During a battle in the Drake Hatchery, while I was choosing my cards, a text line appeared saying, "You used the hammer" and there was a picture of a drake egg. Next thing I know there's a drake saying, "Thank you, wizard!" All this happened in the middle of a turn. I'm not quite sure what happened, but it was defintely NOT supposed to happen.
Not sure if this has anything to do with it, but there were three Draconian Spellcasters (I'm not sure of their name), and a Fire Scavenger.
The Wizards were: 1 Balance (Lvl 46) 1 Ice (Lvl 47) 1 Fire (Lvl 35)
More like a bug with the voiceovers. I had similar occurrences whilst in the Crucible. It seems that the dialog for one wizard pops up for any and/or all wizards in the area. I would submit it as a bug and see if it gets fixed.
The same exact message appeared to me the other day, although I didn't see the drake. I don't remember the specifics of the duel when it happened though.
