Anti-magic Amulet

This amulet can absorb up to 5 levels of spells directly targeting the wearer (i.e. one 5th level; one 3rd and two 1st levels; ect.) by spending one charge per level of spell being absorbed.  Alternatively, it can be used to mitigate a spell's effect by spending two charges to reduce the spell's damage or duration by half.

As long as any charges remain, all cantrips targeting the wearer may be absorbed without spending any charges. Additionally, the wearer becomes immediately aware that a spell targeting them has been cast, as well as the spell's level (though not the source or effect).

This effect must be used prior to damage or saving throws being rolled. 

1d6 - 1 (min 1) charges are restored at dawn.

Notes: humanoid.
