I'm in the process of converting some of my player's character sheets into D&D Beyond and ran into something. The rogue has the Stone of Golorr, and it appears to me that he would have access to the entire entry of the Stone of Golorr, even the parts that are clearly meant only for the DM: "Destroying the Stone". Is there any way to limit this information?

I have the same question, specifically regarding cursed items. As of now, DndB does not have a way to hide 'spoilers' for items or things. If you're homebrewing it, you can just choose to restrict adding these things to the description.. choosing to add it at a later time, or not. 

I am still unsure what I will be doing what my players encounter said cursed items in my campaign. Also following for others' advice

Create a home brew magic item, with a similar name, and a subset of the canonical version's verbiage, and give them one of those instead.

If you're issuing the item to a player in your campaign on D&D Beyond, then homebrew is the answer!

If you head to the homebrew pages and go to create a homebrew magic item, it will give you the option to use an existing magic item as the template - select the item you want and now you have a homebrew copy of it. All you need to do is edit out the bits you don't want before awarding it to the character.

This can be very tedious. Especially with cursed items.

@stormknight As a moderator, is there any way that we can request or suggest some sort of 'spoiler warning' or hidden drop down section or something similar on cursed items or items with DM information like this?
