A Level 1 Tank will need fifteen hits to kill a Green Square. This results in a reward of 66.67 EXP per hit.
If you manage to destroy a Green Square at Level 1, you will skip the next 14 Levels, instantly landing you at Level 16.
A Necromancer can make this Polygon one of its Drones by crashing into it or touching it with its current drones. The resulting drone will be exactly the same as a drone made from a Yellow Square. However, the green square drone will give you EXP when it is killed, unlike other drones.
When you are killed by this shape, it will say “You were killed by: Square” instead of “You were killed by: Green Square”, as they are practically the same thing, only the Green Square is much rarer.
The Pentagon has the same exact HP as the Green Square, which is 100 HP.
