mask is unlocked after completion of The Light Within quest.

When used in conjunction with the Light Form prayer, the chance of the spell's effects are doubled. For other boosts to Thieving, see Thieving training.

The spell can be recast at any point to refresh the duration with a 10-second cooldown between casts. Casting the spell while pickpocketing will not interrupt it.
