The Green Triangle is a Poisonous shape which may rarely evolve from Green Square or Triangle, or spawn in the nest of Triangle Sanctuary.


Green Triangles were added on 28 May 2018, and were given a 0.45% chance to spawn over squares. On the same day the chance was lowered to 0.35%. On 21 April 2020 they were given the ability to poison players if they touched them. As of March 10, 2020, Trimancers are no longer able to infect these triangles. On 26 April 2021 Trimancers can infect these shapes once again.


The Green Triangle looks like a green triangle and has a faint green aura around it.


Green Triangle has 60 health and gives about 2000 experience. Green Triangle will inflict poison effect for 7 seconds if touched by a player or AI.

Green Triangle may rarely evolve into Green Pentagon or Orange Triangle, though both are rare and it usually stays as a Green Triangle.


Green Triangle is a very good way for low-tier tanks to level up, since it gives a lot of experience. However, it is pretty scarce and not commonly seen. Do not try to ram Green Triangle, as it will inflict poison for 7 seconds. If you found nest of triangle sanctuary, you may get a lot of experience as a low-tier tank. However, this is a risky strategy because of Sentries. These shapes are slower than normal Triangles when infected by Trimancer.
