Need some help regarding HP Washing

Lvl ~ 75 White Knight
MP ~ 456

If the formula is correct for min. mp which is (4*lvl)+56, I still should be able to wash right? I still got 2 AP in my HP pool however, it's not allowing me to remove any mp anymore.

Now this would be fair if I'am a DK which follows (4*lvl)+156 = min. mp

Any ideas?

 

Are you sure that is your base MP you might have items that give you MP.

 

That's my base MP, does it make a difference if i have 20 base int? My total Int w/ equips = 110.

 

I don't believe int would matter. Just to be clear when you open an AP reset the MP shown there is 456?
That is the only thing I can think off.
I heard that some even was below min MP so i'm not sure how much you can trust that formula at early levels.

 

Yes, it shows MP ~ 456.

 

Anyway I tried to level up a few more levels and from 75 - 78, I was only able to wash three times per level. Now at 78, I have MP ~ 469 and it won't let me wash anymore.
