Anti-magic shield

This shield is made from anti magic shell properties of a flail snail.

A creature that is attuned to this shield and dawning it has advantage on saving throws against spells, and any creature making a spell attack against the creature has disadvantage on the attack roll. If the creature succeeds on its saving throw against a spell or a spell attack misses it, then the creature can use it's reaction and cause an additional effect by rolling a d8 as below.

1–2. If the spell affects an area or has multiple targets, it fails and has no effect. If the spell targets only the target, it has no effect on the target and is reflected back at the caster, using the spell slot level, spell save DC, attack bonus, and spellcasting ability of the caster.

3–4. No additional effect.

5–6. The shield converts some of the spell’s energy into a burst of destructive force. Each creature within 30 feet of the creature must make a DC 15 Constitution saving throw, taking 1d6 force damage per level of the spell on a failed save, or half as much damage on a successful one.

7-8. The shield absorbs the spell and green veins can be seen pulsing all over the shield and body of the creature. The creature gains 1d10 temporary hit points per level of the spell (no effect from cantrips).

Notes: creature proficient with shields.
