Zid (Atomic)

The All Range Atomic active ability is by far the best global AoE in the game, unleashing a devastating 50% damage burst across the whole map. It has a long cooldown (120 seconds), but that's completely justified.

The Atomic Blades passive is absolutely insane, as it deals a massive 300% damage AoE (Atomic Maelstrom) around him every 25 seconds.

As if his insane AoE capabilities weren't good enough, he also has an excellent base DPS boost in the form of Eminence Stacks, which are relatively easy to collect, making not only his base attack stronger but also all of his AoE abilities, which are based on a percentage of his base attack.

Long cooldowns, but they are justified by the sheer power of his abilities.

It takes a bit of time for his true power to come online.
