Are there any magic items in 5e that will cast Pass Without Trace?

I’ve been looking for a way for my Assassin Rogue 12/War Domain Cleric 2 character to be able to cast Pass Without Trace, so they can more easily not abandon the party and still get surprise. Getting that surprise round is the goal, so if you have another way we can do it, that’d be great. Our party does not have a druid or thief rogue, so unfortunately we cannot use the Staff of the Woodlands, which would otherwise be perfect because, well:

You can also use an action to cast the Pass without Trace spell from the staff without using any Charges.

Anyways, Does anyone know of a similar magic item that will allow us to cast pass without trace? Or an alternative way to gain surprise on our enemies other than stealthing into each room?
