The Arachnid, a giant red spider-like boss mech towering over the desert

The Arachnid

BOSS 800 HP · PILOTABLE 650 HP · MARKED EXPERIMENTAL IN THE GUIDE-PAD

The Assembler cannot build the Arachnid. Use a Summoning Flare, defeat the boss, and repair its wreck. Then it is yours.

SUMMON · SURVIVE · CLAIM

01 · SUMMON

Craft an Arachnid Summoning Flare with 4 Titanium Ingots and 8 String. Use it in a clear 100×100 area. After a countdown, the boss lands.

02 · SURVIVE

The boss has 800 HP and sees you from 72 blocks away. It uses poison rain, a block-breaking plasma rifle (18 damage), and 10 missiles (16 damage each). Bring a mech.

03 · CLAIM

The boss leaves a wreck. Repair it to get a 650 HP Arachnid with two combat forms. It is the largest mech in the add-on.

Build a Mech in 6 Steps

Follow these steps from Titanium Ore to your first mech. The Guide-Pad also shows this path in the game.

Repair a damaged mech

WRECK → REPAIR

Damaged: use a Titanium Ingot for +10 HP. Use a Titanium Repair Kit for full health.

Broken: at 0 HP, the mech becomes a wreck. It is not deleted. Open the Broken Mech menu. Choose Repair Mech to rebuild it with its cargo, or Break Mech to take the parts. Operators can also use Creative Repair or Immortal Mechs.
