Does anyone know how many stones with percent possibility u need to make it 250HP? some Stamina Stones have % 10 some other have %30... but it is kinda hard to make it 250HP how does this really works?? cause sometimes i put 30% stamina stone and it gives me 100HP when i add another 30% Stone it fails and goes down to -50HP is this just all about luck??? or there is a way to make it faster 250HP(100%)?

Alchemy is based on luck. Sometimes it will take 1 stone to get (+100%), sometimes it will take multiple. The % on the stone is the assimilation %, the chance that another stat will be changed if the stone is successful. 10% is less likely to change another stat than a 30%.
