Slavery prototype
In line with the books, faiths can have a wide variety of slavery doctrines, determining who can be legally enslaved, if any.
If you've abolished slavery, you can wage an emancipation war CB against slaver targets, freeing the targeted counties under the rule of a peasant leader, who you then offer your protection as an ally.
Spymasters can Incite Rebellion in slaver counties, damaging control and county opinion - but risking discovery!

Tribal Federations
Tribes of a culture may loosely band together in a Tribal Federation, which effectively renders all members allied to each other. A variety of bonuses are available based on which culture the tribe is associated to.

Disadvantaged Duels (BETA)
To access beta content, activate the Beta Content game rule.
A beta implementation of the combat system for Dungeon Delves has been added to the dueling system.
When offering a Disadvantaged Duel, you're saying "I'll take on you and whoever you'll bring!"
Depending on your Intrigue, you may or may not be informed of the full rules before the duel starts.
Your perks, traits and artifacts determine which skill sets you get - the basic skill set is not terribly deep, but many traits and perks will interact and provide interesting synergies.
There's always another secret.

Features
Shardic Victories; A generalizing system for major endgame decisions such as restoring/dismantling the Oathpact.
Shardic Victories allow you to dedicate Roshar in its entirety to a specific Shard of Adonalsium, such as Autonomy or Endowment. If you play with the Shardic Victories game rule set to "All" then accomplishing all Shardic Victories will allow you to Restore Adonalsium.
CHALLENGE: If anyone can *legitimately* Restore Adonalsium on stupid difficulty and document it via a Youtube series or similar, then you can dictate an entire feature to me and I'll make it (Within the realms of possibility)
It is now possible to get the Awakener, Hoid, and Mistborn traits (via the Shardic Victories)
