Description	Create a mask that will bolster your ability to avoid being spotted by your pickpocket targets and has a chance to protect you from being harmed by them. This effect will last for 5 minutes. Crystal mask will protect the wearer once from Croesus's fungus attacks.

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.

Common use cases

• Croesus - protects the player from taking the first hit of most stat-draining attacks, including spore bombs, sticky fungi, and slime moulds.
