Idle Slayer Wiki

Ultra Ascension is unlocked through the Ascension Tree for 2,000,000 Slayer Points. Ultra-Ascending will reset way more than a normal Ascension, but also grant something way stronger in return: Ultra Slayer Points. These can be spent on Stones of Time.

Furthermore new Ascension Upgrades will become available on the Ascension Tree. Check out this page for advice on when to ultra-ascend.

The amount of USP you gain is based on your Lifetime Slayer Points (total SP + unclaimed SP). Ascending is not necessary before Ultra Ascension.

The amount of SP you need for a USP is calculated using , where x is the sum of your claimed and unclaimed USP.

You need to earn at least 1 Ultra Slayer Point in order to Ultra Ascend unless you have purchased the Divinity, Ultra Prestige.

What happens when I Ultra Ascend?[]

  • You gain USP according to the formula described above
  • You gain access to new Ascension Upgrades
  • You lose all Coins and Coin Upgrades
  • You lose all Slayer Points and Ascension Upgrades
  • You lose all Quests and Quest progress
  • You lose all Minion levels and Mission progress (Divinity Points from this are properly credited.)
  • You go back to Hills
  • You lose all progress to the next unclaimed USP
