Mechanicus II Dominion explained
DominionDominion is the Necron momentum layer. Create early damage, convert it into better turns, and avoid passive openings where the enemy controls the board first.
Mechanicus II Canoptek Wraith
WraithUse Wraith-style mobility as leader protection and emergency angle correction. It is strongest when it prevents a reset, not when it chases isolated damage.
Necron Campaign Strategy
A good Necron guide has to serve two different players. New players need to know why the faction feels punishing when they hesitate. Older tactics players need to know when the aggressive answer becomes overextension. This page treats launch-window information as a practical framework rather than a final mission-by-mission script. If a later patch changes ability values or exact unit behavior, the decision rules still hold: protect the mission anchor, create damage lanes, convert Dominion, and do not leave the whole board dependent on one resurrecting unit.
| Step | Do this | Why it matters |
|---|---|---|
| Dominion economy | Treat Dominion as battle momentum, not a passive meter. Build it by creating damage turns early, then convert that advantage before the enemy stabilizes. | Launch-window guides agree that Necrons reward forward pressure. Exact rank breakpoints should still be checked against your current patch. |
| Reanimation Protocols | Use reanimation as tempo insurance, not permission to feed units. A downed unit may return later, but the board can collapse while it is missing. | The practical lesson is timing: you still need safe positions, target priority, and bodyguard spacing while the unit is unavailable. |
| Canoptek Wraith bodyguard | Keep Wraith-style mobility near Vargard Nefershah or whichever leader your mission cannot afford to lose. Use mobile units to rescue positions, screen angles, and stop surrounds. | Leader exposure is the failure point that turns a winning damage race into a reset. |
| Terrain pressure | Break or bypass enemy cover when it creates cleaner shots next turn. Do not destroy scenery just because a unit can do it. | The useful chain is cover pressure to enemy movement to cleaner damage to faster Dominion. |
| Mission strategy | Open by identifying your leader lane, two repeatable damage lanes, and one fallback position. Push after those are set, not before. | This keeps the aggressive identity without pretending every map is solved by charging forward. |

First Three Turn Plan
On turn one, do not ask "how much damage can I do?" Ask which lane keeps the leader alive and which enemy position can be pressured without losing the fallback route. On turn two, convert the safest damage lane into Dominion pressure or enemy displacement. On turn three, decide whether the fight is now a push, a reset, or an objective race. This three-turn check gives new players a repeatable opening and gives veteran players a fast way to identify whether the map rewards aggression or patience.
Dominion vs Cognition
| Aspect | Necrons (Dominion) | Mechanicus (Cognition) |
|---|---|---|
| How you get it | Create useful damage turns and keep tempo active. | Use unit actions, positioning, and resource habits to support Cognition flow. |
| Persistence | Treat it as mission tempo; verify exact behavior in the current patch. | Treat it as mission tempo; verify exact behavior in the current patch. |
| Playstyle | Controlled aggression: pressure, lane creation, and leader protection. | Positional control: cover, timing, support, and specialist protection. |
| Defense | Reanimation and bodyguard spacing buy time after bad trades. | Cover and support timing reduce the chance of bad trades. |
| Beginner friendly? | Good for players who learn by pushing tempo and accepting risk. | Good for players who learn by slowing down and stabilizing positions. |
| Leader risk | Keep Nefershah near safe mid-line support, not isolated front pressure. | Keep Faustinius protected until a mission proves exposure is safe. |

Bodyguard and Reanimation Rules
For new players
- Before ending a turn, ask which enemy can reach your leader.
- Keep one mobile rescue option within useful range of that lane.
- Do not count a reanimating unit as active board control.
- Use basic bodies to block clean paths, not only to deal damage.
For experienced players
- Trade a body only when the next activation still leaves a safe lane.
- Use mobility to change enemy targeting, not just to escape after a mistake.
- Break cover to force movement before committing your main damage.
- Track which unit is allowed to fail and which unit must survive.
Necron Failure Diagnosis
If a Necron mission feels unfair, do not immediately blame the unit list. Most failed runs come from one of four mistakes: the leader is too far forward, Dominion is not being created early enough, a downed unit leaves the board empty, or terrain was destroyed without a follow-up lane. Diagnose the failure before changing the whole roster.
| Symptom | Likely cause | Fix next attempt |
|---|---|---|
| Leader dies while enemies are low | Damage plan worked, protection plan failed. | Move the leader lane back one step and keep mobility nearby. |
| Dominion never snowballs | Opening turns are too passive or targets stay protected. | Create two safe damage lanes before ending turn one. |
| Reanimation does not save the fight | The downed unit was holding the only useful lane. | Keep a second body ready before trading the first one. |
| Cover breaks but nothing improves | Terrain destruction was cosmetic, not tactical. | Break only the cover that opens a shot, flank, or objective route. |

Frequently Asked Questions
Q: How do Necrons work in Mechanicus II?
Necrons use Dominion instead of Cognition, so their strongest turns come from damage pressure, board tempo, and keeping leaders safe while the faction snowballs. Reanimation gives room for risk, but it does not erase positioning mistakes.
Q: What are Reanimation Protocols?
Reanimation Protocols let Necron units return after being downed, depending on unit type and mission state. Treat this as tempo insurance, not immortality. If a downed body leaves your leader exposed or your damage lane empty, the fight can still fall apart.
Q: Should I play Necrons or Mechanicus first?
Pick Mechanicus first if you learn tactics games through cover, support, and safer positions. Pick Necrons first if you learn faster through pressure, trading, and aggressive tempo. The claim that one side is always the correct first pick is too broad.
