When you reforge a weapon from 20 back to 1, does that mean you can no longer fight level 20 behemoths with that weapon and have to go back to the first few shattered islands?

after your first reforge, you can unlock the slayer path ability to "bank xp".
so you can earn xp while at the high earning Level 20; and put it into the "bank" (per weapon type). a full bank effectively takes to straight to Level 6 after reforging.

(I always get max bank before reforging)

To add to this, you can also complete bounties and not collect them until after reforge to get an extra boost.
