Holy shit I suck at this game.
One day I will get through a fight without fatalities, but today is not that day ;p
It gets a bit easier as you go. I petered on out this. I'm not sure how good, if any the post game is.
Character/skill progress ran out before the story missions did. So, I didn't feel much reason to keep going, and even finish any story.
the first arena fights are tough. Because its the first time you fight player like class hybrids, and party comps.
Some classes are way better then others. Both comboing skills, and stat gain.
warmage/marked is a strong combo for kyrie. focus on magic a bit over attack.
I went with templar focus for anadine. aoe attack buff. the def based attack starts strong. but then the righteous blow, and cleasning blade for mega kills.
dw gunner/bounty hunter for that chick. I like her better then the dude.
an alchemystic. just that. doesnt scale with shit... no point in even scaling its stats. just going to spam mass barrier, haste, renew, etc.
a princess-mender. both abilities, and stat scaling.
a sorcerer. a few ways to do them. note, lich, etc has better stat scaling, so will need to farm up stats. you can give em mana start, regen, and/or half mana cost, or blood magic, and have your princess/mendor feed em life.
There is a sort of juggling, good skills/build with farming stats with less ideal builds.
