" Zagnoid may look like a science experiment gone wrong, but it's actually highly adapted to the sulfuric fumes that permeate Inferno. It has a keen sense of smell that leads it directly to defensive towers. "

General Information

This monster was first seen in Wave 32 of the Wild Monster Invasion and later on in Wild Monster Invasion 2. It appears to attack only defensive towers first, similar to Ichi and Crabatron. Furthermore, it deals double damage to defensive towers. It's health is also quite high - therefore it takes a long time to kill it.

Zagnoid's attack doubles when it attacks a defensive tower, and it is not a "researched" ability (like Wormzer splash damage or Bolt Teleportation, etc.).

Zagnoid is better than every single defense targeting monster in the upper world, and is very useful when transferred up. The reason is that it takes up very little housing space but has 3350 hp at maxed level and does 200 to defense towers. On the other hand, Crabatron has 4000 health but half the damage Zagnoid does to defense towers. It also takes only sixteen seconds to hatch, meaning you can make 46 zagnoid in the time it takes to make 1 crabatron and 5 in the time it takes to make 1 ichi. When used with a high level Fomor, it is almost invincible.

  • Zagnoid does double damage to defensive towers and Compounds, making it a good attacker, as you can send your high damage monsters in to dominate the yard.
  • Zagnoid is the Inferno equivalent to an Octo-ooze in the overworld.
