No longer able to. There was a campaign that you could buy for $5 during Halloween week that gave them out as a reward. They are not tradeable so you have to wait until next year... Or until the Greens give in and make them tradeable/attainable.
wait for halloween special ? (it was a limited time offer, a bug made it tradeable, but that was fixed) Normally the special campaign will be active again later(tm). After buying the campaign and completing legendary hardness, you'll get a blood owl.
Yup, totally a meta rune with one week of availability. I'm hoping they change it soon as I want to support the game, I suppose we will see how this comes out. I also wouldn't opposed to having the Renovator be switched into a blood owl clone. The art isn't as cool, but at least it synergizes better with UD. How are you guys changing your forum subtext to devotee of the blood owl.
Urgh, that kinda sucks. Been away for ages, and now can't get hold of a rune that will help my blood deck a lot =[ Curses!
