How to Find Bloomreaper
After beating the story campaign, head to any major hub’s new Raid Board. Accept “The Wrath of Bloomreaper” and follow these steps:
Fast travel to Belton’s Bore in Cuspid Climb, then navigate to Tonnage Peel in Carcadia Burn. Enter the loading zone called The Bloom—you’ll unlock a fast travel point inside. Fight through the linear path (or skip enemies by gliding around them) until you reach the boss arena.
Battle Mechanics Breakdown
Phase 1: Bloomreaper stays rooted with purple Vile Armor protecting it. Destroy all Vile Crystals around the arena, then eliminate the pink orbs that spawn from each crystal—otherwise they’ll regenerate. Watch for AoE knockback attacks while clearing adds.
Phase 2: After destroying crystals, the boss bursts from the ground and blankets the upper platform with deadly thorns, forcing you onto lower platforms. Now Bloomreaper becomes mobile, jumping between platforms and firing devastating purple laser beams that knock you off edges. Stay one platform away, use your grapple-lash to maintain positioning, and keep gliding sideways to avoid projectiles.
Phase 3: The thorns clear, but a sandstorm reduces visibility. Bloomreaper intensifies attacks with more adds and faster movements. Keep circling and maintain aggressive damage output to finish the fight.
Legendary Loot Rewards
Defeating Bloomreaper drops exclusive legendaries, with better rewards for faster completion times in Ultimate Vault Hunter Mode. The Rainmaker sniper rifle is guaranteed for Platinum-tier clears (under 90 seconds in UVHM), while class mods drop for Silver-tier or higher (under 4 minutes).

Pro Tips for Success
Bring a high-damage weapon with good accuracy for crystal phases—splash damage isn’t necessary. For the mobile phases, prioritize mobility over raw DPS. Keep at least one enemy alive for Second Wind opportunities, and always save your strongest abilities for when Bloomreaper is vulnerable. Beating this boss on UVHM5 unlocks the brutal UVHM6 difficulty tier.
Can I solo Bloomreaper the Invincible?
Yes, but it’s extremely challenging. The boss scales to party size, making it technically soloable at level 50 with optimized builds. However, the fight is designed for coordinated teams, and having 2-4 players significantly increases your survival chances and completion speed.
What’s the fastest way to farm Bloomreaper for legendary drops?
After your first clear, use Moxxi’s Encore feature (costs 100,000 cash) to instantly restart the fight. Focus on UVHM Platinum-tier runs (under 90 seconds) for guaranteed Rainmaker drops. Optimize your build for burst damage and practice the platform movement patterns to shave off seconds.
