Thanks for your help.
Any idea how to avoid the 'long marches' in the battlefields then (eg have I missed something in the wizards area) these slow down the game play too much when all I need to do is get the experience points and carry on with the plot.
Did not know till now that Yit-Ydra charms do not exist (bit of a snob over this: Yits are the only way to go - Uru, Ser, Min and Pags are only there as trading tokens for Yits) have spent most of Act II and nearly all of Act III hoarding gold and charms against finding a source of Yit-Ydras. It turns out that I could have been doing something more interesting - like turning out my sock drawer. Ho-Hum.
Thanks again for clearing this up.
regards
