FF6T Fanatics Tower

-Most if not all regular encounters in the Fanatics Tower can be run away from - many were unrunnable in vanilla FF6.
-The boss no longer changes its elemental weakness in response to being scanned with Libra - in vanilla FF6 it would change in response to being targeted by any action (including scanning), so there was no way to actually tell what the current weakness was.
-The boss no longer casts Ultima as a final attack - this will kill you guaranteed in vanilla FF6 without some very specific preparations, and there's no warning that it's coming.
-Once the boss is defeated, the tower's magic field breaks and you're able to use physical attacks and other battle actions normally, making the trip down the tower much more pleasant.
