I'll explain better..
1) use cheat engine..attach it at l2. (google it if u dont have it)
2) search in the exact value the NUMBER OF UR ENCHANT+1 (example: if u have weap +5, search for 6; if u have weap +44, search for 45)
3) change it to anything u want..+65535 or anything, meh.
thats just a client side hack. nothing of important.
