Lucky arcane spirit shield is a very rare reward from the Squeal of Fortune daily event. It has the same stats and level requirement as a normal Arcane spirit shield but it can't be traded or sold. This item will not appear under a gravestone if a player dies but can be protected as an item kept on death. As such, it is recommended to avoid taking this item into any situation where it cannot be chosen as an item kept on death. Additionally, you do not have to complete Summer's End quest to be able to wear it.
