Any chance you can change that about the spellbooks Sephi? I just sent an adept off half way around the map to get to an elemental spell book (to hopefully get scorch) rather than the one I wanted to learn the spells, so I could have that good spell caster to help defend against the Calabim... Damn annoying to find he couldn't take the spellbook!
Or is there a particular reason why you have it that way?
I forgot the reason, some weird limitation with the equipment system. Added now abilites to Drop these equipment. Should also solve the issue with capturing an Mana Guardian.
