@sdarkpaladin,
@ohguy, It takes some imagination to understand what's going on in that panel. My interpretation is:
Lovisa was going to say something along the lines of "Primitive tactics (swordsmanship) do not work anymore." (but she only started by saying "Stone Age's ...") then the Chimera sort of interrupted her with "GuGeeeee" possibly because it was offended (I don't understand Chimera language, sorry) then Lovisa corrected herself by saying "This is rather the age of magic and ingenuity/wisdom".
Since I'm not the author of the series, I have limited understanding of what's going on in the story, and that shows in the translation. I don't dare to add something that might cause a contradiction in later chapters.
