Lot of good info here, thanks much.

Looks like the stats chart needs updating.
I'm rather new, so I'm working out what I want for a character and found at least 3 talismans that doesn't match.
Skilled, Sorcery, and Onslaught all have HP on the 3* talismans I have, but not the 2*.

Appears that they just added HP to the ones that didn't have it.
Don't notice any other differences, but I don't have the resources to max out a bunch of stuff, so I may be missing something.
