Are there only a limited number of components to upgrade your weapons with in the game? Also, is there anyway to get your component back out of an item after upgrading it?
The game does have a gem shop, except it's only accessible by paying for the expansion pack. It also has a wider range of gems to choose from (notably the Ruby gem which gives increased damage).
After multiple kazuro and shiori kills i have yet to get a shadow gem from them. So i use crystalds and emeralds(solidarity bonus 5% of vitality is added to other 3 stats). The emeralds give+5% vitality and +5% healing per stack.PS priest is easy, so easy that you can kill basically any boss without any effort, the hardest might be shiori since u might be too far to see if she is casting her gaze,tho logically shes always doing something,so... if there aren't green fireballs flying at you shes casting it.(unless you're close and shes running away from you).
Can you upgrade the components inside the weapon or armor? I kind of want my Ice to gain some more...stuff?
You can't upgrade components in a weapon because they are gone. And also, don't upgrade the Ice. There are much better weapons in the near future which you should use your gold/gems on.
there is also 1 crystal on the second level when you see bamboos get close to it and click the youll see a well and a ore you the picaxe the click the ore and youll get a crystal i hope this helps
