There are a myriad of weapons of war at your disposal when you enter the battlefield in League of Legends, including the Annihilator, which allows you to destroy huge groups of Primordians in battle.

The Annihilator can be obtained after leveling up your champion, but like any other weapon in the game, you have to find it randomly. Once you get the weapon, you'll quickly realize how devastating it can be in the right circumstances.

When active, the Annihilator casts a massive AoE beam from the sky that deals massive damage to anything in its radius, but it does have a longer cooldown than most. It’s a good tradeoff for how effortless it is to destroy targets, but you’ll need to complete a specific task first to unlock this item for use.

Here's how to unlock the Annihilator in League's new Swarm mode.
