Azan's Hourglass

The hourglass of Azan, one of his five phylacteries. Whenever a spellcaster attunes to it, they gain the following benefits:

• The hourglass can be used as an arcane focus to cast spells and removes the need to provide any material component, even ones with a cost.
• The hourglass improves your spellcasting. Any time you cast a spell through the hourglass, you can choose to use an action or a bonus action.
• The hourglass holds your life in it's sands. You can use an action to mark your current HP with the hourglass. In thirty seconds, your HP returns to that number. This effect can be used once per dawn and fails to function if you have died in the meantime.
