Decagon

The Decagon is a removed polygon.

History
The Decagon was added at August 5, 2018. The Decagon was removed in the late 2019.

Design
The Decagon is a large orange decagon that is about as large as an alpha polygon.

Technical
The Decagon has 600 health and gives about 25,000 experience upon destruction. It can only evolve from Nonagon with a 1% chance and cannot evolve further. Decagon has higher resistance compared to Nonagon, that's why it is noticeably harder to kill.

Strategy
If you have reached the highest tier and have a high DPS, like Splitter, you can destroy Decagon for its experience. As a tanks with lower tiers, you will unlikely be able to destroy Decagon without wasting too much time. You can also use Decagon in defensive purposes against Bots, if you are unable to defend by yourself. In this case, you can move behind Decagon and trick bot into ramming Decagon and taking massive damage. This will force the bot to retreat.
