Empires & Puzzles: Match-3 RPG Costume Summon Pull Guide

In Empires & Puzzles: Match-3 RPG, spend your earned Costume Keys in the Costume Chamber whenever the event appears. Every summon from this portal grants both the costume and an additional copy of the base hero. Using earned keys provides reliable roster upgrades for tournament and War teams without requiring premium gems.

Spending Costume Keys vs. Gems

Costume Keys are the dedicated currency for the Costume Chamber, requiring five keys per pull. Clear every stage of the recurring Costume Chamber quest to collect keys without spending gems.

Summon Currency	Cost Per Pull	Resource Priority	Usage Recommendation
Costume Keys	5 Keys	Primary	Spend as soon as earned during the event.
Single Gem Pull	Gems	Low	Avoid; save gems for portals with non-classic heroes.
Multi-Gem Pull	Gems (Bulk)	Situational	Use only if your roster severely lacks core 4-star heroes.

Because the Costume Chamber draws from classic heroes whose baseline versions are obtainable from regular training camps, spending gems here carries a steep opportunity cost. Save your gems for portals offering event-exclusive hero families, and rely on quest-earned keys to fund your Costume Chamber pulls.

Evaluating 3-Star and 4-Star Pulls

Most small-batch summons produce 3-star and 4-star heroes. These outcomes hold substantial value for Rare and Epic Raid Tournaments, Challenge Events, and Alliance War depth.

When you pull a new costume, check two specific mechanics:

Skill Swaps: Costumes frequently alter a hero's combat role. A direct damage dealer may become a support specialist that cleanses status ailments, dispels enemy buffs, or boosts defense.
Class Alignment: A costume changes the hero's class tree. This allows you to bypass class restrictions in trial quests and invest surplus emblems that your primary roster does not need.

Focus leveling resources on 4-star utility costumes first to expand your Alliance War teams, followed by 3-star specialists for tournament restrictions.

Unlocking the Costume Bonus

Leveling a costume grants a permanent passive stat bonus to the hero. This bonus applies even when you equip and field the original base version of the hero in battle.

Stat Boosts: Unlocking the full costume bonus increases attack, defense, maximum health, and mana generation.
Mana Breakpoints: The passive mana generation boost can reduce the total number of shield matches needed to charge a hero's special skill, improving average-speed heroes significantly.
Reduced Upgrade Costs: Leveling a costume requires substantially less food and fewer feeder heroes than leveling a base card. Furthermore, it requires no additional rare ascension materials if the base hero is already fully ascended.

Prioritize maxing out costumes for heroes you actively deploy in Raids and Alliance Wars to secure the maximum passive stat ceiling.

Managing Duplicate Heroes and Costumes

When you pull a duplicate costume, you also receive an extra copy of the base hero card. Manage these extra cards based on their star tier:

3-Star Duplicates: Keep one fully leveled copy of each costume. Extra base copies can be used as high-experience training feeders for your other heroes.
4-Star and 5-Star Duplicates: Retain second copies of key support heroes—especially defense debuffers and cleansers—to bolster your depth across six Alliance War attacks.
Costume Feeding: Unwanted duplicate costumes provide accelerated experience when fed to costumes of the same element. Always complete your primary copy's leveling before feeding off duplicate versions.
