Build around combined Imps and Raptors
Combine your Imp troops with Unify, strengthen the resulting carry with Gigantify, and recruit Raptors for additional mounted power. This combination has worked in earlier Imperium attempts; use it as a build route to adapt to your difficulty.
Match the challenge and difficulty
Imperium is a King of Blood challenge. Quest Mode includes Knight, King, and Chaos difficulties. Before committing to the Imp-carry route, check your selected difficulty and which of its key pieces are available in your attempt.
Combine, strengthen, then recruit Raptors
- Use Unify to combine your Imp troops into the carry you intend to strengthen.
- Apply Gigantify to the combined Imp carry to buff it.
- Recruit Raptors to add mounted power to the Imp-focused army.
Use Migration when the carry needs repositioning
Another Imp-focused approach prioritizes a level-3 Imp group and concentrates available units with Migration and further Unify plays. Migration moves its target to an empty adjacent plot and grants +10% damage and HP. Keep a suitable destination empty if you intend to reposition your carry with it.
When an Imp-only army stalls
Imp level-ups add +100% damage without adding HP. If an Imp-only army is stalling, prioritize adding Raptors before spending more resources on the same approach. Raptors were a successful addition in attempts where pure Imp and altar-based armies struggled.
Account for changes since older clears
The Imp-and-Raptor advice predates patch 31, which slowed Imperium's enemy progression. It also precedes the PC full release on November 12, 2026. Keep that timing difference in mind when adapting the combination to your selected difficulty.
