Helm of the Sentinel

This helm has 3 charges for the following properties. It regains all expended charges daily at dawn.

Counterspell. You can use an action to expend 1 charge and establish a defensive ward with a contingent counterspell spell. The next time you can see an unfriendly creature within 60 feet of you casting any spell that either targets you or causes you to make a saving throw, the counterspell spell immediately takes effect whether or not you want it to, as if you had cast it using your reaction. Wisdom is your spellcasting ability for this spell. The ward ends immediately after counterspell takes effect or at dawn.

Protection. You can use an action to expend 1 charge and cast the protection from energy spell on yourself.

Deflection Field. You can use a bonus action to expend 1 charge and cast the shield of faith spell on yourself.
