You have 3 stats to choose in Flyff, just go with the one which fits you well, and dont forget to buy the cheapest Flyff gold from Goldceo. ^^

Knights focus on STA: I turned to STR a bit, by which STA will be 15 points above STR. Well at higher levels you find that your attack is too low to kill anything quickly, then you use skills, they never miss and they have higher attack then your regular one.

Version A

(STA stays 20-25 Above STR)- This means Getting STR to 40, and STA to 60, Dex limit is 30! And once you get those just keep adding one to STR and one to STA each
level, so STA stays 20 above STR.

Version B

(STA is 15 above STR)- This version of the guide involves maxing out the STR to 50,making dex 28 dex (30 being the max for dex) and the rest to STA, this way you still have a good attack power when you are knight, and you still have alot of HP to take damage. This is also the path that I chose.

Version C

Same as version B except NO dex at all, since Knights skill spam at higher levels, meaning no misses with skills, dex is useless and the points can go to STA, do not like to skill spam 24/7, and you want higher hit rate until level 60 I recommend Version B, for the dex. Remember though you WILL be using alot of skills - meaning DEX has little influence on your char.
