Tears of Metal Final Boss Guide: Reach and Beat Harold

Harold the Dragon is the final boss of the current three-Act Tears of Metal campaign. He waits at the end of Act 3, and defeating him awards the Dragonslayer achievement.

The most repeatable first-clear plan is to reach him with low Threat, preserve a single-target payoff and one defensive layer, then treat the second half as a pattern fight: close distance safely when Harold changes sides, avoid the landing scatter, take a short opening, and leave before the next three-hit string or fire breath.

Final boss quick answer

How to reach Harold more consistently

The final boss attempt begins on the campaign map. Every optional detour can add resources, but it can also cost health, units, time, and Threat.

Use the shortest practical route through each Act when the build already clears normal battles. Take a detour only when it solves a specific final-fight problem: healing, a working single-target Emblem interaction, a necessary army replacement, or a reliable Threat reduction.

Before selecting Harold’s node, confirm:

1. Wallace, Brienne, or Ruadh can survive one mistake without the run ending.
2. The build has a short boss-damage route, not only wide crowd control.
3. One Dodge or defensive resource can be reserved for the sweeping laser or another forced movement check.
4. The battalion can clear nearby pressure without dragging the camera away from Harold.
5. Threat has not been raised for rewards the build no longer needs.

One Trial-level player reported that shortest-path routing plus every available Threat-down option produced a zero-modifier Harold attempt. That is a community strategy, not a guaranteed map route, but the principle is sound: do not make the final fight harder merely to collect another unrelated reward.

What Threat adds to the fight

Launch-build data lists five escalating Harold modifiers: increased health, resilience, damage, falling Dragonstone, and Mother Stone energy rays. The exact threshold and value can change with patches, but the final two illustrate why high Threat is especially dangerous: they add floor and lane pressure while the boss is already moving between melee, breath, and projectile patterns.

If an opening overlaps a falling hazard or energy ray, abandon the opening. Preserving the run is worth more than one extra combo.

Phase 1: block or move, then take two or three hits

Community clears agree that the first half rewards patience. With Wallace or Brienne, players report taking a couple of hits, returning to Block, and repeating. Ruadh’s lower Block stamina makes pure guarding less comfortable, so spacing and healing matter more.

Use Phase 1 to learn the end of Harold’s sequence:

• stay where both the boss and open floor remain visible;
• do not begin a long combo after the first slash;
• guard ordinary pressure only while Block stamina is available;
• move or Parry the attacks that break a held Block;
• take one compact punish after the final animation.

Extracted attack data identifies Jump Slam, the Meteor Shower projectile, and Spread Projectiles as block-breaking attacks. Paper Cult’s July patch made boss block-breaking attacks parryable, but a missed Parry is still a high-risk first-clear choice. Dodge or positioning remains the safer answer until the timing is familiar.

Phase 2: follow the side change safely

At roughly half health in the launch-build data, Harold’s recovery gaps shorten and his arena movement becomes more demanding. Current player reports describe a repeatable cycle:

1. Harold moves or flies to a side of the arena.
2. Close distance without spending the Dodge needed for his sweeping laser.
3. Leave the landing area and its scatter.
4. Take a brief opening while watching for airborne projectiles.
5. Move out before the three-hit melee string or fire breath.
6. If fire breath begins, sidestep and punish from the safe side.
7. When Harold leaves again, reset and repeat.

Do not wait passively in the center through every ranged pattern. Experienced players report that the accumulated projectile pressure eventually chips the run down. Advance through visible safe floor, but never turn a safe approach into a blind chase.

Build for Harold, not only Act 3 mobs

Wide effects can make the route comfortable while contributing little to Harold. Before the final Act, preserve at least one effect that scales single-target damage and one survivability choice.

Good functions to bring:

• a setup Wallace, Brienne, or Ruadh can apply during a short opening;
• a Heavy, finisher, Direct-Hit, or command payoff that does not require Harold to stand still for long;
• maximum health, damage reduction, Block recovery, or healing;
• enough crowd control to keep an escape lane open;
• a battalion command that can damage the boss without locking the hero in place.

Vortex-style grouping is useful on the route but contributes little when Harold is the only meaningful target. Do not delete all crowd control, but stop adding more once the army can already clear the nearest reinforcements.

Hero-specific plan

Wallace

Wallace is the simplest first-clear choice for a block-and-punish rhythm. Use Light → Light → Heavy only when the final hit will land before Harold turns. If the equipped weapon changes that route, check the Wallace weapon table before the run.

Brienne

Use movement to preserve Direct-Hit momentum, but do not chase through projectile lanes merely to avoid a reset. A shorter safe opening is better than losing the run to one greedy extension.

Ruadh

Ruadh is unlocked after Iseult and can make a first Harold attempt during a later campaign. His lower Block stamina makes spacing and healing more important. Save movement for forced attacks rather than using it to begin every punish.

Solo and co-op

In solo, keep Harold on-screen and clear only the enemies that close the escape lane. An intact archer or command setup can add damage while the hero waits for a safe entry.

In co-op, spread into a loose arc. The targeted player moves Harold away from revives and open floor; the other players clear nearby pressure and punish after his attention is committed. Do not stack every player behind the same Block: one target change can drag a breath, laser, or melee route across the whole group.

Harold is invincible or stuck

Paper Cult fixed several cases that could leave Harold invincible or stuck in version 0.11.57863, including a multiplayer interaction with the Crusader’s Purifying Light passive and Harold’s laser animation.

If the health bar does not move during a clear opening:

1. stop spending limited Specials and commands;
2. wait for the current animation or phase transition to finish;
3. confirm every co-op player is synchronized;
4. update to the current standard build;
5. restart the encounter if the state never clears;
6. verify installed files before the next full campaign attempt.

Common reasons a final-boss run fails

• Arriving with high Threat after taking rewards the build did not need.
• Building only for crowd clear and bringing no single-target payoff.
• Spending Dodge to close distance before the sweeping laser.
• Attacking after the first hit of Harold’s three-hit sequence.
• Waiting in the center through every Phase 2 projectile pattern.
• Backing into the arena edge until the camera hides safe floor.
• Continuing to spend resources while Harold is visibly invincible.

Frequently asked questions

Is Harold definitely the final boss?

Yes. Harold closes Act 3 in the current Early Access campaign, and his defeat awards Dragonslayer.

How much health does Harold have?

Launch-build game-file data lists 15,000 base health. Treat that as a version-sensitive reference rather than a permanent value; Threat, difficulty, resilience, and later balance updates affect the actual fight.

Can Harold’s block-breaking attacks be parried?

Yes on the patched standard build. Paper Cult explicitly changed boss block-breaking attacks so they can be parried. Dodge remains safer until the timing is practiced.

What should I save Dodge for?

Current high-Trial player advice specifically recommends preserving Dodge for Harold’s sweeping laser when using Wallace or Ruadh. Other patterns can often be walked out of, blocked, or answered with positioning.

What happens after defeating Harold?

The current three-Act campaign ends, Dragonslayer unlocks, and the run returns to late progression and future campaigns. Use the achievement guide or secrets guide for post-clear goals.
