Holy shit that suggestion was awesome, thanks!Crit power works on your base damage, so the more you boost your melee and physical damage, the more effective your crit power is.
You might want to consider a Gryphon morph. It grants +40% crit power and +55 Physique (and +25 Arcane). Physique boosts your crit power and physical damage. At 70+ physique you get +15% physical and +30% crit power and at 90+ its 20% and 50%.
My suggestions come with a grain of salt. I love my unarmed melee builds and Physique is a big part of it, it isn't quite as helpful for a zweihander/sword build, but Physique is still a helpful boost.
Shielding is helpful, but if you are using an elemental in every fight, you can probably skip the shielding since enemies focus the elemental first. All of the serious fights do some fairly high damage, so unless you are stacking 50-100+ shielding you can probably ignore it for the most part.
Went from a Zwei-wielding Alicorn that did 900 damage on a crit to a Gryphon boxer with a crystal fist that deals over 1500 damage! (doing the boxing training in Pix's Playground really helped boost that unarmed melee build!)
P.S: Yes, I still have my elemental with me, she does around 500 damage per turn, since she can't be an awesome boxer like my char I guess she'll keep the Zwei lol.
