This just in! A Beta tester mentions off-hand that Treants have pet bars! Here’s the link. Decide for yourself! Hurrah!
1) He has tried the spell in Beta and know for sure we have pet bars
2) He read somewhere that there are pet bars and makes an off-hand comment in a forum thread.
3) Well, aren’t those the only 2 real options?
Sure would be nice if it was true.
