O3S – Halicarnassus

Encounter Overview

Halicarnassus (Savage) is a multi-phase encounter built around panel-based arena transformations, forced movement, and layered mechanic combinations. The fight progresses through distinct themed phases, each modifying how core mechanics behave.

Success in this encounter depends on recognizing panel states, pre-positioning for forced movement, and maintaining structured assignments. Compared to normal mode, mechanics are tighter, overlap more frequently, and punish incorrect positioning immediately.

Arena Overview

The arena shifts throughout the encounter using Panel Swap, changing into themed layouts such as standard, forest, cave, and library configurations.

Each panel type alters how mechanics resolve, requiring players to adjust positioning and movement patterns depending on the current phase. Consistent role positioning and awareness of panel effects are critical to maintaining control.

Boss Mechanics

Halicarnassus

Critical Hit

A high-damage tankbuster that always critically hits. Tanks must mitigate consistently and remain prepared for repeated usage.

Spellblade (Holy / Fire / Blizzard / Thunder)

A rotating set of elemental mechanics that define positioning requirements.

• Holy: Combination of AoEs and stack markers, often paired with tether swaps.
• Fire: Point-blank AoE, requiring players to move out.
• Blizzard: Large AoE requiring players to move away from affected zones.
• Thunder: Line AoEs that must be sidestepped.

Panel Swap

Changes the arena type and modifies the behavior of upcoming mechanics. Each phase introduces different interactions tied to the environment.

The Queen’s Waltz

A core mechanic that changes based on the current panel type.

• Standard: Conal AoEs targeting all players.
• Forest: Tethers that must be broken by separating groups.
• Cave: Pillar AoEs with limited safe tiles.
• Library: Targeted damage requiring spread positioning.

Playing Field / The Game

Transforms the arena into role-based or status-based tiles. Players must stand on the correct tile to avoid heavy penalties.

Mindjack (Forced March)

Forces players to move in a set direction relative to their facing. Often overlaps with other mechanics, requiring pre-positioning before movement begins.

Place Token

Spawns adds that vary depending on the phase. Each add type introduces additional pressure and must be handled quickly.

Place Dark Token

Spawns tethered mechanics requiring players to position for maximum distance while staying within safe zones. Incorrect positioning results in lethal damage.

Dimensional Wave

Raid-wide damage that appears frequently throughout the encounter, adding sustained healing pressure.

Haste / Haste III

Speeds up subsequent mechanics, reducing reaction windows and increasing execution difficulty, especially in later phases.

Ribbit / Oink / Squelch

Status mechanics that transform players if mishandled. These are often combined in rapid succession during later phases, testing awareness and control.

Encounter Flow

The fight begins with standard mechanics and introduces Spellblade combinations alongside The Queen’s Waltz, establishing the base pattern of reacting to panel-dependent mechanics.

As the encounter progresses through forest, cave, and library phases, players must adapt to changing arena conditions while handling adds, forced movement, and overlapping AoEs.

Mid-fight sequences increase pressure through Mindjack and Place Dark Token, requiring precise positioning and coordination to avoid lethal outcomes.

The final phase combines all previous mechanics into rapid sequences, including mixed panels, chained status effects, and heavy raid damage. Execution consistency becomes critical as mistakes quickly cascade into wipes.

The encounter ends with a hard enrage if Halicarnassus is not defeated within the time limit.
