River Hag bubble mechanic feels out of place

Stop trying to homogenize every monster in the game to the same loot pinata slop. Once you remove hags you'll ask to remove then next more annoying unique monster.

Adapt, the only change that I would consider is making the bubble more visible, or the effect when you're inside the debuff more obvious, but don't nerf or remove it, it gives the game charm and personality.
