So, According to what i know story wise through playing. Rhinestone, kept at bay by Lisk. says she'll escape and such since you kill Lisk in Lisk I. That being said i know it's possible to FAIL Lisk I and let her "escape" or so i've been told. Thing is.... and this is where the suggestion comes in. What would be an "escaped Rhinestone" fight? like... say for instance once every few days or whatever a variation of Rhinestone DOES appear in some map and well yeah encountered just like another world boss? Either through some random map spawning or just spawning around one of the high level maps i guess. Change her drops SLIGHTLY and up her abilities since Lisk is no longer controling her and send her on a rampage. I think it would be cool personally.
