Earring, Charm Shield:

When a creature successfully casts a charm on you, you will still have a 1 in 6 chance to resist it, even though you failed to resist it.

Example:
A creature casts charm on you.
You fail to resist the charm.
Because you have a Charm Shield on, you roll a D6.
You roll a 1, avoiding the charm.

Note:
Having more than one Charm Shield on does not increase the chance for you to resist being charmed.

Value: 25 Gold.
