Xenobia is certainly not the tanky type you want calling the shots in the party so she will definitely need a tactician telling her where to go and what to do or she is likely to inadvertently pull too many enemies at once because of her added reach and inability to deal focused single target damage.  She was made with the idea of 'off tank' in mind which granted usually just means she needs more of a support mage than a blast mage or she won't be able to hold the agro of the enemy being focused by the rest of the party.<br/><br/>As for a profession as the type more likely to go exploring I was thinking about her being an herbalist.
