Honestly, I'm not sure how strong I am either. Last tower I only cleared up to 6th floor (I think I had to use 3 keys to clear it, too...) I have gotten stronger since then, and unlike last time, I actually started farming fire SR assault weapons ahead of time and slvl them up a bit so it won't be like my fire team hits for like a fraction of my light team (which is what happened to my thunder team last time round.) I guess I will play it by ear.

In any case, good to know that I am not missing anything obvious with Acala, thanks!
