The Furnace Colossus

The Furnace Colossus: the briefing

What the game tells every player before this wave.

What it does

• Trample: every tower within 2.5 tiles of its path is crushed and stops firing.
• Furnace blast at 75 %, 50 % and 25 % HP: it stops, every tower within 9 tiles is stunned for 4 s, then it walks faster and heals more.
• If it reaches the goal, the run is lost.

How to beat it

• Sell behind, build ahead: every sale refunds 100 % while it walks.
• Before each blast, keep your strongest towers out of the 9-tile reach.
• Poison and slows work at reduced strength on it: raw damage wins.

Giant rules

• Trample: every tower within 2.5 tiles of its path stops firing for the rest of the wave once it has passed.
• Furnace blast at 75%, 50%, 25% HP: it stops for 4 s, every tower within 9 tiles is stunned for 4 s, then it walks ×1.15 faster and heals ×1.5 more.
• If it reaches the goal, the run is lost.
• While it walks, every tower you sell refunds 100%: sell what it has passed and rebuild ahead of it.
• Towers more than 6 tiles from it deal ×0.6. Slows work on it at 65% strength, poison at ×0.5.
• Its body is huge: a splash hit lands on it 2 more times, and a chain with nothing else to jump to hits it again at ×0.35.
• Each race's towers deal giants their own share of damage: Fire ×1.35, Frost ×1.4, Water ×1.2, Light ×1.3, Gale ×1.45, Storm ×1.25 and Arcane ×0.72.

What works against it

• Armour 15%: every hit is cut by that much, except true damage (Rime Shatter, Glow, Beacon, Pulsar, Flash, Judgment, Wrath and Smite and 5 more).
• It regenerates, so damage has to come faster than it heals. Slowed creeps regenerate at 50% of their rate.
