I still think that the comic has pretty well established that units aren't arbitrarily stripped of their possessions by their rulers simply because those rulers think that some other unit would be a better owner. Saline certainly didn't order Stanley to hand his 'hammer over to the current CWL or some higher level warlord, Stanley hasn't seen if anyone else could attune to the 'pliers, etc. I don't recall a single example of any ruler ordering some unit to hand their magic item over to another unit. Jetstone tried all princes to see if they could attune. That makes sense. And if some Jetstone prince could attune, I don't doubt that Slately would have had Ansom hand them over. But we still never saw that happen, and it suggests that the 'pliers were held as a sort of 'side' item that went to whomever could get some good use out of them. Or perhaps the use of the 'pliers was an heir prerogative.
Why did the GK armory hold so many magic items for Parson to equip, rather than having those items distributed to the units in the field? Does anyone doubt that Sylvia wouldn't be better off with a staff of magic resistance? Or some other warlord better off with whatever those claws do? Or the cloak? Or anything else? They don't do the side much good just sitting in the armory... It's a bit baffling. But still, personal property seems to be respected by rulers and other superiors who could conceivably order the owners to hand the items off to better suited users.
I think some of these are somewhat explained *if* we were to assume certain rules. The idea makes me think of playin RotTK. Where taking an item from a general reduces loyalty. You wouldn't want to hand all your items out incase you needed them at some point and you wouldn't take them willy nilly else loyalty would suffer. If it was enough of a penalty it'd make sense.
Also on the Arken Tools, I personally think that Stanley is a bad example. "I could take an attuned tool and piss off the attuned party to give it to someone who might not attune." And anyone not attuned with the slightest duty would be okay giving them to someone who could attune. Since the power swings they give are insane.
Though I think with the pliers Jetstone made a mistake because of the royalty mandate, while they grant decrypted I think any caster might get a different super effect. Hammer - Warlord, Pliers - Caster, Dish - Ruler, whatever else. (The tools could be REALLY specific or they could change slightly depending on who attunes, like the hammer taming megalogwiffons. Either way at LEAST put an un attuned tool in the hands of everyone with any kind of loyalty. =/
