Aether Shards are a type of Crystal that you can use to upgrade Talents in Call of Duty: Mobile. Specifically, the Undead Siege zombie mode can be played either alone or with a team. However, to increase your chances of picking up Aether Shards, you will need to play matches in Hard Mode, meaning a strong team is highly recommended.

Killing zombies and beating the daily challenges often rewards you with Aether Shards and Aether Crystals, which you can then use to improve your Talents via the Lobby screen. As well as this, you can also use the Shards to improve your Turret Weapon, Turret Armor, Weapons, Toughness, and Advanced Tools.

In order to stack up Aether Shards, you will need to form a team and beat five nights of Undead Siege on Hard Mode. This can be rather difficult, so it’s best that you assemble a strong team that shares a common goal. Having a teammate with a Turret Weapon at a higher Talent level will give you the edge needed to beat the later nights.
