This guide names late-game bosses and describes their phases. It avoids story-ending details where possible, but the final encounter and several DLC identities are spoilers.
Fast answer
The answer before the background
There are four major bosses in the original campaign: Goregrind, Corrupted Denas, Seeress Mydrias and The Overseer. The added campaigns introduce Navira, Abominor and Mygale, while later DLC adds Grymbeard, Princess Iron Fan, Bull Demon King, Murglum, Drakmother and Tyranthor. Bosses are encountered at scripted late-wave or final-stage events rather than random spawns. Build defenses around the boss’s resistance and movement pattern, keep a second damage type ready, and save hero abilities for the transformation or final phase. No verified boss-specific equipment or character-drop system exists; rewards are normally stage completion, achievements, gems and the campaign’s usual progression rewards.
Roster
Every major boss and where to find them
The original campaign’s boss sequence is Goregrind in The Wildbeast Den, Corrupted Denas in Canyon Plateau, Seeress Mydrias across Canyon Plateau and The Eyesore Tower, and The Overseer in Hunger’s Peak. Mydrias and Denas are part of the same story arc, but they are separate boss encounters.
The additional campaigns expand the list. Undying Fury ends with Navira at Temple of the Fallen. Ancient Hunger ends with Abominor at Starving Hollow. Arachnophobia ends with Mygale at The Forgotten Throne. The Colossal D warfare campaign adds Grymbeard encounters, while Wukong’s Journey adds Princess Iron Fan and Bull Demon King. Current reference material also lists Murglum in Dragon Wars, alongside Drakmother and Tyranthor. Some community pages spell Murglum as Murglun; the current developer patch notes use Murglum.
- Original campaign: Goregrind, Corrupted Denas, Seeress Mydrias and The Overseer.
- Additional campaigns: Navira, Abominor and Mygale.
- DLC and later campaigns: Grymbeard, Red Boy, Princess Iron Fan, Bull Demon King, Murglum, Drakmother and Tyranthor.
- Treat minibosses as separate threats. A miniboss can appear during a stage without being the campaign’s named final boss.
| Boss | Campaign or stage | Encounter condition | Best first response |
|---|---|---|---|
| Goregrind | The Wildbeast Den | Wakes during the late waves and enters the map after the stage’s final buildup. | Use strong physical damage, two durable blockers and towers covering his landing routes. |
| Corrupted Denas | Canyon Plateau | Released after the main waves, with support from Seeress Mydrias and Vez’nan. | Use true, armor-piercing or resistance-bypassing damage and remove supporting illusions quickly. |
| Seeress Mydrias | Canyon Plateau and The Eyesore Tower | Appears through scripted story phases and changes position after losing health. | Mix magic and physical damage; block only with tough units and avoid clumping them. |
| The Overseer | Hunger’s Peak | Final campaign encounter with chained, phase-based battlefield effects. | Protect the core defense, reposition when lanes change and save crowd control for dangerous summons. |
| Navira | Temple of the Fallen | Disables towers before entering the route after the late waves. | Spread tower investment, kill nearby Specters and prepare for his unblockable tornado form. |
| Abominor | Starving Hollow | Breaks free after the late-wave sequence and changes form while advancing. | Use disposable blockers early, keep valuable towers spread out and prepare for Crokinder spawns. |
| Mygale | The Forgotten Throne | Descends for the final fight after the campaign’s spider waves. | Prioritize web and drain effects, maintain anti-air coverage and avoid relying on one chokepoint. |
The official pages confirm the campaigns and stage names but do not publish one consolidated boss database. The expanded name list above uses the official campaign material together with a maintained community reference. If a future update adds a boss, verify its stage and mechanics in the in-game encounter information before treating this list as final.
Counters
How to prepare for each boss type
The safest general setup uses one reliable stall point, one high-damage physical tower, one strong magical tower and enough ranged coverage to handle flying or summoned enemies. Two heroes are available in Alliance, so use one durable front-line hero and one ranged or area-damage hero unless the map strongly favors another pairing.
For armored bosses, prioritize magic, true damage and resistance reduction. For magic-resistant bosses, use physical towers and abilities that ignore or reduce resistance. A mixed defense is especially important against Corrupted Denas and Mydrias because their defenses and phases change during the encounter.
- Goregrind: Place damage towers near his starting route and keep melee heroes ready to intercept him. Do not stack every unit under his jump destination.
- Corrupted Denas: Use resistance-bypassing abilities such as Arcane Wizard’s Disintegrate and Ballista Outpost’s Final Nail when available. Use Vez’nan’s control effects during the boss phase.
- Seeress Mydrias: Attack while she is blocked because her high defenses can drop during combat. Do not surround her with weak units, since her area attack punishes crowded blockers.
- The Overseer: Treat the fight as a map-management encounter. Rebuild or reposition immediately when the battlefield changes instead of trying to preserve an outdated chokepoint.
- Navira: Spread towers so a random disable does not remove your entire damage plan. Focus Specters and use strong blockers for his normal form.
- Abominor: Build cheaper or less important towers near likely targets, keep premium towers farther apart and stall the early forms before the final unblockable phase.
- Mygale: Keep ranged damage active when towers are stunned or webbed, and use heroes to finish summoned Leechfangs before they overwhelm the lane.
