Shulk was dead, now he's not. There was some plot in there somewhere but I doubt it made much sense.
Next were several telethia to fight, which seemed scary but they turned out to be fairly straightforward battles.
Then it was off to the Bionis Interior. It's much bigger this time (well, technically there's much more accessible). Some new creatures and several higher level enemies that killed me once or twice.
Once I made it to the heart I met Disciple Lorithia who turned out to be very tough indeed. She was rated at level 75 and for my initial attempt I was just level 71. I got flattened quickly without doing much damage so I went for a levelling up excursion.
I now have side-quests for 5 improved Monados. Each requiring three items from tough monsters. I've started to collect a few but some of the creatures are level 90+.
Also along the way I discovered Tyrea who set me up with a surprise quest and a level 80 telethia to beat. This one turned out to be her mother.
I managed to reach level 76 mostly by killing hoxes and gogols on Bionis' Leg. I almost beat Lorithia at level 75 but 76 proved to be enough to win. Now I have a new black warp to step into...
