Fire Emblem Engage: Rewarp Duping Factory

Discovery video: • Fire Emblem Engage: Du...
Quick instructions:
Get a bunch of characters with nearly 100 EXP in a staff using class (or with Emblem Micaiah). Have them hold Rewarp and nothing else.
When safe, Engage everyone on the same turn, then end turn. If an Engage weapon moves to the first slot, move Rewarp back to the first slot.
Next turn, cast Rewarp to Level Up. The user will automatically switch to the Engage weapon. Do this for every Rewarp user.
Finally, use the Time Crystal to return to before casting Rewarp. Hey presto, everyone has 2 Rewarp staves.
The duped staves will have 1 less use than the original. However, Hortensia can trigger World Tree to retain her Rewarp use.
(Fun fact: You can reach 0 use, which looks like infinite uses, but still breaks when using it. So it effectively has 1 use.)
If you keep doing this, you can eventually overwrite the Engage weapons, but don't worry, because they are stored separately and will return after you remove the extra staves/items.
Or you can keep them stored, for example for Leif, so he doesn't use his Engage weapons. Or Tiki so you can fight with non Breath attacks (only during the enemy phase).

its sad doing this might be easier to do than randomly feeding 3* into the well for rewarp.