- Dragon Wars enemies: Stop Draks before they evolve. Magma Draks create Cinderlings, Caustic Draks create Spitlings, Gloom Draks create Shadelings and Thunder Draks create Sparklings.
| Threat | Counter principle | Common mistake |
|---|---|---|
| High armor | Magic, true damage or armor reduction | Using only basic archers and physical melee damage. |
| High magic resistance | Physical damage and resistance-piercing skills | Assuming every boss should be burned down by mages. |
| Tower disable | Spread towers and keep hero damage available | Investing all gold into one central tower cluster. |
| Summoned enemies | Area damage and fast target priority | Focusing the boss while evolved adds reach the exit. |
| Unblockable movement | Slow, stun, damage-over-time and lane coverage | Depending on barracks alone to hold the boss. |
Exact tower choices depend on difficulty, unlocked upgrades and the stage layout. The counters above are principles that remain useful across Normal, Veteran and Impossible rather than a claim that one build wins every version.
Enemies and rewards
Enemy list, drops and encounter rewards
The base game has more than 40 enemy types, and later campaigns add their own families. The main enemy groups include Wildbeasts, Unblinded Cult enemies, Void creatures, Revenants, Crok enemies, spiders and special event units. Notable threats include Bear Vanguards, Turtle Shamans, Skunk Bombardiers, Cult Priests, Crystal Golems, Revenant Harvesters, Glarewardens, Leechfangs and evolving Draks.
There is no verified boss loot table that awards equipment, a random weapon or a guaranteed hero after a kill. Enemies still provide battle gold during the stage, but that is part of the normal wave economy rather than a boss drop. Boss victories can satisfy achievements that award gems; for example, individual achievements tied to Goregrind, Corrupted Denas, Mydrias, Navira and Abominor are documented with gem rewards. The exact reward can vary by achievement and difficulty condition.
The game does not include the older series-style encyclopedia as a main-menu feature. Instead, its enemy information is presented through encounter pop-ups, so the in-game description is the best authority when a patch changes an ability, resistance or reward.
- Confirmed reward types: stage completion, campaign progression, achievements and achievement-linked gems.
- Not verified: boss-specific equipment, permanent boss loot, random boss chests or guaranteed hero drops.
- Boss phases may create extra enemies, but those enemies usually reward normal wave gold rather than a separate boss bounty.
- Dragon Wars is version-sensitive. Its March 2026 balance update changed enemy gold values and several boss-related timings, so older videos can show different numbers.
| Reward question | Verified answer |
|---|---|
| Do bosses drop gear? | No boss-specific gear drop has been verified. |
| Do bosses unlock heroes? | No direct boss-kill hero drop has been verified. |
| Can bosses award gems? | Yes, through documented achievements tied to defeating bosses or meeting special conditions. |
| Does killing a boss give extra gold? | The normal wave economy applies; no separate universal boss-drop amount is verified. |
| Are boss stats permanent? | No. Difficulty, platform build and later balance patches can change values. |
Posts that describe guaranteed cards, weapons, hero shards or boss chests may refer to another game or an unofficial claim. Check the achievement screen and the current in-game stage rewards instead.
Planning
How long does it take to beat the game?
A first playthrough of the original campaign usually takes several hours, but there is no single reliable completion time. Replays for Heroic, Iron and higher difficulties can take much longer because each stage must be solved again with different restrictions. The post-launch campaigns add substantial extra time, especially if you are pursuing three-star-style completion goals, achievements and Impossible clears.
The practical answer is to budget one evening for a first campaign push and considerably longer for full completion. Failed boss attempts are normal: the biggest time sink is usually learning when a boss changes lanes, disables towers or releases evolved enemies rather than the length of the final wave itself.
- For a faster first clear, play the campaign before optional challenge modes and keep one flexible tower slot for the stage’s signature enemy.
- For completion, replay boss stages after upgrading heroes and towers rather than forcing a low-upgrade Impossible attempt.
- Use the official strategy guide for stage layouts, then adjust the build for the current patch if a tower, enemy or boss was rebalanced.
The developer does not publish an official average completion time. Any exact hour count is an estimate affected by difficulty, retries, DLC ownership and whether you are aiming only for the story or for full completion.
FAQ
Common questions
What is the final boss?
The Overseer is the final boss of the original campaign, fought in Hunger’s Peak. Later DLC campaigns have their own final bosses, so a player completing all current content will face additional end-of-campaign encounters.
Which boss is hardest?
There is no universal answer because difficulty depends on mode and upgrades. The Overseer, Abominor and Mygale are especially demanding because they combine phase changes with battlefield disruption, while Navira is dangerous if tower disables and Specters are not managed.
Can I farm bosses for gems?
Not as a repeatable boss-drop system. Gems are tied to achievements and other progression or reward systems. Once an achievement has been claimed, replaying the boss should not be treated as an unlimited gem farm.
What should I bring to every boss stage?
Bring a durable blocker, a source of physical damage, a source of magic or true damage, reliable ranged coverage and at least one crowd-control option. Save hero abilities for the boss’s transformation, summon wave or unblockable phase.
Why does my boss fight look different from an old video?
Difficulty, platform, DLC version and balance patches can change enemy values, tower positions, stun timings and rewards. Dragon Wars received a documented March 2026 balance update, so older footage may not match the current build.
