Thank you for your feedback, I'll check for the queen Bunny,
Physsea is quite a strong opponent(she is the third general afterall :P) (but there is a lot of strong gear to found, it can help to beat her)
I'll look about nerf a little bit her heal, but this is 'beatable' (are you level max ? )
PS: try to use the fire bash skill and crystal magic sword, maybe it can help you :P
-Can you give me more information about the Queen bunny sounds bug ?
