Saves some time over just dunking in the acid, (dont try this at home), it's safer to go up until reaching the warp zone and then trying to get the stallball, just in case you fail. You'd need to take more soul or just go into the hornet 2 fight with less soul if youu go for it. Its also another way of going into the fight with full health if you get it. Still, prob more viable for a comsob or something.
