The Fight

what you are walking into

A giant Araneomorphus and the first boss most survivors meet. She webs, she poisons, and she spawns Araneo throughout the fight.

Her tribute is the three Island artifacts of the Clever, the Hunter and the Massive, which is why the caves that hold them are the ones every new tribe learns first.

what it can do, and what to expect

General

The Broodmother is the intermediate of the Guardians on The Island being stronger than the Megapithecus but weaker than the Dragon and while it does give you the least amount of rewards it's still best to fight the Broodmother after the Megapithecus and before the Dragon to help you better prepare for the Dragon fight. If you want to fight the Island bosses in lore order, start with the Broodmother first, with the Megapithecus second, and Dragon for last.

The Broodmother Lysrix is a dangerous enemy as It spawns Araneo as minions, slows players and mounts with its web attack, uses an acid projectile attack, and can cause torpor damage. However provided the right tames and equipment are brought to the battle, it can be defeated quite easily.

Dangers

• You can get caught off-guard if you're not on a dino, as the Broodmother has the ability to fire webs that slow anything down.

• Many of the Broodmother's and her minions' attacks, both melee and ranged, can induce large amounts of Torpor, quickly knocking out you or your allies if you're not riding a dino.

• On Alpha difficulty, Broodmother receives a significant buff to health and damage, requiring very high armor saddles, imprinting, and the Yutyrannus's courage buff. Make sure you have a strong breeding line of whichever dino you're bringing to the battle.

• The Megapithecus and its minions are also present in the Center Arena.

• On Valguero, the Broodmother can spawn in varying levels.

Weaknesses

• There is quite a large variety of creatures you can use in this fight that can be effective.

• The Broodmother is quite slow at gamma and beta difficulties.

• Megatheriums insect rage can quickly kill a Broodmother with little difficulty.

• Using a Procoptodon you can jump onto a mushroom in the arena and shoot the Broodmother with firearms solo without taking any damage (unless you're fighting the alpha variant).

How the fight works

  • Her web slows and roots you in place; ranged damage from a mount that can hold ground beats anything that needs to kite.
  • The Araneo she spawns are the real threat to a dismounted survivor rather than the Broodmother herself.
  • The arena has no cover, so the fight is decided by what you brought in, not by positioning.

Per map

what changes
  • The Center — Fought in the Center Arena alongside the Megapithecus — one summon with its own door, not The Island's: player level 70 / 80 / 90, all six of the two bosses' artifacts together, and a tribute of ten apex items (10 of each at Beta, 25 at Alpha, none at Gamma).
  • Valguero — Also spawns in the wild in The Lair, in the Redwoods — no summon needed. The wild variant does not give the Tekgrams the arena fight does.
  • Fjordur — Summoned from a terminal inside The Overgrown Grave, entrance at 57.5 / 65.8, and additionally requires 1× Beyla Relic at every difficulty.

Saddles matter more than levels here — 80+ armour Rex saddles turn Alpha from a wipe into a routine run. Bring a shotgun for the Araneo that reach a dismounted rider.
