Ubisoft Quebec released Assassin's Creed Odyssey on 5 October 2018, dropping the series into 431 BCE and the Peloponnesian War. You choose Alexios or Kassandra, a Spartan mercenary carrying the broken spear of Leonidas, and later patches pushed the level cap to 99. Forty two members of the Cult of Kosmos have to be unmasked before the Ghost of Kosmos will meet you face to face.
Combat in Assassin's Creed Odyssey 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. Three ability trees
Forty four skills sit across the Hunter, Warrior and Assassin trees, and you can slot them freely rather than being locked into one. Skill points come from levelling, from ancient steles scattered around Greece, and from objectives in the Fate of Atlantis expansion.
Why it matters: This is the foundation of all combat. Everything else builds on this.
2. Adrenaline fuelled abilities
Abilities burn adrenaline segments that fill as you fight, so damage output is a resource you generate rather than a cooldown you wait out. Overpower attacks spend the whole bar at once for a scripted heavy hit.
Why it matters: The most underrated mechanic. Players who master this early have a massive advantage.
3. Engravings on gear
Engravings are permanent stat perks applied at a blacksmith, unlocked by dismantling legendary equipment, solving Ainigmata Ostraka tablets and clearing mercenary tiers. They are how a low level favourite weapon stays useful at level 99.
Why it matters: Unlocks a new layer of gameplay depth once understood.
4. Mercenary tiers and bounties
Nine tiers of rival mercenaries hunt you when your bounty rises, and you climb from tier 9 toward tier 1 by killing them. Completing a tier by defeating at least five mercenaries grants permanent perks.
Why it matters: The tactical edge that separates average players from advanced ones.
5. Conquest battles and naval warfare
Every region has a Nation Power gauge that you drain by burning war supplies, looting treasury and killing the leader, which opens a Conquest Battle. At sea the Adrestia fights with arrows, javelins and ramming, and hull upgrades add lieutenant slots up to a maximum of four.
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:
Three ability trees + Adrenaline fuelled abilities
Forty four skills sit across the Hunter, Warrior and Assassin trees, and you can slot them freely rather than being locked into one. When combined with Adrenaline fuelled abilities, abilities burn adrenaline segments that fill as you fight, so damage output is a resource you generate rather than a cooldown you wait out. This combination is the core of every effective build.
Engravings on gear + Mercenary tiers and bounties
Engravings are permanent stat perks applied at a blacksmith, unlocked by dismantling legendary equipment, solving Ainigmata Ostraka tablets and clearing mercenary tiers. Paired with Mercenary tiers and bounties, nine tiers of rival mercenaries hunt you when your bounty rises, and you climb from tier 9 toward tier 1 by killing them. This is why the tier list favors builds that leverage both.
Conquest battles and naval warfare as a Multiplier
Every region has a Nation Power gauge that you drain by burning war supplies, looting treasury and killing the leader, which opens a Conquest Battle. At sea the Adrestia fights with arrows, javelins and ramming, and hull upgrades add lieutenant slots up to a maximum of four. This system amplifies everything else. The better your Conquest battles and naval warfare optimization, the more your other mechanics pay off.

Advanced Combat Techniques
Damage Optimization
- Match your equipment to your build's stat priorities
- Exploit Three ability trees for maximum damage windows
- Chain Adrenaline fuelled abilities and Engravings on gear for combo damage
- Use Mercenary tiers and bounties to create openings
Survivability
- Learn enemy patterns before committing to attacks
- Dismantle legendary gear you will never wear instead of selling it. Dismantling is a main source of engravings, and an engraving unlocked once can be applied to any future weapon at a blacksmith.
- Position using Three ability trees 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 Adrenaline fuelled abilities: 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 Kephallonia but will get you killed in Lakonia.
