Please note that there are 3 possible chests a player could get.

1.The Participation Chest for the node - not guaranteed, one random player who joined the node (never the leader) gets this if the node is defeated. This has regular artifact tokens in it in case of both Uncommons and Rares.

2.The Leader Chest - the person who spent the directives and started the node always gets this if the node is defeated. This has premium artifact tokens in it in case of an Uncommon Formation Armada and complex nanotech in case of Rare Formation Armadas.

3. The Artifact Chest - if all 3 nodes are defeated, every player who participated is meant to get exactly one of this chest in addition to whatever chests they got from the nodes. This has the artifact shards in it for both Uncommons and Rares.

Since you can send ships to multiple nodes, your possible rewards would be:

→ 0 - 3 Participation chests, depending how many nodes you joined and whether you were the person who got the chest or not. So if you joined one node, you could get 0 or 1 of this chest, if you joined 2 nodes, you could get 0, 1, or 2 of this chest, and if you joined all 3 nodes, you could get 0, 1, 2, or 3 of this chest.

→ 1 Leader chest if you led any of the nodes, otherwise 0 of these. You cannot lead more than one node at the same time so you shouldn't be able to get more than 1 of these per Formation Armada

1 Artifact chest - if all three nodes are defeated, you should always get exactly 1 of this.

Breakdown per type:

Uncommons

→ node participation chests contain artifact tokens

→ node leaders chests contain artifact tokens and premium artifact tokens

→ win chests for defeating all 3 nodes

Rares

→ node participation chests contain complex nanotech and artifact tokens

→ node leaders chests contain complex nanotech

→ win chests for defeating all 3 nodes

We hope this information helps - good luck out there, Commander!
