Angelis Bell

By understanding how to protect anyone from the damage, you claim at your preferred Deity, to summon a protective force over yourself and your selected party members. By doing this, you select up to 3 targets. Then, while you perform this cast, you must use the bell ( which later it will be consumed by this spell ) to doll it over those selected targets, each doll for each target selected.
After that, a Holy ( and also Illusory ) magical bell, appears above each target, giving them a shield buff on their AC. Needless to say that bell it's an illusory image, so it cannot be targeted nor damaged by any means. The selected targets gets a boost on their AC equal to the caster's spellcasting modifier, which it last 1 hour. If those targets gets hitted, the illusory bell it dolls so soundly,  forcing the attacker to roll a WIS DC 15 saving throw. If it succeeds, the attacker dosen't takes damage nore any other bad condition effects. If it fails the roll, the targets automaticly gets deafened 1 turn.
