Yhvh

Yhvh is the real final boss of Lucid Blocks. It is not a biome vermin and not a random world event. In a normal save, the route opens only after all 13 rosary beads are filled and the next Naraka cutscene block shifts into the ending sequence.

The fight changes by phase. Storm phases call comets. Hand phases bring the arm down for heavy knockback melee. Later phases add long-range bolts and archangel summons, and the pace climbs again in the last stretch.

Losing the fight sends you back to Naraka without clearing the beads, so the route is retryable. Winning marks the save complete and grants the End Game achievement.

Yhvh has no normal loot table. The reward is the ending itself.
