Elysian spirit shield

The elysian spirit shield was released on 16 October 2014. It requires 75 Defence and 75 Prayer to wield. The shield is made by attaching an elysian sigil, a rare drop from the Corporeal Beast, to a blessed spirit shield. This process requires 90 Prayer and 85 Smithing. Players without the required skill levels to create the shield may ask Abbot Langley in the Edgeville Monastery to combine the sigil and the blessed spirit shield, for a fee of 1,500,000 coins.

Special Bonus
The elysian spirit shield has a 70% chance of reducing the damage you receive by 25%. Without consideration of its magical effect, the shield is nearly as powerful as the Dragonfire shield in defensive bonuses. On the other hand, it lacks the +7 Strength bonus the Dragonfire shield grants.

The elysian spirit shield's special bonus makes this shield one of the strongest shields in RuneScape. On average, players wielding this shield will take 17.5 percent less damage (25*0.70=17.5%). In theory, taking (on average) 82.5% of the damage would mean that a player with a hitpoints level of 99 would really have to be hit with 120 unreduced damage to be killed.

Trivia

 * In classical Greek mythology, there is a realm in the Underworld called the Elysium Fields, or the Elysian Plains. This is the final resting place for the souls of the heroic and the virtuous. However, this was only present in the Tartarus domain of the underworld.
