Archon Shards :

• 3 Crimson (Preferably Tauforged) Archon Shards :: (+15%) Ability Duration

• 2 Amber Tauforged Archon Shards :: (+37.5%) Casting Speed

• Situational: Replace 1 Crimson Archon Shard for 1 Tauforged Amber Archon Shard :: (+45%) Maximum Energy filled on spawn

Extra Information :

• The nerf to Roar's damage boost, when being subsumed to Protea, is mostly negated by her Passive:

  Every 4th Power Cast is granted +100% Ability Strength.

• Primed Sure Footed is a preference (I use Kuva Ogris a lot), it can be replaced by Cunning Drift / Power Drift / Preparation etc...

• Protea's survivability comes from Grenade Fan's shield satellites and shield gating; Rolling Guard to prevent being killed from toxin. Archon Vitality could remain Rank 0, since it's mainly used for stacking Heat status.

• Primed Flow is a very good QoL, but it can be replaced for more range (Stretch) / more duration (Augur Message) or maybe more survivability (Adaptation)

• In terms of energy management, the 45% efficiency isn't too detrimental, due to the Dispensary and Equilibrium pairing, and especially if your Companion has Synth Deconstruct:

  Enemies injured by the Companions have 25% chance to drop a Health Orb when killed.

Arcane Energize is unnecessary, but Zenurik Focus School can be used if it's still too difficult to manage Energy / for start of mission.

• If you don't have Growing Power, it can easily be replaced for Corrosive Projection, or Brief Respite
