Keep in mind that VojToyas is not working with Invoker 6pc bonus and skills that use thorns dmg. That shield only buffs your actual thorns damage that is dealt by being attacked and the damage from the axe Hack. I would strongly discourage anyone from using this shield.
Don't use VojToyas. A better combination (for 2 shields) would be cube/equip combo of Akarat's Awakening and the Coven's Criterion. Get cooldown reduction and damage mitigation. However, it would be better to equip AA or CC and cube a Blood Brother if you have it.
