At 0.7 seconds a swing for 90, sustained contact costs roughly 129 health per second. The charge multiplier takes it from 10 to 22 while closing.

Behaviour

Charges

Multiplies its movement speed while closing mid-range distance, then drops back to base speed on contact. Freezing effects are the only reliable brake.

Boss

Attacks on a 0.7-second cadence instead of the standard 1.1, and announces itself in the message log on spawn. One instance may be alive in its region at a time.

Drops

Coins and experience are awarded separately and are not part of the drop table.

Location

The Mad Inventor spawns inside the Gear Grind, a region of radius 19 centred on 300, -260. It occupies slot 3 of 3 on that spawn table, and being a unique boss it clears only 0.6% of rolls — and only when no other instance is alive. It shares the table with 3 other creatures.

Others on this spawn table

• Steam Spider 200 HP
• Clockwork Soldier 260 HP
• Boiler Brute 260 HP

Strategy

• Fight in contact or from well outside its approach band; the middle distance is where it doubles speed.
• Only one may be alive in the region at a time — clear the trash first so nothing adds mid-fight.
• At 90 a hit, two connected swings will end most unarmoured players. Armour matters more than damage here.
