How to Prep for Soul Exchange in Empires & Puzzles: Match-3 RPG

To reach a target tier in the Soul Exchange event in Empires & Puzzles: Match-3 RPG, cash in your accumulated Training Camp level 20 (TC20) queue, evaluate your duplicate 5-star heroes, and clear the resulting roster bottleneck before making your trade. Soul Exchange trades require sacrificing 10, 15, or 20 legendary heroes for a single selected hero, and every trade is permanent.

Cashing Out Training Camp 20 Queues

Training Camp 20 serves as the primary free-to-play source for Soul Exchange fodder, yielding classic 3-star, 4-star, and 5-star heroes with an approximate 5% legendary drop rate. Claiming completions right before trading reveals your exact legendary count so you know which tier you can afford.

Collecting a large batch of TC20 completions—such as 40 or more saved trainings—immediately dumps dozens of heroes, thousands of recruits, and millions of food into your base. Prepare resource sinks before tapping the camp so your inventory does not lock your progression.

Evaluating Fodder Across Exchange Tiers

Soul Exchange features three fixed exchange brackets. Categorize your 5-star bench into protected roster anchors and disposable duplicates before opening the event interface.

Exchange Tier	Target Caliber	Recommended Fodder
Tier 1 (10 Heroes)	Solid niche heroes, older Heroes of the Month, support specialists	Uncostumed Season 1 duplicates, bench warmers with zero ascension materials invested
Tier 2 (15 Heroes)	High-tier war specialists, potent mana controllers	Triple duplicates, outdated event legendaries superseded by current stats
Tier 3 (20 Heroes)	High-impact anchors, top-tier taunt units, primary dispellers	Quadruple TC20 copies, non-costumed base duplicates, redundant unleveled copies

Protect unique 5-star heroes even if they currently sit at level 1. Broad roster depth remains essential for restricted modes such as War of the Three Kingdoms, Tavern of Legends, and Mythic Titans. Prioritize feeding duplicate Season 1 heroes, duplicate Season 2 or Season 3 copies that lack secondary costume bonuses, and redundant summons that have remained unused.

Managing Roster Space and Resource Overflow

Claiming dozens of heroes at once pushes your roster over its capacity limit, preventing you from starting map stages or raids until your hero count drops below maximum.

Follow this sequence to resolve the bottleneck:

Favorite every 5-star hero you plan to keep to prevent accidental loss.
Unlock only the specific duplicate legendaries designated for the exchange trade.
Feed incoming 3-star and 4-star heroes directly into a priority leveling project, matching element colors to maximize special skill level-up odds.
Channel surplus food and recruits immediately back into TC20 or Training Camp 11 (TC11) to avoid wasting resources over your storage caps.
Execute your Soul Exchange trade, which instantly removes 10, 15, or 20 heroes from your inventory and restores normal account functions.

Handling Shortfalls with Gem Summons

If claiming your TC20 queue leaves you one or two heroes short of your target tier, targeted gem summons on active event portals can close the gap. This approach offers a chance to pull a featured hero directly or obtain the final duplicate needed for the trade.

Do not rely on portal odds to force a trade if you lack adequate gem reserves. If bonus summons fail to produce the required 5-star heroes, drop down to the 15-hero or 10-hero tier rather than sacrificing unique, irreplaceable heroes to force a 20-hero claim.

Maintaining the Passive Feeder Cycle

As soon as a Soul Exchange concludes, restart the accumulation process for future rotations:

Keep at least one Training Camp running TC20 continuously in the background.
Store duplicate 5-star summons from seasonal events, Black Friday portals, and Hero Academy safely in your roster.
Leave completed TC20 sessions unclaimed until the next exchange date to prevent day-to-day roster clutter.
