• Shock Trooper for damage, also to ensure you have Radiation damage if Zenith/Knell/Vermisplicer are modded for Heat damage.
• Eclipse infused for massive damage buff; to get the most out of this be sure to have completed The New War and turn Enhanced graphics engine on, Dynamic Lighting off, HIgh Shader Quality on.
• High strength for Shock Trooper, Speed, and Eclipse.
• Vigorous Swap for damage; fun fact, this can be procced more quickly by double-tapping your Synthesis Scanner bind than actually swapping weapons.
• Three Umbral mods for survivability; more health, armour, and Tau resistance - as well as the 22% strength from set bonus - far outweigh the benefits of Adaptation (which is currently bugged and does not work when reentering plains if the buff is active when extracting).
• [Holster Amp] for more damage on limbs; [Corrosive Projection] is only useful for water limbs, and generally only one is needed (I typically run one Holster Amp and one Corrosive Projection in duos).
• Arcane Velocity for more fire rate on Knell/Vermisplicer.
• Arcane Nullifier to avoid losing energy after limb breaks.

Currently I have one Tauforged Amber Archon Shard for casting speed and four Crimson Archon Shards (one Tauforged) for Ability Strength, so this is really 292% strength; with four Tauforged Crimson shards it would be 307% strength.
