Revision 1

Basilus the False (위악의 바실루스) is the final boss of the Citadel of the Fallen Daeva, the level 50 Expedition added with Chapter 1. Lands of Sand and Snow on July 1, 2026, and the boss NCsoft featured on its official Chapter 1 site. In the official story the citadel's Daevas drove off a Balaur invasion with forbidden black magic, were corrupted by it, and now fight on inside the walls as if waiting for a death that would wash the corruption away. Everything here describes the Korean and Taiwanese service; NCsoft's global notices had not listed the Expeditions open in the global build as of October 7, 2026.

Mechanics

When the fight starts every player receives a black or golden circle, and the rest of the fight follows that colour. Basilus raises shields, and each player overlaps their own red pool with a shield of their colour to break it; player guides note that a player's ring appears on the side of the arena opposite the boss, so grouping by colour keeps the pools tidy. In his wedge attack players step into wedges of their own colour, and when his trial swords fall into empty ground each player steps into their own marker.

In Judgment Explosion (심판의 폭발) one marked player leaves the boss's reach while the other four stand on the remaining sword zones to absorb them. He also summons Fallen Daeva Guides (타락한 데바 인도자), and golden circles on the floor have to be filled before they detonate.
