Breach Surge can be any helminth you like...Breach Surge is just my favorite. Nourish would be my second choice as it has a brief stun, would aid in shield gating, and vastly improves energy economy.

Run with Unairu to replace the missing Prime [Sure Footed], since I don't have it yet, and strip Demo armor...let your 2 melt them...no primer needed.

This build relies on having at least 2 Augur mods on your secondary weapon to fully shield gate on every cast of Breach Surge. Furthermore, it requires AT LEAST 25% (must [Reach] 164% total) strength from Archon Shards.

Archon Shards:
1 Crimson Strength Archon Shard
1 Tauforged Crimson Strength Archon Shard
2 Crimson Duration Archon Shard
1Tauforged Amber Energy Orb Effectiveness Archon Shards

Arcanes:
Arcane Energize is MANDATORY, but only requires rank 3 to be effective.
Molt Efficiency is a flex slot and can be whatever you want!

Enjoy!
