It's not about the doubles thing, it's like... I had a pocket spa with me, before here, and it just didn't show up. Whatever you did to the umbra staff must have some kinda pocket dimension, cause otherwise Kravtiz would've picked it straight away, as something undead.

[And Kravtiz suspected that something was off, but he looked at the umbra staff and passed over it. If Lup was just straight up possessing it, Taako thinks that would've gone differently.

So - pocket dimension.]
