I bought Dreamlike Swiftness (increase max AGI by 5 per levels) today and I noticed that each time that I bought 1 level of "Dreamlike Swiftness (DS)", my displayed AC, Mana and Endurance decreased. My displayed AC was 5992 before I bought any DS. After I bought 5 levels of DS, my displayed AC was downed to 5968
I have 0 buffs on me before and after buying 5 levels of DS
Before --- After
AC - 5992 --- 5968
Mana- 34494 --- 34005
Endurance - 33739 --- 33423
I also bought 5 levels of "Dreamlike Fortitude (increase max STA by 5 per level)" and my HP did not increase any.
