Wow thanks for all that info. I'm not posting spoilers myself, just the odd hint, but it's great to see what other folks are finding out. Just a few things to comment on:
Hourglass? Nope, it does something else.
The death eye is really useful if you're playing as Lester, but it works for all characters.
There's no mythical creature to create in this game, sorry!
Sabre Wulf? Nah, not for me, one of my least favourite Ultimate games.
:o)
