Completing the Borderlands 4 campaign is only the beginning. The real challenge starts in Ultimate Vault Hunter (UVH) mode, where the enemies get harder, loot gets better, and each encounter tries your build to the limits. UVH is divided into five ranks, each increasing difficulty but enhancing rewards. Players advance rank by rank through special missions, bosses, and Wildcard challenges.
Ultimate Vault Hunter Rank 1


Rank 1 Stats:
- +150% Enemy Health
- +12% Damage Taken
- +20% Cash & Eridium
- +10% XP
- Better Loot Quality
- Elemental Affinities intensified
UVH Rank 1 is unlocked as soon as the story epilogue. Lilith will guide you towards four missions:
- Zane’s Firmware
- Big Encore
- Maurice’s Bounty
Wildcard: Rush the Gate
The Wildcard mission concludes in a battle with Sol, which has Healthy, Vampiric, and Regenerative modifiers. Completing this automatically unlocks UVH Rank 2.
