I think the safety bubble could do multiple things.
I think the Bubble should either make Murky invincible forever but the player can decide when to de-activate it when they press the skill again, when he collides with a player/minion he moves them and he can disrupt players from getting the tribute on cursed hollow.
I don’t know whether this should be another skill or the same but I think the safety bubble should be able to be pressed, the bubble activates and Murky becomes invincible automatically travels back to one of his eggs to regenerate.
I also think the bubble should have a different use, he presses it, he gets a shield, I don’t know how strong the shield should be, and enemies can pop it if they want and he can use the skill again as soon as the bubble is popped if it gets destroyed. Murky is an annoying twat but that’s the point of that character, he’s awesome.
But right now I think the Safety bubble is broken, it prolongs Murky’s life for some reason then he can continue to fight or die.
