Currently, there is no rarity type assigned to the gnomengarde grenade from the adventure Divine Contention. For this reason, it shows up on the "Common", "Magical" list when adding equipment on the digital character sheet.

I sometimes tell my players to add a common magic item to their equipment (either at character creation or as reward). Of course, the gnomengarde grenade *shouldn't* appear as a common magic item potentially dealing 8d6 fire damage and 8d6 thunder damage.... (!!!)

Nowhere in the item's text does it specify the reason why the rarity varies... Likely an errata, but should probably be changed to very rare or even Legendary, if it is a unique item link to a specific adventure. 

A player of mine just thought it was a common item as well, so this issue hasn't been resolved. Just letting you know!

I just hit level 2 with an artificer and I thought "super fireball grenade every day for an infusion? Aweso- wait, 'varies?' I'd better check this."

Please update it to not be listed with the common magic items to save DMs with less observant players.

This item is still showing as *rarity varies* yet no chart for the varying rarity. This would be great for an Artillerist I'm working on and assume it would be rare-very rare. Any fix in the works, two years later?

If the search feature could find things with the Common tag, I'd have no issues with items like this showing up with the other white magic items.

its probably a side effect of whatever automatic tools DDB uses to input the book data into the site. My guess is it looks for the tag next to an item that says the rarity. The default if it can't find it must be common.
