Good day @Baltmort

 

I apologize for the inconvenience. In order to progress you will need to battle all of the Aqua and Magma Grunts that you have access to. Once they have been defeated you will need to locate a key (the location of which is hinted via the grunt's dialogue). After getting the key, another barrier will drop, allowing your progression.

 

I hope this information helps and I look forward to hearing from you on your successful progression.

 

Regards,
