im not sure about that +14 spear, its possible but as far as i know but it must have been a drop !!!
btw, +9 is 100% not the maximum, cause there was a guy on Venice, he made his 64 spear +10 and tried +11 and it failed ^^ but i saw the +10 spear in his stall !!
/edit: btw gandbusta92 is talking sh.it!! dont listen to him and brake your weapons, the alchemy thing is absolutly random and luck you can do nothin to improve the rate of successfull alchemy... all theese tricks the ppl are telling arised by a lucky alchemie try, it worked for them sometimes 2 or 3 times and now they think it works always and for everyone, but thats wrong
