Out of all the spirit beasts, I think Skoll is my favorite. Awesome color/skin, and a fantastic lightning animation? So cool.
What's unusual is, the first time I tamed Skoll, it was on June 20, 2010.
And it just so happens that exactly one year later, June 20, 2011, I found him again.
(I already had him, and OF COURSE I couldn't kill him, so I told a guildmate, who came and got him.)
Will it happen a third year in a row? I intend to find out!
