In the Ava Straden magery guide (http://vboards.stratics.com/showthread.php?t=63848) is explained the boat training. It's said also "This method works for necromancy, spirit speak, music and peacemaking, chivalry, and all the other movement based skills". Well I actually train my bard in my home for music and peace without moving and it seems to work and I have not seen anything about that in the Liah guide. Did I missed something somewhere ?
