Earthquake

Earthquake is a 3 Elixir ground-only spell that covers a 3.5-tile radius, hitting immediately and then twice more once per second for a total of three pulses over 3 seconds, while slowing every ground troop and building it touches by 50% movement speed for that whole time. It deals only moderate damage to troops but noticeably heavier damage to buildings, making it a go-to tool for tearing down defensive structures like Tesla and Cannon rather than a big troop-killer or tower-finisher.

• Earthquake is a 3 Elixir spell that covers a 3.5-tile radius and hits the instant it lands, then pulses two more times, once per second, for a total of three hits over 3 seconds. Everything ground-based caught in the blast, troops and buildings alike, also has its movement speed cut by 50% for the full 3 seconds. At tournament standard (level 11), each pulse deals 84 damage to troops (252 total) but a much heavier 287 damage to buildings (861 total), which is why Earthquake is one of the best spells in the game for demolishing defensive structures like Tesla, Cannon, and Inferno Tower rather than fighting troops directly.

• Against Crown Towers specifically, Earthquake hits noticeably softer than it does against buildings: at tournament standard it now deals 49 damage per pulse for 147 total across its three hits — down from a previous 159 total, after Supercell cut Earthquake's Crown Tower damage by 8% in a June 2026 update that reduced tower chip damage from nearly every spell in the game at once, aimed at discouraging players from leaning on pure spell-cycle chip damage instead of pushing with troops.

• Earthquake has been part of Clash Royale since 15 April 2019.

• Earthquake didn't always work the way it does now. Before June 2020 it also slowed enemies' attack speed on top of their movement speed, and that combination made it devastating alongside fast-hitting troops like Hog Rider, since defenders simply couldn't swing back at full speed. Supercell removed the attack-speed slow entirely and boosted the movement-speed slow from 35% to 50% instead, refocusing the spell on punishing troops caught out of position rather than shutting down well-placed defenders.

• Earthquake has a quirky interaction with Tesla: it can damage the tower even while it's retracted underground and untargetable, a specific fix Supercell added so the spell wouldn't feel inconsistent with other area spells like Freeze, which could already reach a hidden Tesla.

• In May 2020, Earthquake's overall damage was buffed by 11%, but its bonus damage multiplier against buildings was scaled back from 300% to 200% of its troop damage - a trade that made it hit slightly harder across the board while easing off just how devastating it was specifically against defensive buildings.

• Earthquake only ever targets the ground. Its blast radius still visually covers any flying troops standing over it, but Minions, Baby Dragon, Balloon, Mega Minion, and every other air unit take zero damage and get no movement slow from it whatsoever.
