Rising Mace

The Rising Mace is a Mace-class Artifact weapon found in. Visually, the Rising Mace resembles a light blue mace.

In
The Rising Mace is acquired as a rare drop from a Blue Dragon at Jupiter Lighthouse. The Rising Mace, as a Mace-class item, can be wielded by Isaac, Garet, Mia, Felix, Sheba, and Piers.

The Rising Mace's Unleash effect is High Vitals, which activates at a rate of 35% (which is standard) and converts the attack into a Jupiter-elemental attack with 52 extra attack points added, and the effect may add damage done to the user's HP. High Vitals merely visually resembles the wielder attacking and blue balls of energy being siphoned from the enemy into the wielder.

The Rising Mace is acquired in Jupiter Lighthouse, but only later on in the lighthouse's right tower accessible with the Hover Psynergy, because that is where Blue Dragons reside. If found at this time, the Rising Mace makes for an excellent weapon for Sheba because of the matching Jupiter influence and the need for her to restore her lower HP.
