Crown of Corruption

Wondrous item, very rare (requires attunement)

This crown appears to be made of sharp obsidian and is adorned with precious gems that range from blue to purple. Even just laying eyes on it compels people to wear it or seek the power that it represents. It has passed hands from one kingdom to the next, coveted as a spoil of war for ages untold. When worn, the crown increases your Charisma to 20 if it is not already 20 or higher. It also allows you to expend a charge to cast either the domination or suggestion spell. The crown has two charges that recharge at midnight.

Curse. Once per week, the crown takes a wicked idea from your head and makes it real, as per a wish. The crown will make anything manifest, short of ending your life, though you are free to fulfill that wish yourself.
