Alexander - The Soul of the Creator
Alexander - The Soul of the Creator or A12
Strategy
Alexander Prime has a considerable arsenal consisting of several different attacks.
Sacrament: This attack can be recognized by it's large white-blue preparation. Avoiding this can be tricky at first, so if you're not sure where to go, keep watch for where your party went. This can be especially difficult to avoid later in the fight when combined with another AoE being active. Make sure you don't lose track of the boss while under the effects of Temporal Stasis, as he may teleport out of your sight and begin using Sacrament while you cannot see him. This can lead to you, or others in your party being distracted with dodging Gravitational Anomaly.
