Another Sil'dihn Subterrane dungeon guide

Dungeon (Criterion) quick facts

The retelling of your adventures has set Osmon's imagination aflame with visions of perilous passages and mighty sentinels. He wonders, however, if dwelling in the damp has weakened the guardians; if, before rust and decay set in, that they had once been far more powerful. You cannot help but ponder the possibilities, your thoughts drifting as Osmon's hypothetical scenario plays out in your mind...

Boss and mechanic notes

Another Sil'dihn Subterrane has local boss notes for: Silkie, Gladiator of Sil'dih, Shadowcaster Zeless Gah. These notes are pulled from the local wiki and should be treated as source-backed prep unless separately marked as human-reviewed strategy.

• Fizzling Suds: Augments tail with lightning (yellow).
• Soap's Up: Triggers an attack from the boss depending on the imbued element. Since it always uses lightning first, it will initially release untelegraphed conal AoEs hitting the intercardinals from where the boss is facing, making the relative cardinals safe. This first usage mostly serves as a tutorial, as lightning was not present in variant mode.
• Dust Bluster: Telegraphed knockback ability inflicting minor physical damage. Can be prevented with sufficient shields or knockback immunities.
• Fresh Puff: Spawns three untargetable Silken Puff adds in a triangular formation. Two of them will be yellow (lightning) and one will be blue (ice).
• Bracing Suds: Augments tail with wind (green).
• Squeaky Clean: The boss will cleave a 90 degree area in front of it two times, then cleave a 225 degree area, leaving around a third of the arena safe. The safe spot for all cleaves is on the same side as where the boss initially starts. All Silken Puffs that are hit by the cleaves will have their element changed into the one the boss is imbued with. In this case, two puffs will become green (wind), while the third that was not hit will remain yellow or blue.
• Chilling Suds: Augments tail with ice (blue).
• Slippery Soap: The boss will target a random non-tank player with a line stack AoE marker and then charge at the targeted player. The remaining three players should be in front of the targeted player, or the targeted player will take lethal damage. Any Silken Puffs that are hit by the cleaves will have their element changed into the one the boss is imbued with. The stack AoE has additional effects depending on what element the boss is imbued with. Because ice is imbued, all players must be moving when they are hit by the stack, or they will be incapacitated for several seconds with Deep Freeze. After charging to its target, the boss will also release an untelegraphed plus-shaped AoE, making the relative intercardinals at max melee range safe.
• Carpet Beater: Telegraphed heavy-hitting physical tankbuster. The boss will also jump to the targeted player.
• Soaping Spree: Triggers the Soap's Up attack from the boss and all silken puffs depending on the imbued element(s).
• Lightning will trigger untelegraphed conal AoEs hitting the intercardinals from where the enemy is facing, making the relative cardinals safe.
• Wind will trigger an untelegraphed arena-wide donut AoE with a safe spot inside the hitbox of the enemy.
• Flash of Steel: High party-wide magical damage that should be mitigated.
• Specter of Might: Summons two clones (Gladiator Mirage) in the northeast and northwest corners. Each clone will glow 1-3 times, with a red glow meaning that the clone will keep glowing, and a yellow glow meaning the clone has finished glowing. One clone will always glow one more time than the other. Once the glows are complete, each clone will then charge a certain distance based on how many times it glowed and use a 180 degree cleave in front of it after stopping (Rush of Might). Immediately after the first cleaves, each clone will use a backwards 180 degree cleave, requiring the party to dodge into the area that was initially hit by both cleaves. The charge distance will be indicated by the lines on the floor. This mechanic will then repeat, with the clones now spawning in the southeast and southwest corners.
