Matriarch Arachna

A multi-phase spider raid with webs, eggs, and swarm pressure.

Matriarch Arachna is a multi-phase spider boss encounter built around poison, web mechanics, and escalating swarm pressure. She spawns inside a pre-built arena that FAWE pastes automatically on activation, and fights through three distinct phases as her health drops, each one harder and more chaotic than the last.

Spawn Command

/mm egg get MATRIARCH_ARACHNA

FAWE Arena: The arena pastes automatically when Matriarch Arachna spawns. Make sure FAWE is installed and your server has write permissions at the spawn location before summoning her.

Meet the Matriarch

Phase Breakdown

Phase I. The Hunt Begins

100% to 65% Health

Arachna fights defensively, using the web architecture of her arena to her advantage. She launches poison volleys from elevated positions, plants Egg Sacs around the outer ring of the arena, and sends her Brood Minions to harass players up close while she repositions.

Poison volley. Multi-directional toxic projectiles
Web Snare. Roots a player in place for several seconds
Egg Sac placement. Scattered across the arena, hatch if not destroyed
Brood Minion swarm. Weak individually, dangerous in numbers

Phase II. The Web Tightens

65% to 30% Health

Arachna calls on her Clones and her personal Leader-class Arachna to join the arena. Clone variants fight with the same moveset and can be hard to distinguish from the real one without careful attention. Venom concentration in her attacks increases significantly. Poison stacks hit harder and faster in this phase.

Clone spawn. Multiple false Arachnas enter the fight
Arachna Leader. A named elite that fights independently
Accelerated Egg Sac hatching. Eggs that weren't destroyed in Phase I begin hatching now
Web Cocoon. Wraps a player fully, requiring teammates to break them free
Poison Nova. Wide-area burst centered on Arachna

Phase III. Matriarch's Fury

30% to Death

The arena becomes almost entirely covered in webs. Movement is severely restricted and Arachna drops her positioning games to charge directly at the highest-threat player. All remaining Egg Sacs hatch simultaneously at the phase transition, flooding the arena with spiderlings. The Matriarch herself enters a berserk state. Increased speed, faster poison application, and a new Venom Flood skill that coats a large area in lasting poison clouds.

Berserk. Speed and damage increase significantly
Mass Hatch. All surviving Egg Sacs release spiderlings immediately
Venom Flood. Large persistent poison cloud zones
Web Collapse. Snares every player in the arena briefly at transition
Matriarch's Wrath. A channeled multi-target attack that ends Phase III
