Here you can find the basic rules and concepts, you as a player should be aware of.
My Army
You should create an army - it is called your Order of Battle.
Best tool for this is this spreadsheet.
It is just like starting a new Crusade Army but except for having ony 1000 points, you start with 2000
You start with 5 RP as normal and can use them straight away on Renowned Heroes or Increase Supply Limit (note that the effect is stronger if you control certain warzones) for example.
Updating your army and playing Crusade
Be aware of the new Requisition options which replace the old ones. Most importantly, you can't just take away a unit from your roster.
We are not playing with Agendas
All updates to your Order of Battle should be done right after the battle with your opponent as witness (out of action rolls, scars, battle honors)
Games
There are three main types of games
Story Battles - only a few of them will open each round. You should play it at least once but most likely not every round.
Warzone Battles - there will be quite a few of them open every round. If you do not play a Story Battle, you should be ready to play a warzone battle
Skirmish Battles - If one game is not enough or your team really needs to reinforce somewhere, you can play any number of these battles. The bonus they give you in case of victory is 1/2 of a Warzone battle
Communication
Use discord. Talk to your team. Discuss which army will work best with which scenario and offer insight into opposing armies after you play them.
