They attack in the form of a Melee Spear attack, regardless of which weapon and specialization the Amazon has. Valkyries have much more endurance than Hirelings, and can be continuously summoned as long as there is sufficient mana. Even if somehow the enemy inflicts significant damage upon her, she may be healed to full by simply resummoning her. With fully synergized Decoy and Penetrate (plus 10 points into the other four synergies) this summon gains around 11,000 Life, ~50% chance to avoid all attacks, and ~60% chance to deal twice the amount of damage. This summon becomes very strong and durable with more points invested. Valkyrie receives bonuses from nearly every ability on the Passive and Magic Skills tree. Valkyries are powerful summoned tanks, which are especially useful for Amazons that wish to stay at range. It is believed this gift is a sign that your place beside the Goddess is assured when you pass from this world-perhaps even as a Valkyrie.

The power to summon a Valkyrie is the greatest honor that an Amazon warrior can receive.

These emissaries of Athulua are called Valkyrie, and they are the spirits of the greatest heroes from the Amazon people.

When a warrior has proven her devotion to Athulua through her brave deeds and exceptional skill in battle, the Goddess shows her favor by granting a spiritual emissary to aid the Amazon.
