Nexo Tower Fire Boss

3 ore boulders are here. Breaking one takes a Pickaxe or the Ultra Pickaxe. An ore boulder gives one of the eight elemental shards at random, or more with the Ultra Pickaxe.

A mined boulder comes back after 900 to 1,200 seconds of play, or 600 to 900 for ore with the Miner's Goggles.

Ranger 3 is fought here; its page has its rules.
