Vantric

Vantric, the Razorbane, is a legendary shield created by Tireas, and part of the Arms of Tireas.
==History==
The artifact was created when Tireas battled the water god Tsiyoti, who managed to shatter Tireas' shield. A particularly large chunk fell all the way near Hearth, fortress of the Embrin. Vantric is currently in their possession.

Spikes of the Warbringer: Vantric deals 1d8+5+(user's strength modifier) damage when it is used to attack. It's +5 enhancement also applies to its accuracy rolls.﻿
Razorbane: Anyone who misses the wielder of Vantric is subject to an immediate sunder attempt, using the statistics of the shield for the attempt. Only the weapon used for the attack may be sundered, and ranged weapons are unnaffected.
Warding: Vantric's armor bonuses apply to touch AC.
Retribution: Anyone who damages the wielder of Vantric must make a will DC equal to 20 + the wielder's charisma modifier. If the save is failed, the attacker takes damage equal to what they delt.
Negation: Any Arm of Tireas within 100 feet of the wielder of Vantic has all of its unique abilities (besides attunement) negated. If Negation is in effect, Vantric loses its unique abilities as well. If the wielder of Vantric possesses another Arm of Tireas, this effect does not occur.﻿
Attunement: Like all other Arms of Tireas, the wielder of Vantric knows the location of all other Arms of Tireas, regardless of distance or planar separation.
