I have 3 crystals banked. And 4 that I cracked open. As Poo said, I use them with my bards and they are wicked effective on those 2 full bards. When I needed my imbue'r to get the points for The Queen's Forge, <long ago> I transferred one to him and waited for it to bond. He's a pure crafter with the only real defense is to fly away like a little girl with his stone skirt pulled over his head. Once that vollem bonded, I was amazed how fast I got the points to use that forge. As for the bards, I will never raise them, period! All 4 are 2 slot so they can run with 2 and still be mounted with an ethy. Before all this Orc garbage on the seas, I used my bard with 2 of em to rip up merchant ships for resources. No more chopping, no more digging. Great non-tamer pets the way they are!
