Hi and welcome to FiestaFan! Feel free to introduce yourself at our Roumen port!
I have moved your thread to the Cleric section,
http://www.fiestafan.com/forums/forumdisplay.php?f=13, where you can find any useful information for yourself.
As to start off... well, what kind of cleric do you want to be? I'll list some very typical and generic builds to start you off:
Support/party-type of cleric
25 SPR/rest END.
Solo/damage cleric
Lots of STR/some END or SPR (I think).
I don't play a solo cleric so I don't know much about damage builds but I can help with a support type if you're planning to party a lot.
Not sure if you know yet, but the clerics in Fiesta are nothing like FlyFF. Clerics here are a lot more sturdier and can do some tanking and can even solo a bit if you go support build. By solo I mean kill some monsters and survive. But, it will be very slow if you try to solo with a support build (unless you enhance your gears and weapons to +9).
And. Clerics don't need INT in this game, so don't add any!
Feel free to post more specific questions so we know how to help you out.
