Ama, DreamerGhost: Creations added to list. Chronological order isn't that significant, so it's fine. The main thing including timestamps does is it allows me to search for the creation far more easily.
$$$Response
Magical sapphire spear of ice: Is it made of sapphires or is it made of ice or is it made of both? What does it do?
Uncreation: Roughly creation cost with upgrades
The entity known as Tykki will be permanently uncreated. Ununcreating spawns an ever-so-slightly different clone (seeing as the unique template was uncreated, there wouldn't be a significant price hike). I think this balances not restricting actions and preventing cheap tricks sufficiently well.
Perma-killing: You subverted this at least once, and that seriously undermines and devalues the perma- prefix. This will also require further consideration, but I am leaning toward interpreting attempts at recreation as violating the Ersatz rule in some way.
Perma-uncreating: I'm a bit nervous about having a set price for this given how protective everyone will probably be about possible variations in price. I'll think about it a little more.
The in-game justification for the collaboration requirement for uncreation is that removing everything about the target and uncreating it is extremely complicated and difficult to do. It's almost like the difference between an apoptotic cell and a detergent-lysed one. In the former case, it's fairly neat and orderly and keeps nasty things organized and safe. In the latter case, various dangerous components can potentially leak out, endangering nearby cells. There's probably a better analogy somewhere, but I'm not that good at coming up with them. The meta-game justification is that I don't want the richer gods to uncreate the corporeal dimension just because they got bored trivially.
