Yes, I did it. I am just silly enough to spend my hard earned gold on something as ridiculous as a polymorph: black cat tome.
I've wanted it for a while and have been very good about avoiding the temptation. I helped fund Aratria and Gabi's quick flight skill which was a lot of gold. I'm still sending Goldy regular bits of cash to help with her artisan skills. Today was the day though. I had enough staring at the tome and just decided to go for it.
Was it worth it? Oh yeah! Check it out. I ran out and specifically found a sheep to turn into a cat just so I could giggle at myself. Totally worth it.
