Archon Shards:
1x Blue +150 HP
1x Blue Tau-Forged +75 max energy
1x Red +10% power ability
1x Red Tau-Forged +15% power ability
1x Yellow +30% of the maximum energy is filled at the beginning of the mission

Tactics:
You start by activating the first and second ability, then activates the third and fourth ability.
Once this is done, you just have to remember to refresh the third and fourth ability without ever getting them down.
When you have everything active and refreshed, you just have to shoot with your favorite weapon, putting as many effects as possible.
For example, I use [Torid] Incarnon with gas and magnetic, which added to Nourish (viral) and Xata's Whisper (VOID) make 4 devastating simultaneous effects!
