RAID: Shadow Legends 2x Ancient Shard and 15x Event Guide

To maximize summoning value in RAID: Shadow Legends, save your Ancient Shards until a 2x drop rate event occurs—preferably one overlapping with a 15x targeted champion multiplier—and check your current Mercy System progress before spending your inventory.

How 2x Drop Rates and 15x Multipliers Function

Understanding the math behind summoning windows prevents wasted resources:

2x Drop Rate Events: During a 2x Ancient Shard event, the baseline chance to pull a Legendary champion doubles from 0.5% to 1.0%. This period provides the highest general account return per shard spent.
15x Multipliers: A 15x multiplier does not raise the baseline Legendary drop rate. Instead, when a Legendary champion drops, the system applies a 15x weight to the featured unit (such as Scarecrow).
Overlapping Events: When a 2x boost and a 15x boost run simultaneously, you receive both the 1.0% Legendary drop rate and the increased weighting for the featured champion.

Event Type	Baseline Legendary Rate	Purpose	Best Used By
Standard (No Event)	0.5%	Saver / Emergency	Avoid pulling
2x Boost Only	1.0%	General Roster Expansion	Early to Mid-Game Players
15x Boost Only	0.5%	Targeted Champion Hunt	End-Game / High Resource Players
Combined 2x + 15x	1.0%	Target Hunt with Boosted Base Rates	All Player Progression Levels

Managing Mercy Counts and Event Milestones

The Mercy System acts as protection against long runs of poor luck. After opening a set threshold of Ancient Shards without receiving a Legendary unit, your pull chance increases incrementally until a Legendary champion is guaranteed.

To align your account strategy before pulling:

Count Your History: Track the exact number of Ancient Shards opened since your last Legendary pull to know how close you are to your Mercy threshold.
Review Milestone Rewards: Inspect active summoning event tracks to verify whether milestone tiers grant valuable secondary items like energy, silver, or additional shards.
Set a Stopping Point: Decide on a spending limit based on your total shard count. If you are far from Mercy and cannot complete an event milestone, holding shards for future fusions or Titan events is often more beneficial.

Resource Support and Creator Codes

Sustaining shard inventories requires efficient energy and silver management. Players can redeem creator promotional codes—such as creator code KRUYSEN—in the game's code entry menu to receive additional in-game supplies like energy or silver. Utilizing these extra resources to farm dungeons allows you to gather baseline materials and secondary rewards without depleting your core reserves.
