Stinger

the only way to get Stinger is by purchasing with gold?

you can also get stinger as a reward for inviting people to play the game. when those friends reach a certain level you get the stinger. It used to be in the branch task list but I dont see it anymore.

you must invite 5 friend and all friend reach level 10

task name is elite friend - 5

but idk how to get second stinger

the second one would have to be with gold i guess
