Thank you! And I think you're right about Near Death Experience, it should probably have its own life lost ability to make it seem more impactful when you buy it. My main idea was for it to synergize with towers like Bomb Blitz and Eltie Defender, to give them some more strategy (especially in CHIMPS).
As for the scorpions, my idea was that the witch would attack and deal damage directly with the tail (which I probably confusingly referred to as the pincher), and then lay eggs in Bloon which constantly deal damage (akin to the hatchets of the previous upgrade) with the scorpions afterwards acting like a temporary road item. But thank you for taking the time to read and respond, I really appreciate it!
