Location of Bramblesong in the Bittervein
Step #1: Finish the required story mission to unlock Auger Mines
Complete Main Mission 11 — Shadow of the Mountain. Abandoned Auger Mines become available only after that story progress.
Step #2: Open your map and mark Stoneblood Forest (Terminus Range)
On the world map, zoom to the Terminus Range region and locate Stoneblood Forest — Bittervein sits inside that zone.
Step #3: Travel to the Stoneblood Forest safehouse or nearby fast-travel point
Fast-travel to the nearest safehouse or waypoint and head toward the north/central cave markers in that subzone.
Step #4: Locate the Bittervein Abandoned Auger Mine entrance
Look for the Abandoned Auger Mine icon or a cave opening labeled “Bittervein.” Entrances can be tucked behind cliffs or doorways — move along the map edge and watch for an unmarked opening if the icon is not prominent.
Step #5: Enter the mine and clear the path to the boss chamber
Fight through the mine’s enemies, use cover, and follow the tunnels until you reach the boss arena at the end — Bramblesong waits past the final cavern. Use your equip abilities to make way to the last cavern.
Step #6: Recommended readiness check before you engage
Aim to be around the level range suggested for finishing the related main missions (players typically reach these areas around level ~18–20 on an initial playthrough) and bring healing, elemental options, and mobility tools.
Defeat Bramblesong (step-by-step combat guide)
Bramblesong is an oversized kratch-type boss with large reach and multiple flesh health segments — bring mobility, status effects, and burst DPS.
Enter the arena and immediately note cover and sight lines
You need places to duck behind when it winds up big melee or area attacks. Position so you can sprint wide and flank.
Learn its tells before committing damage windows
Watch for wind-ups for leaps, swipe attacks, or projectile spawns. If it telegraphs a leap or roar, back off laterally — its reach is large.
Apply elementals and status that punish its type
Incendiary (fire) weapons pair well with its flesh-bar phases; burn ticks both add damage and force movement that creates openings. If you have weapons with DOT or slow effects, bring them.
Use burst DPS when it staggers or is grounded
Save your highest-damage clips, ordnance, and action skills for moments it’s knocked down or immobile — those windows are where you chip whole segments of its health.
Maintain mobility — don’t plant and spray
Because of wide swipes and reach, strafing and short bursts of movement keep you alive. Use grenades and movement skills to create space.
Watch the final phase for aggression spikes
Bosses often add new attacks as their last health bar drops — anticipate a desperation pattern and keep your best defensive cooldowns available.
Additional practical tips
- Co-op makes the arena easier by splitting aggro — bring a partner if you’re farming Convergence.
- If you’re after legendaries, run the mine in Encore/UVH modes for better loot rolls.
- If you die, note which tells you missed and return with a focused loadout (incendiary + knockdown/burst weapons tend to be highest-value for this fight).
Final takeaway: clear, beat, and farm Bramblesong with confidence
You unlock access to Bittervein by finishing Shadow of the Mountain, then travel to Stoneblood Forest (Terminus Range) and enter the Bittervein Abandoned Auger Mine to reach Bramblesong. The boss is a large kratch-type with multiple flesh segments and phasing behavior — bring incendiary/status options, mobility, and saved burst damage to capitalize on staggered windows.
Kill Bramblesong to complete the “Song’s Over” requirement in UVH progression and to get a chance at the legendary Convergence and SDU rewards. If you follow the location steps, use the preparation checklist (heal, elementals, mobility), and execute the combat steps above, you’ll turn Bittervein into a reliable farm spot for gear and progression.
