Wizards of the Coast has released a free PDF supplement (yes, free, as in “no cost”) to Hoard of the Dragon Queen that includes magic items, monsters and spells.
You can’t argue with the price, and it’s a nice thing to have while waiting for more when the 5th Edition Monster Manual releases September and the Dungeon Master’s Guide releases in November.
According notes in the PDF, here is the breakdown of what is from where:
- Magic Items: Dungeon Master’s Guide
- Monsters: Monster Manual
- Spells: Player’s Handbook (if not already listed in the free D&D Basic Rules PDF… in other words, if it’s in the Basic Rules, it’s not listed here)
There’s also a note that these rules are a work in progress, so don’t get upset if something changes by the time the rules in question release. There’s also a note that some (all?) of this will make it into the Basic Rules at some point.
