ok lets.. go
: Buy a lv. 50 Wind weapon, an Ability extracter from Tools Npc and a Resto Talic.
: Combine those 3 in Hero. Result will be 50 Wind abilities.
: Craft as normal until you get Knife Normal
: Combine the Knife normal, 15 Wind abilities, a Purple A Excelsior, a Belief Talic and an Ability combiner (or however it's called). Surprise! You've got a lv. 30 wind knife.
: Get a spec to lv. 40 and farm the materials needed for a lv. 30 knife.
see link this for material http://rf.mmosite.com/guide/crafting/weapon_knife.shtml
: Keep crafting them till you get an Intense 30 Knife.
: Combine the Wind and Intense Knives at Hero, adding a Type A Black Excelsior, and there you go!
