What if you merged items A and B to make it look like B, then merged C and A(which looks like B), would it look like A or B?

Or can you not re-anvil an item that's been anvil'd?

When you anvil, you have two slots, the first slot is the item you want the item in the second slot to look like. You can use an anvil'd item to give its anvil'd appearance to another item. So in your example, C would look like B. You can continue to anvil as many times as you want, and you retain both items used, just the second one looks like the first one afterwards.

You can anvil cross class, but not cross item type, as in, no Top/Bottom to Overall, or a weapon to a different weapon.

Every time you use an anvil you get a use item, a black package, that gives you various rewards, like level 40 glasses, a mount, potions, scrolls, and, though I've only gotten the sword,old maple items that are 5 levels lower than usual.

So it works as long as the two items are of same category or is there a limit on what items you can turn into?

Ex.
Raccoon Mask > Spectrum Goggles
Kage > Elemental Staff 6
Dragon Tail Mage Sallet > Lionheart Battle Helm

?

Mhm, you got it.
