Promotion Battle

The Promotion Battle is one of the the PvP aspects of Chain Strike. This is where players place defenses for other players to battle against. There are two possible ways to win in promotion battles; killing the other player's Nexus, or killing all the guardians on the other side. The player that wins gains Victory Points and Glory Points.

Victory Points
Victory points determine a player's ranking at the end of a season, which is every two weeks. Players gain rewards based on how well they do every season. There are multiple ranks that can be achieved;

Glory Points
Glory points are a type of currency in Chain Strike, and are spent in the glory shop. The shop can be accessed from the Promotion battle screen or the Special Shop option in the menu. Rewards are; The best investment for glory points are the skill books. After spending the 200 glory points, if there is extra, use it for Nexus buffs.

Nexus
The nexus is a building in the promotion battles. Destroying a nexus is an instant victory. Thus, there is a tactic in Promotion battles called Nexus Sniping (see below). Clicking on the nexus button in the promotion battle screen will take you to two panels. The first one is labeled stats. Here, you can upgrade the nexus, in order to level it up and make it more resistant to attempts to destroy it.

The other tab is called Nexus Buff. Here, you can buy different buffs that will apply to all champions of the same direction, in all content, permanently. This is probably the best use of Glory points, after buying skill books.
