Hello everyone,

some hours ago i got the "Ace's Mail" droped:
Status: STR+18, Atack+12 Acc+12.

As far i know gives STR about+1 or+2 to Atack, what is shown under equipment.
Atm i weare the Unkai amor set+2 what gives me a final atck of 753 with masamune lv 90. The Unkai Domaru (body) itsalve has no STR bonus up.

When i equip the "Ace's Mail" with it STR Bonus+18 i should have at last 771+ - whn i count 1 STR for 1 Atack. with other words it should be at last 771.

So here is my final question:
Why in Gods name i have just 753?

Can it be that STR bonus is capped somwhere on 99?
Can it be that simply not more Atack can be atained on a certain STR?
Please, i realy could use some advice...
