Boss and mechanic notes
The Lunar Subterrane has local boss notes for: Dark Elf, Damcyan Antlion, Memoriate: Durante. These notes are pulled from the local wiki and should be treated as source-backed prep unless separately marked as human-reviewed strategy.
- Hexing Staves: Summons two staves on two tiles of the arena, each telegraphing a plus-shaped AoE, leading to:
- Shadowy Sigil: Each tile will have a blue square or purple triangle, while an aura corresponding to one shape will emit from the boss, indicating which shape tiles are unsafe.
- Hexing Staves / Sorcerous Shroud: Causes the two summoned staves to disappear. Players will need to remember their original locations.
- Void Dark II: Spread AoE telegraphs on all players.
- Ruinous Confluence: The staves will reappear and resolve their line AoEs, which will be very briefly telegraphed.
- Hexing Staves / Sorcerous Shroud: Now summons three staves that disappear.
- The boss will then use both Void Dark II and Shadowy Sigil before using Ruinous Confluence to detonate the three staves.
- Staff Smite: Tankbuster
- Abyssal Outburst: Party-wide damage
- Sandblast: Party-wide damage.
- Landslip: Causes four "conveyor" markers to appear parallel to the pillars on the east and west edges of the arena. After a short delay, players will be pushed a distance roughly equal to half of the arena. Anti-knockback abilities will prevent the player from being pushed.
- Antlion March: Telegraphs multiple successive line AoE charges. During the charge, the antlion will target two of the Stone Pillars on the edge of the arena and crash into them, noted with an exclamation point appearing on them.
- Landslip is used again, but this time, any damaged pillars will collapse as a line AoE in front of them, so position to be knocked back to a safe area.
- Earthen Geyser: Stack marker on the healer. This also spawns a puddle of quicksand below the healer. Everyone needs to move out of the puddle before the Six Fulms Under debuff timer expires, or they will die.
