Skills

Skills are abilities that can be activated to temporarily make game progress in Clicker Heroes 2 easier or quicker. They come with a cost (either Energy or Mana), and an individual cooldown period upon use. Additionally, after each skill activation, the player has to wait one second before a next skill can be activated.

The skill cooldown period can be lowered by increasing your Haste, giving a base/haste cooldown.

That period of time can be shortened to 1s before you buy the 'Limitless Haste' node in the Skill Tree. After you bought that skill, your global cooldown time can decrease limitlessly.

Trivia

 * A preview video was released in February 2018, half a year before the game's beta version launched. In this video, a number of skills were shown to behave differently than they did at the game's release.
 * Big Clicks used to make it so your next 5 clicks deal 500% damage at the cost of only 3 energy.
 * Energize used to restore 4 energy per second for 30 seconds, with a 30 seconds cooldown period.
 * MultiClick used to be called NineClick. At the time, it did 9 clicks for 6 energy and probably wasn't upgradeable in the Skill Tree.
 * Huge Click was the only skill shown whose cost effect was still the same during the beta release.
 * In addition, all skill icons had been replaced by different ones in the beta release.
 * Prior to patch 0.06, which introduced some balance upgrades, a few skills behaved differently.
 * Clickstorm used to stay at the same speed no matter how long it had been running.
 * The dash reduction of MultiClick was introduced in this patch, as an intent to nerf builds that would infinitely rerun old worlds with a few MultiClicks for massive experience.
 * Reload used to restore everything by just 10% instead of 40%.
