Cobalt Guard
Cobalt Guard (Solar Eclipse) was previously removed from the game on the 26th of January 2022 as it was part of the Solar Eclipse Event, though it has been made available through the Sandbox mode.
It is not accessible anywhere else in the game, aside from in Sandbox Mode. This page will attempt to include information about both the version before removal and its re-added version.

Description
The Cobalt Guard was an enemy that appeared in the third and fourth night of the Solar Eclipse Event. Currently, it can be spawned in Sandbox mode. It had a very high amount of health and it walked somewhat at an below average speed. It also had defense, meaning you had to deal more damage to it.
Appearance
The Cobalt Guard had a dark violet crusader helmet, chestplate, leggings and shoulder pads. It had brown arm bands with white spots. Its arms were made out of black metal with hooks on its back. It walked with a slight hunchback.
Strategy
As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in the Solar Eclipse Event is listed instead.
- High DPS towers such as the Minigunner, Crook Boss or Ace Pilot are recommended against the Cobalt Guard.
- Towers that reduce defense of enemies, such as the Pyromancer, Electroshocker, Freezer or Frost Blaster can decrease its defense, allowing your towers to deal more damage to it.
- The Electroshocker, Freezer and Frost Blaster can also be used to slow this enemy down.
- Do keep in mind that the Pyromancer will increase the speed of this enemy by 15%.
