Raid: Shadow Legends shards: summon chances and Mercy

Pick a shard to see its summon chances, the game's own description of the Mercy System and a calculator: enter how many shards in a row you have opened without a Legendary (or an Epic, or a Mythical), and it shows your chance on the next shard and how many shards are left until the guaranteed one.

All numbers are verified and match the game's drop rate window. New accounts sometimes get a faster Mercy for their first Legendary — if so, the game shows it in the same window.

How many shards have I opened?

Enter how many champions of each rarity this shard type has given you, including the ones you fed or sold. The estimate cannot see the shards opened after your last champion of the counted rarity — add them yourself. The most common rarity gives the most precise answer.

How the Mercy System works — in the game's words

The odds of summoning a Champion of a certain Rarity depends on the type of Shard. Every Champion of the same Rarity has an equal chance of being summoned, except when Targeted Champion Boosts are active. Targeted Champion Boosts increase the chances of summoning specific Champions.

The Mercy System activates after you summon a certain number of Shards without getting a Champion of a specific Rarity.

Once activated, the Mercy System increases your odds of summoning Champions of a specific Rarity with every consecutive Shard you summon of that Type. For example, after summoning 20 Void Shards without getting an Epic Champion, your chance of getting an Epic Champion from Void Shards will increase by 2% with every Shard - until you get an Epic Champion, at which point the odds will reset back to the default chances for that Rarity.

  • Your Mercy counters are tracked individually for each Type of Shard - meaning even if you Summon a Legendary Champion from a Sacred Shard, it won't affect your Mercy counter for Ancient Shards.
  • After you successfully summon either an Epic, Legendary or Mythical Champion, your Mercy counter will reset for that Rarity from that type of Shard and your chances will reset to those displayed in the Default Summoning Chances table.
  • For Ancient and Void Shards, the Mercy counters for both Epic and Legendary Champions are tracked individually. For Primal Shards, the Mercy counters for both Legendary and Mythical Champions are tracked individually. This means even if you get a Legendary Champion, it won't reset your Mercy counter for Epic Champions if you've already gone 20+ Shards without summoning an Epic.
  • The chance increases are additive, not multiplicative (meaning an increase of 2% to an 8% chance will take it to 10%).
