Valve stopped developing Dota Underlords. The last patch arrived on 8 December 2021 and its headline note extended the Season 1 end date to 2031, which in practice means no further content or balance work. Servers stay online and matchmaking still fills, with SteamDB tracking roughly 1,000 to 1,300 concurrent players in August 2026 against an all-time peak of 202,334 on 23 June 2019, so what you are playing is a frozen 2021 auto-battler rather than a supported competitive game.
Combat in Dota Underlords 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. 8x8 board placement
You arrange purchased heroes on an 8x8 grid during a preparation phase, then the round resolves automatically with no further input. Where a unit stands decides who it walks into first, which matters more than most new players expect.
Why it matters: This is the foundation of all combat. Everything else builds on this.
2. three-copy hero upgrades
Three copies of the same hero merge into a two-star version, and three two-stars merge again into a three-star. Chasing a three-star costs nine copies of a unit that other players are also buying from a shared pool.
Why it matters: The most underrated mechanic. Players who master this early have a massive advantage.
3. alliance bonuses
Fielding several heroes from the same alliance grants a shared bonus that scales in steps, so three Warriors give the whole team armor. The Warrior alliance is widely rated the strongest defensive package in the game precisely because a three-stack is cheap.
Why it matters: Unlocks a new layer of gameplay depth once understood.
4. gold interest and streaks
You bank interest of one gold per ten held, capped at five per round, and win or loss streaks pay their own bonus on top. Deciding whether to spend on rerolls or hold for interest is the entire economic layer.
Why it matters: The tactical edge that separates average players from advanced ones.
5. Underlord pick at round 10
At round 10 you choose one of four Underlords, Anessix, Hobgen, Jull or Enno, and each is offered in one of two randomly selected builds. The Underlord fights on your board for the rest of the match, so the pick changes both your damage profile and your alliance count.
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:
8x8 board placement + three-copy hero upgrades
You arrange purchased heroes on an 8x8 grid during a preparation phase, then the round resolves automatically with no further input. When combined with three-copy hero upgrades, three copies of the same hero merge into a two-star version, and three two-stars merge again into a three-star. This combination is the core of every effective build.
alliance bonuses + gold interest and streaks
Fielding several heroes from the same alliance grants a shared bonus that scales in steps, so three Warriors give the whole team armor. Paired with gold interest and streaks, you bank interest of one gold per ten held, capped at five per round, and win or loss streaks pay their own bonus on top. This is why the tier list favors builds that leverage both.
Underlord pick at round 10 as a Multiplier
At round 10 you choose one of four Underlords, Anessix, Hobgen, Jull or Enno, and each is offered in one of two randomly selected builds. The Underlord fights on your board for the rest of the match, so the pick changes both your damage profile and your alliance count. This system amplifies everything else. The better your Underlord pick at round 10 optimization, the more your other mechanics pay off.
Combat by Build
Each build approaches combat differently:
Warrior Frontline (A-Tier)
Combat approach: Balanced combat style. Key equipment: Aegis of the Immortal Primary mechanic: 8x8 board placement
Warrior Frontline offers a solid combat experience. Full setup in our builds guide.
Assassin Burst (A-Tier)
Combat approach: Spread your own units into corners so enemy Assassins land badly, then let yours dive. If your opening jump fails twice in a row, pivot rather than reroll deeper into the same board. Key equipment: Vladmir's Offering Primary mechanic: three-copy hero upgrades
Assassins jump the enemy back line at the start of combat and try to delete the carry before it acts. Full setup in our builds guide.
Mage Magic Damage (A-Tier)
Combat approach: Balanced combat style. Key equipment: Blade Mail Primary mechanic: alliance bonuses
Mage Magic Damage offers a solid combat experience. Full setup in our builds guide.
Knight Defense (A-Tier)
Combat approach: Balanced combat style. Key equipment: Refresher Orb Primary mechanic: gold interest and streaks
Knight Defense offers a solid combat experience. Full setup in our builds guide.
Hunter Scaling (B-Tier)
Combat approach: Sit Hunters on the back two rows behind a real frontline and never let them be the closest target. Add Vladmir's Offering as soon as it appears in an item pick. Key equipment: Vitality Booster Primary mechanic: Underlord pick at round 10
Hunters convert a long round into steady ranged damage, so the comp beats anything that fails to kill quickly. Full setup in our builds guide.
Advanced Combat Techniques
Damage Optimization
- Match your equipment to your build's stat priorities
- Exploit 8x8 board placement for maximum damage windows
- Chain three-copy hero upgrades and alliance bonuses for combo damage
- Use gold interest and streaks to create openings
Survivability
- Learn enemy patterns before committing to attacks
- Know what you are signing up for before you install. The 8 December 2021 patch pushed Season 1 to 2031 and no balance changes have followed, so every comp you read about in a 2020 guide is still exactly as strong or weak as it was then. That stability is genuinely useful for learning, but there is no meta to keep up with.
- Position using 8x8 board placement 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 three-copy hero upgrades: 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 Standard but will get you killed in Ranked matchmaking.
