Early (no Archon Vitality) Protea Prime build.

Empty slot choices:

• The new augment.
• Augur Reach for more range and extra shield restore.
• Archon Vitality if you have it.
• Intensify for strength, or Augur Secrets for strength and extra shield restore.
• Maybe Streamline, but I suspect Flow + Equilibrium + Dispensary is enough.

The new augment is interesting; to give you a long-lasting [Blaze] Artillery you still need to build duration for Temporal Anchor, so it doesn't change the build in that sense. Maybe mostly useful for mobility?

Other future upgrades:

• Growing Power aura.
• Add an Exilus: Power Drift, Cunning Drift, Radar, PSF, etc.
• [Primed Flow].
