Amazing escalation overall, love the frostbite concept, even if it is a bit fast on the latest stages of 10-50 (the fight against urska isn't as enjoyable as it could be), and that encountering a shrowd/reza is equal to death 90% times.
Putting that aside, there are some bugs, especially the fact that powerboosts don't seem to work (I know it will be fixed), and that the 4th choice of amp turns into a choice of 3,2 or 1 at times (sad).
For balancing, I would point out the overall "defensive" turn that the esca has taken, a LOT (too much) of the amp are defensive ones that are in majority useless, and few of the offensive amp are viable (2% power or 3%crit is sooo little), it result that 50% of the choices are by default, which is in no way enjoyable. The fact that defense amp always appears with other defense amp doesn't help either.
Did not get to urska farming yet, but considering the massive farm needed for the paws, I would love either for the parts heal...
