Easiest / Cheapest way to get +5 Agi?

[Meeshmaw]

As you may have assumed from the title, I have neglected to put 5 agility into my dwarven paladin as I am a nub

I have come to realize why this is bad. I'm level 11 and there is no turning back. I'm attached to the character and am not going to reroll. What is the easiest / most cheapest way for me to get +5 Agi and meet that baseline?
