The Dive Bomb Physical Umbral Blades (UB) Falconer in Last Epoch remains a strong and viable endgame build even after the 1.2.5 patch nerfs. This build excels at high Corruption runs, including clearing Corruption 1000, with a streamlined one-button playstyle that balances explosive burst damage and solid survivability Last Epoch Gold. 

The strength of this build lies in its unique synergy between the Falcon minion skills and the Rogue's melee abilities. Dive Bomb is used as a powerful burst skill where the Falcon descends from above, dealing devastating physical damage in an area. This damage is amplified by stacking physical penetration through Explosive Traps and the passive Sky Signal node, which provides unlimited stacking penetration buff on trap detonations, boosting the Falcon's damage output significantly. Umbral Blades adds strong shadow clone mechanics, multiplying the number of strike instances, which synergizes perfectly with the Falcon's dive for massive burst potential.

Post-nerf, the overall damage was fine-tuned by reducing some individual node effectiveness and fixing a bug that affected Shadow Falcons using unintended Featherfall abilities. However, the main DPS engines—like synchronized Dive Bombs triggered by multiple shadow clones, and fast cooldown recovery via Free Lofting Bird and United Assault nodes—remain untouched. This ensures that the build retains its fast-paced, fluid gameplay while enabling frequent, high-damage Dive Bomb strikes, making it formidable against bosses and large packs alike.

On the defense side, the build balances damage output with strong survivability layers. Smoke Bomb is essential for generating shadows needed to proc On Wings of Shadow, which triggers additional Dive Bomb attacks, while granting evasion and damage reduction via Silver Shroud. Players often opt for gear emphasizing elemental resistances, dodge rating, and damage reduction to thrive in high Corruption zones, with particular item choices like Ravenous Void Gloves and Orian's Eye Amulet providing vital protection and utility.

Gear and unique relic selections significantly impact the build's post-nerf performance. While the Shattered World relic remains the optimal choice for permanent haste and slow immunity, Gambit of the Erased is a solid alternative that offers dexterity and skill points for more accessible play. The Talons of Valor unique gloves enhance melee Falcon damage when triggering multiple traps and critical strikes, synergizing well with the aggressive offensive style. Additionally, the Siphon of Anguish amulet helps apply Doom for notable melee damage amplification on bosses.

In conclusion, the Dive Bomb Phys UB Falconer continues to dominate in Last Epoch's 1.2.5 patch, showing resilience to nerfs through its layered damage mechanics, high mobility, and robust survivability. It remains a build of choice for players seeking high-endgame progression that combines explosive AoE burst with single-target precision, and a fluid, one-button playstyle Last Epoch Gold for sale.
