An ethereal shield with an elysian sigil attached to it.
The Elysian spirit shield is one of the six spirit shields and the second most expensive, behind the Divine spirit shield. It can be obtained by getting an Elysian sigil drop from the Corporeal Beast and then adding the sigil to a Blessed spirit shield, which is a normal Spirit Shield enhanced with a Holy elixir which can also be obtained as drops from the Corporeal Beast. Other methods of obtaining this item include buying it from the Grand Exchange or by trading with another player. The reason for the high value of the shield is due to the hidden bonuses it provides.
When worn, the Elysian Spirit Shield has a 70% chance of reducing damage on you by 25%, at the cost of no prayer points. For this reason it is extremely sought after. Its rival, the Divine spirit shield, has the ability to reduce damage by 30% at the cost of some prayer points 100% of the time. For this reason it is often used instead of the Elysian.
