I have yet to try it, but I want to try and get some maxed out gear for the next character I play as I just finished my Amara build and I was curious if you can redeem the bonuses again that scale to your level.
You get one set per character. Work on alternate account on PS4 too.
Every character should be able to claim them. They will of course be locked at whatever level you claim them on. However the Xp bonus of the shield quits working at level 10 no matter what level the shield is.
