Campaign Content Sharing and You – D&D Beyond https://dndbeyond.zendesk.com/hc/en-us/articles/115011257067-Campaign-Content-Sharing-and-You

"We originally announced that a DM has to unlock the content in order to share, but that is no longer the case - anyone in that campaign can unlock content and share it with the other people in that campaign as long as one person (doesn't have to be the DM) has a Master Tier subscription and has used it to toggle content sharing on for that campaign."

Tool Tips

D&D Beyond offers the ability to link certain aspects on the forum in mouse-over triggered tooltips, such as magic items, monsters or combat actions - examples being Adult Black Dragon and dash. To create tooltips in this way as these, use the appropriate [tag][/tag] around the desired subject.

Example: [ magicitem]sunblade[/ magicitem]  (Without spaces within the [ ] brackets.)

Use the following within the [ ][/ ] bracket system:

action - an action taken in combat - e.g. dodge, search and ready condition - a condition afflicted upon a creature - e.g. restrained, poisoned and prone item - a mundane item - e.g. torch, trident and backpack magicItem - a magical item - e.g. Bag of Holding, Dust of Disappearance and Demon Armor monster - a creature you can encounter - e.g. Banshee, Bandit and Unicorn sense - a type of extra sense, whether magical or natural - e.g. darkvision, tremorsense and truesight skill - this is used for professions - e.g. Persuasion, Stealth spell - a magical spell - e.g. Mage Hand, Magic Missile and Abi-Dalzim’s Horrid Wilting wprop - a property of a weapon - e.g. finesse, versatile and heavy

You can simulate dice rolls too with the [ roll] tag, but the workings of it are more complex. You can find the thread here detailing its use.
