I meant the success rate is governed by alchemy, not nat sube, right ? --[[User:Azzu|Azzu]] 11:23, 30 March 2007 (CDT)
AFAIK, Nat Sub mainly controls the success chance of these items, as they are created using this skill. Alchemy, it being the parent skill of Nat Sub, has some minor influence on the success chance. Assuming nothing is bugged. [[User:Manny|Manny]] 17:38, 31 March 2007 (CDT)
