Emperor Edition is the free September 2014 overhaul that rebuilt ROME II's politics, building chains and campaign AI after a rough 2013 launch. It ships the Grand Campaign across 57 provinces stretching from Britannia and Hispania to Bactria, plus the Imperator Augustus campaign covering the Second Triumvirate's civil war. Turn-based empire management feeds into real-time battles of thousands of men, and these are the rules everyone still plays under.
Combat in Total War: ROME II - Emperor Edition rewards knowledge over reflexes. Understanding how each mechanic works (and how they interact) is what turns a struggling player into a dominant one. New here? Start with our beginner's guide for the basics.
Core Combat Mechanics
1. Province and region system
The Grand Campaign splits into 57 provinces, each built from two to four regions with a single provincial capital. Edicts apply province-wide but only once you own every region in it, so a half-conquered province gives you the unrest of occupation with none of the management tools.
Why it matters: This is the foundation of all combat. Everything else builds on this.
2. Public order and food
Food surplus feeds growth while a shortage causes attrition and unrest across an entire province. Public order slides from garrison strength, corruption, foreign culture and squalor, and a province in the red spawns rebel armies behind your front line.
Why it matters: The most underrated mechanic. Players who master this early have a massive advantage.
3. Army traditions and generals
Armies are permanent objects tied to a general and accumulate traditions over campaigns, granting real bonuses such as faster movement or better ambush odds. Disbanding an army throws that history away, which makes retiring a veteran stack a genuine loss.
Why it matters: Unlocks a new layer of gameplay depth once understood.
4. Political parties and civil war
Your faction is divided between rival houses, and Emperor Edition rewrote how their influence moves. Letting your own party's influence collapse or spike triggers a civil war that hands a large slice of your empire to the secessionists.
Why it matters: The tactical edge that separates average players from advanced ones.
5. Combined land and naval battles
Coastal battles put fleets and land armies on the same map, with marines landing straight into the fight. Naval units also carry troops, so a fleet defeat can annihilate an army that never reached shore.
Why it matters: The endgame optimization mechanic. Small improvements here compound into massive gains.
How These Mechanics Combine
Understanding how mechanics interact is where real optimization happens:
Province and region system + Public order and food
The Grand Campaign splits into 57 provinces, each built from two to four regions with a single provincial capital. When combined with Public order and food, food surplus feeds growth while a shortage causes attrition and unrest across an entire province. This combination is the core of every effective build.
Army traditions and generals + Political parties and civil war
Armies are permanent objects tied to a general and accumulate traditions over campaigns, granting real bonuses such as faster movement or better ambush odds. Paired with Political parties and civil war, your faction is divided between rival houses, and emperor edition rewrote how their influence moves. This is why the tier list favors builds that leverage both.
Combined land and naval battles as a Multiplier
Coastal battles put fleets and land armies on the same map, with marines landing straight into the fight. Naval units also carry troops, so a fleet defeat can annihilate an army that never reached shore. This system amplifies everything else. The better your Combined land and naval battles optimization, the more your other mechanics pay off.

Advanced Combat Techniques
Damage Optimization
- Match your equipment to your build's stat priorities
- Exploit Province and region system for maximum damage windows
- Chain Public order and food and Army traditions and generals for combo damage
- Use Political parties and civil war to create openings
Survivability
- Learn enemy patterns before committing to attacks
- Province edicts only unlock once you own every region in a province, so half-conquered provinces cost you unrest without giving you the tools to fix it. Finish one province before opening the next front.
- Position using Province and region system to control spacing
- Save defensive options for guaranteed survival, not comfort
Boss Combat
Bosses test your understanding of every mechanic. See our boss guide for fight-specific strategies.
- Phase awareness: Most bosses change behavior at health thresholds
- Patience over aggression: One extra hit per opening beats dying to greed
- Build preparation: Swap gear and equipment for specific fights when needed
Common Combat Mistakes
- Button mashing: Committed attacks have recovery frames. Mashing locks you into animations.
- Ignoring Public order and food: This mechanic exists for a reason. Players who use it take significantly less damage.
- Wrong equipment for the situation: Check our weapons guide for situational picks.
- Not learning from deaths: Every death teaches something. If you don't know why you died, you'll die the same way again.
- Overcommitting: Trading hits works in Italia but will get you killed in Britannia.
