There are definitely a fair few things that need a balance pass... Cold is hilariously powerful both just as being one of the best debuffs in the game, and for having a move which can deal absolutely nonsensical amounts of damage with surprisingly little setup. Meanwhile, basically everything associated with Venom chi is pointlessly impotent.
But then you have little oddballs here and there like the Star moves, or stacking the spike buff to ridiculous heights. And really, with just how many techniques there are and how spread out and varied things are, you basically do just end up brewing up your own wacky mishmash of a build as you go, making the best of what you've got.
Oh yeah, and there's that cursed sword skill that I randomly found at an auction... Which has its own scripted subplot and is basically a pact with Khorne that demands you shun all alliances and human compassion in favor of a cycle of endless bloodshed; but to compensate gives you completely busted power to keep the slaughter going. But if there's any sliver of humanity left in you, using it will devour you from the inside out.
As for just living life, running a tavern has been great and I love it. Everyone in Wuxia fantasy land is a lush, apparently. I've kinda been considering teaching my best customers the Drunken Immortal technique so they don't just pass out on top of my table after three drinks xD Ah yeah, and if it's not obvious, if you stock the table itself with food/drinks they'll get consumed, but it's considered basically as free bar snacks (even the wine). Popular, but they won't pay for it directly. However, if you have a wine shelf nearby, they can eat the stuff in the shelf from the bar table, and I believe that counts as a purchase. It can also supply all the tables around it, while putting food on/in a table wll only stock that one (I believe).
