Ideas behind this build:

• [Umbral Vitality] and [Adaptation] for survivability
• [Smite Infusion] to buff radiation damage from sniper (e.g. [Rubico Prime]), causing more damage to Eidolons.
• Strength to make [Smite Infusion] and Renewal more powerful.
• [Streamline], [Primed Continuity] and [Primed Flow] to make it easier to keep Renewal up.
• [Dead Eye] to buff sniper damage and Arcane Momentum to reload snipers faster.
• Arcane Nullifier as backup in case Hallowed Ground isn't up.
