Green Square

The Green Square is a poison-inflicting shape that spawns rarely in place of Squares. It has more health and gives more experience when killed. It can rarely evolve into a Green Triangle or an Orange Square.

History
Green Squares were added on 28 May 2018, and were given a 0.5 chance to spawn over squares. On the same day the chance was lowered to 0.4%. On 21 April 2020 they were given the ability to poison players if they touched them. As of March 10, 2020, underseers are no longer able to infect these squares.

Design
Green Squares are bright green squares with a pale green aura surrounding them and enhancing the color.

Technical
Green Squares have about 20 health and give 100-300 experience. The shapes inflict poison damage on the opponent for 5 seconds if touched by a player or AI.

Green Squares rarely spawn over squares, but also spawn in Square Sanctuary Nests. They can evolve into Green Triangles or Burnt Squares, though both are rare and it usually stays as a Green Square.

Strategy
Green Square is a pretty good way to level up as a low-tier tank, as it does not have much health and gives a lot of experience. However, considering its rarity, it is not very effective way to level up. Do not try to infect this square as an Underseer branch tank, as it cannot be infected. If you spawned near Square Sanctuary as a low-tier tank, you may consider eliminating all green squares for experience.
