All army compositions benefit from good Top-Bar use and Galavax Micro
Use Monoliths for damage output and Area Defense; Remember they fire one extra attack each time a Thrall dies
One Monolith is more useful than any 2 Obelisks
Use Guardian Obelisks for additional damage output
Use Warp Obelisks to quickly traverse the map
Use Healing Obelisks strictly to keep your static defenses alive
Use the Summoning Obelisk to rapidly reinforce the swarm component of your army
Deploy the Empower when pushing into larger bases
Good Galavax Micro involves switching modes, even in the middle of battle
Use Fire Mode's Additional Damage-Over-Time effect to tear down objectives and dangerous opponents
Switch to Fire Form whenever your Lighting Mode abilities are on cooldown
Lighting Mode's stun effect on attack can be useful in smaller fights
Use Lighting Shield to keep units alive or to deal extra damage
Lighting Blast permits rapidly dispatching enemy groups with the upgrade
Mindblaze can provide a good distraction in battles
Fireball can still have some uses for additional damage
Depending on your play-style, difficulty and faction buffs, you may benefit more from delaying upgrading Idal Conduits
I generally start making Idal Conduits after getting my initial army ready, aka 1 Terror Tank/Dreadnought/5 Dark Disciples
Terror Tank (3× Soul Dynamo, 1× Shields) – Thrall (Witness Me) - Dreadnought (Tempest Core)
Durable and effective, but can have body-blocking issues
Easier to establish than other compositions
A single Terror Tank with Soul Dynamo and good micro and carry the mid-game
Soul Dynamo is amazing, more DPS than the main gun if used right
Aim for 2-3 Terror Tanks
Prioritize getting 2 Soul Dynamo over a second Terror Tank
Use subsequent Flux to construct Tempest Dreadnoughts
Aim for 2-4 Dreadnoughts
Remember Steelsworn can be sacrificed to Terror Tanks too
Reliable on every mission and works from level 1
Optional: Forego Shields on subsequent Terror Tanks/module rebuilding and use more Thralls to tank
Caution: AoE effects can rapidly destroy modules
Excellent on: Pirating Power and Critical Delivery
Dark Disciple – Thrall (Witness Me) - Steelsworn
Simple and effective; Attack-move toward the target
Expensive to establish
Vulnerable to AoE, crowd control, and body blocking
Lower mobility
Leaves more room to micro Galavax
Aim for 15–25 Dark Disciples
Excels in sustained combat
Excellent on: Metal March and Industrial Warfare
Dreadnought (2× Full Missiles; remaining 2× Tempest) – Thrall
Simple and effective; attack-move toward the target
Even more expensive to establish
Its power depends on your ability to flood the field with Thralls
Can work just fine with 10 Empowered Conduits pumping Summoning Obelisks
Aim for 4–5 Dreadnoughts
Great against objectives
Benefits from allies with swarm-heavy armies
Can add more or fewer Missile Dreadnoughts depending on Enemy Comp
Reliable on every mission
Excellent on: Metal March
Storm Bringer – Thrall (Witness Me) – Steelsworn – Dark Disciple
Niche composition
Build a core of 10–20 Storm Bringers
Use 10–25 Steelsworn as a replenishable front-line
Optional: Add 5 Dark Disciples for cleanup DPS
Much more micro-intensive
Vulnerable to crowd control and charging units
Not strongly hindered by energy
Less effective against siege mechs, but can still melt Monstrosities
Excellent on: Pirating Power and Critical Delivery
