At level 57 I think my witch AP of 128 may be on the low side. So I went to see about an upgrade and the forums are saying the best staff is Kzarka. I looked at it with 18-22 AP versus my Black Abyssal Staff at 77-91 and wonder why is it better? The Kzarka says Enhancement fixed so I do not even know how I would upgrade it. Can someone tell me what the ultimate AP is for the Kzarka and how I would upgrade it? (P.S. I am very new to this game and generally confused about many things including weapon or armor upgrades.)

Blackstones upgrade it but its better to just use what you have for now from quest and google / YouTube for help. Then on the 22nd do the new season as getting full pen on seasons should give u around 240-245 ap and 301 dp

Can you explain a little more about seasons? I first started on seasons and within a few days seasons ended. Then I found that the weapon I got and was using in seasons was no longer valid on a regular server and I had to spend what little silver I had to get a new weapon. What is going to be different? Are you saying if I get a Kzarka in seasons it will still be good in the regular servers? 

You can convert season gear into non season one after graduation/season end, also you can echange season gear if fully enchanted into tet boss gear set(non sellable one) one time so basicly as somebody already mention you can end the season with roughly 240ish ap/300ish dp and than use that gear after converting it on normal servers.

Clearly you are new so i wud suggest looking at a few guides or if you are in a guild ask somebody there to explain it more in detail.
