I'm running a medium armour nightblade.
7 pieces of medium armour gives me 21 from the dexterity passive.
then 3 assasination skills slotted should give me 9 from pressure points.
plus 2 from a weapon.
which should give me 32. but the character screen tells me i have 30. earlier it said 28 and i changed nothing. it's this just a visual bug or something else?
