In 2017 Clash of Clans has begun hosting regular in-game events where you can without much of a stretch get a considerable measure of extra resources, XP and Gems.
On this page, I will provide you with about the current and future events and offer you help to get more out of these events. A number of them only provide XP and Gems, but you will get much more out of it with discounted troops along with the right strategy.
Clash of Clans Earthquake Spell Event:
The Earthquake Event reduces the cost to train a Earthquake spell dramatically and you will also be able to gain some Gems and extra XP when completing 3 attacks while using at least 12 Earthquake spell. Earthquake is a perfect spell, you can use in almost all compositions and they fit very well, so a lot of you guys will be happy about the discount for the spell.
However, using 12 Earthquake in just a 3 composition is a lot, most compositions that use Earthquake for funneling take Jump spell. The reason is they will be behind the tanks and deal enough damage, so bringing more is not helping at all.
If you want to complete the reward (I know some of you want), you should use a Giant, Healer, Wizard lineup with Valks/Bowlers in the Clan Castle.
