Ancients Awakened/Sagittarius Shield

Sagittarius Shield is an equipable accessory that is dropped by a ' in Expert Mode. Pressing the accessory ability hotkey will put a protective barrier around you to protect you from incoming damage. During this state, your life regen is boosted drastically but you can't use any items, and this state lasts for 5 seconds. This ability has a 5 minute cooldown before it can be used again.

Trivia

 * The function of accessory is based on something Sagittarius used to execute when its second phase was present: Shielding itself and heal. However, that ability of the boss was removed.
