The idea of adding a chaos book to flavor things up a bit for mages has got me thinking. What's the chance of having certain mobs, be them rare zone mobiles or world mobiles that drew from a common pool of shinies and have them load out of a locked treasure chest? The items themselves would range from average to awesome, with the higher end having fast_decay, or no_rent as a compensation, but it'd also bring in a bit of excitement from the randomness to it.
I've not seen a similar mechanic in Arctic, though it's pretty common in a lot of other games that're both text or graphical, so it'd involve some definite coding. But in the end it might be fun and certainly the idea of loot pools could give creators an added resource in the future.
