FAQ

Are the adventures from the Embers of the Last War campaign or the Forgotten Relics adventure from Eberron: Rising from the Last War legal adventures to play in the Oracle of War campaign?
No. The only adventure that are currently legal in the Oracle of War campaign are the Core Storyline adventures (with the code EB) and the Eberron EPIC adventures (with the code EB-EP). If any other adventures become legal for the campaign, the adventure will say so specifically, or it will be announced and noted in the campaign documentation.
What rules sources are legal for the Oracle of War campaign?
Currently, the Player's Handbook (or Basic Rules) and Eberron: Rising from the Last War are the two legal rules sources. Other resources may be opened by campaign documentation such as Adventure Records or special event certs.

What about Wayfinder’s Guide to Eberron?
Wayfinder's Guide to Eberron is not a legal source, except in the case where the content of that source matches Eberron: Rising from the Last War exactly.
The artificer spell list contains spells from Xanathar’s Guide to Everything. Are those legal?
Yes. Artificers can use those spells. Other classes, however, do not have access to those spells or any other content from Xanathar's Guide to Everything without further documentation.
Do artificer infusions count against the magic item limit for a character?
The magic items created through an artificer's infuse item ability do not count against the magic item ownership limits set forth by the campaign. However, due to the episodic nature of the Oracle of War campaign, any items infused by an artificer lose their infusion at the end of an adventure.
The artificer character can, at the start of the next adventure, infuse items again. If the exact same characters and same DM play several adventures in a row, then the DM can choose to waive this restriction and allow the items to remain infused between adventures.
How do greater aberrant powers from an aberrant dragonmark work?
Players with an aberrant dragonmark do not roll to see if they gain an epic boon. Potential greater aberrant powers will be managed through Adventure Records or other campaign documentation.
Can I play an orc, bugbear, goblin, or hobgoblin?
Yes. Eberron: Rising from the Last War talks about the heritage of these races in Eberron. Use the statistics and traits from this book instead of other sources.
