HP Wash. need some information.

So I made a warrior and I want to HP wash him.. The thing is that it wont take none of my MP. Someone told me that its on my minimum MP for my level so I decided to check it out by adding 1 AP to MP. However, when I try to take 1 AP from my MP and add it to STR it just wont work.. like its bugged.
Can someone please explain what I'm doing wrong?
Or do you think its a bug?

 

Can you provide us with some stats? Such as your lvl, base mana shown by an ap reset and such .

 

Try adding 1 point into HP, there are no bugs with HP/MP washing.
To check your minimum MP click on an AP reset it will display your base MP without items.

There is also the HP washing guide with a minimum MP formula.
