Quick Answer
Terrorbaum has damage gates between phases; shoot its eyes when you can damage it. Move away when it burrows, jump the emerging shockwave, and avoid its charges after it uproots. Defeating this Forest boss spawns a reward chest and opens the route onward.
Why is Terrorbaum not taking damage?
Terrorbaum has damage gates between phases, so you cannot finish the fight with one enormous hit.
A stalled health bar can be a phase gate rather than a reason to abandon your weapon. Keep aiming at the eyes until damage resumes.
Do not read the resistance values below as permanent invulnerability. They are separate from the confirmed phase gates.
| Stat | Value |
|---|---|
| Health | 13,000 |
| Fire | -20% |
| Frost, Earth, Charm, Bleed, Petrify | 100% each |

How do you beat the Forest boss?
Shoot Terrorbaum's eyes, handle its summoned enemies, and dodge the burrow before dealing with the mobile phase.
You encounter Terrorbaum at the end of the Forest. Interacting with it starts a short introduction, followed immediately by combat.
Aim at the eyes
Terrorbaum is a large tree covered in eyes. Shoot those weak points to damage it. Quickly eliminate the Craw, the flying crows it summons.
If you are choosing equipment before another attempt, compare the best weapons. Weapon choice does not remove the boss's phase gates.
Move away from the burrow, then jump
Terrorbaum can disappear underground and emerge beneath you. Move away as soon as that attack begins. Then jump over the shockwave produced when it emerges.
Treat the relocation and the jump as separate responses. You need to avoid both the emergence beneath you and the resulting wave.
Watch for the uprooted phase
After losing roughly 40% of its health, Terrorbaum uproots itself and moves around the arena. Watch for charging attacks and avoid getting trapped.
You now need to track the boss's movement while continuing to aim at its eyes. Do not assume the stationary opening lasts throughout the fight.
Leave marked ground before projectiles land
Terrorbaum launches projectiles upward, which later strike highlighted ground positions. Move away from those marked areas while continuing to shoot its weak points.
Its bullet rain also returns your own shots.
Which attacks should you recognize?
You face ground slams, roots, summoned Craw, burrowing, charges, and falling projectiles.
Use the attack cues to decide when you need to move or jump.
| Attack or cue | What you need to know |
|---|---|
| Ground slam | Terrorbaum delivers a heavy ground attack. |
| Roots | Roots shoot upward from the floor. |
| Summoned Craw | Quickly eliminate the summoned flying enemies. |
| Burrow | Move away, then jump the emergence shockwave. |
| Uprooting | Expect movement and charges after roughly 40% health loss. |
| Highlighted ground | Leave the marked area before falling projectiles arrive. |
| Bullet rain | The boss turns your own shots back against you. |
What does Terrorbaum drop, and where do you go next?
A reward chest appears in the arena, rolling possible rewards from Terrorbaum's dedicated boss loot table.
The pool favors high-tier weapons, with rare armor, accessories, and special items mixed in. You are not guaranteed every listed item from one victory.
| Reward group | Possible drops include |
|---|---|
| Weapons | Augusta, .357 Balthazar, Corpsemaker, Ferryman, Salamander, Star & Witness, Wyatt PULSAR |
| Armor | Camo Jacket, Pith Helmet, Ghillie Suit, Ballistic Helmet, Steel Helmet, Cowboy Vest |
| Other items | Insurance, Craw Guano, Delicacies of the Forest, Crypt Key |
If you find armor, use the best armor guide when comparing your equipment.
Your victory opens Shav'Wani Bridge, the route into the Fortress.
