We noticed some concerns related to AI taking over for players in the Battle Arena.
To answer these concerns, the AI takes over if a player has dropped out of the battle. This is normally the result of a connection issue. When that happens, the battle AI will temporarily fill in for the disconnected player.
If a player disconnects from a battle session, the AI takes over by using basic strikes, so as to not activate any cooldowns. If one of the disconnected player’s creatures is defeated, the AI will select the next available creature, starting furthest to the left. Once the player reconnects to their battle, they will regain control of their battle. The time the AI spends battling for the disconnected player is dependent on how long it takes the player to relaunch the game.
