HeartKing

Summary
This tower was only obtainable during the valentines week event, and today (2/26/2021). Currently, he can do 1-7 damage (from levels 1-5) and has a range of 35, with a reload time of about 1.

Trivia:

 * He is the first event tower in Base Defense, Heart Queen not included as she just reskin of robo-hunter.


 * You required to use chocolate to get him, but not guarantee 2% chance, however if you had enough chocolates (From valentine), you could buy him some time later after valentine, for limited time. (But you can't get chocolates anymore in Limited time).


 * He is recommended to be used as mid-game tower for impossible mode, because at max level he can shoot air, and can make flying supporter robo friendly and its spawn too.


 * He has lowest damage, but when in numbers, he eats robos like butter with his "stockholm syndrome", except for boss.
