Selecting *any* of the orbs just has a greyed out "use x orb" option, as do all weapon/armors. So... no idea how to do it.
Likewise, there's an entire mechanic where you can invite various women to travel with you outside the city... and it does absolutely nothing. There's no content for it, and no apparent reason for it to exist.
There's also a couple of bugs with quest flags - I have broken Vulsha's vow and done all the Dragon adventurer content, but neither show as completed in the quest tracker.
Anyhow - full save (all skills learnt, all content done barring last Yennay potion as I can't work it out) as of vr 0.21
