2.Ossomer is fighting with the wrong weapon. The sword was nowhere to be seen on the previous page.
And yet he was carrying it in previous panels. Bk2 Page 46 shows it clearly whole he was negotiating. If he had it before he was restore, he likely had it after he was restored. Its not shown on the previous page, but then you don't have a view of where its sheathed. At the same time, on Page 72 - the next time we get a clear view of that side of him - its not there.
Its unclear what the Dittomancer was doing, but the fact this Ossomer has a sword is simply reverting to the original model; he should have a sword. If there is any mistake, it would appear to be on Page 72 when the sword isn't drawn. There are several pages where the hilt would be expected to be but the angles and small gaps through which the sword would be seen would probably justify not drawing it.
And, as people said, Dittomancy isn't Foolamancy. We'd see two Ossomers in the air.
What we have is a rush that has deprived Jetstone of a powerful warlord and placed 5 Archons right next to the Jetstone king.
3.Slately's laser scepter is missing. Lloyd isn't familiar with it. (and possibly dupes can't use ranged attacks, or need more Juice to use Specials, or can't use Specials) His jetpack is there, but the king would FALL if it weren't. It's a necessary feature.
If Dittomancy requires the Jetpack, it requires the wand.
