Guardian

The Guardian is a boss that was added on September 16, 2018.

Design
Guardian has a pink triangular base with a crasher launcher at the back.

Technical
Guardian has a very low speed and normal health. It spawns Crashers at a fast rate, which have low speed, health and damage.

Spawning
Guardian spawns if Xyv Wdtcfgzsezgk, a Crasher Sanctuary, a Triguardian, or a Quintet dies.

Evolution
If the Guardian is left alive for too long, it becomes PS3_33.

Countering
Guardian is one of the weakest bosses, so killing it will not be problematic. If it is near the Defender, try to eliminate Guardian first. If it is near Summoner, focus on killing Summoner and retreat until you will regenerate all your health. Bullet spam tanks, Machine Gun branch is ideal at killing the Guardian. If you are a tank with focused fire, just spread some bullets to eliminate incoming crashers. Focusing most of your firepower on Guardian will kill the boss very fast.

If it is near Defender, the battle may be slightly harder, but still easy. If you are a tank with focused fire, you will have no problems in killing Guardian, but it will take more time as the Defender will penetrate some of your bullets. As a tank that cannot deal steady damage to the Guardian, try to split Defender and Guardian apart, as Defender has slightly higher speed.

Trivia

 * The Elite Sanctuary used to spawn this on death, But now it spawns a Quintet on death.
