Idle Heroes Event Season Hoarding Guide: When to Save and Skip

To maximize account progression during the major event season in Idle Heroes, stop spending high-value currencies on standard weekly rotations and hoard them for major holiday milestones. Routine event cycles offer standard hero copies and basic fodder, while major seasonal events—such as Thanksgiving, Black Friday, Christmas, and New Year—layer special event currencies, milestone tracks, and exchange shops on top of baseline loops. Spending your hoard during these celebrations lets you double-dip on rewards, securing premium account-level materials like Sublimation Essence and Core of Origin shards.

Event Spending Comparison

Use this breakdown to determine whether an active event justifies spending your stockpile:

Event Type	Typical Extra Rewards	Spending Strategy
Routine Weekly Loop	Basic hero copies, standard feathers, minor fodder	Skip to protect resource stockpiles
Minor Themed Week	Modest event currency, selective artifact chests	Spend only if top milestone thresholds are guaranteed
Major Seasonal Event (Black Friday, Christmas, New Year)	Sublimation Chests, Core of Origin shards, artifacts, CSG rebates	Go all-in to clear full milestone tiers

Currencies to Stockpile and Minimum Targets

Reaching the highest reward brackets in seasonal events requires complete event loops rather than fragmented reserves. Focus your hoarding on four primary currencies:

Heroic Summon Scrolls (HS): Save 1,500 to 2,000 scrolls. Winter events, particularly Christmas and New Year, tie their primary reward tracks to multiple full summon loops.
Prophet Orbs (PO): Maintain a stock of 160 to 320 orbs. These typically feature as primary currencies in late-autumn events like Thanksgiving or Black Friday.
Gems: Keep an emergency liquid balance of 30,000 to 50,000 Gems. You will need these to buy limited event chests, purchase daily discounted items, and acquire extra event attempts.
Contract Starry Gems (CSG) and Awakening Gale Materials: Reserve your soul awakenings for events that feature an awakening gala track, which grants premium reward chests at specific point thresholds.

How to Identify and Skip Bait Weeks

Intermediate weeks often introduce new heroes, standalone summon incentives, or discounted artifact packs directly before major holidays. Spending partially during these weeks drains your accounts right before higher-value reward shops go live.

Apply these rules before committing resources to any non-holiday rotation:

Enforce the Complete Loop Rule: Never spend a partial loop. If you cannot reach a milestone that offers an immediate, permanent boost, do not spend any scrolls or orbs.
Evaluate Reward Ceilings: If completing the weekly track does not offer a path to a Sublimation Chest, Core of Origin, or essential artifact, save your stock.
Delay Summoning New Heroes: Unless a newly released hero immediately defines the meta for Void Campaign or bossing, skip their release banner. You can obtain copies later through regular selection chests and seasonal event exchanges.

Event Exchange Shop Priority

When major event exchange shops open, allocate your event tokens according to long-term power scaling:

Sublimation Essence Chests: First priority. Unlocking active and passive skill sublimations is necessary to scale damage and survivability on primary carries like Lord of Fear Aspen or Doom Terminator Vulcan.
Core of Origin Shards: Second priority. Required to assemble noble cores and unlock domain skills in Void Campaign.
Mysterious Artifact Selection Chests: Situational priority. Target these if your squad still lacks baseline sets of Melodic Strings, Demon Bells, or Ruyi Scepters. Once your core sets are complete, divert currency to Sublimations and Cores.
Hero Selection Chests and Stellar Shards: Spend leftover, lower-tier currency here. Never sacrifice Core or Sublimation milestones for standard hero copies.

Weekly Maintenance Checklist

Maintain your account efficiency during saving periods without consuming core event currencies:

Buy Daily Market Essentials: Purchase discounted Heroic Summon Scrolls and Core of Transcendence pieces with excess Gold and Gems while staying above your 30,000 to 50,000 Gem threshold.
Lock High-Tier Tavern Quests: Complete and hold 6-star and 7-star tavern quests in your log to finish monthly tavern resets instantly without burning Gems on rerolls during event weeks.
Hold Bag Inventory: Keep hero shards in your bag until an event actively rewards Heroic Miracle milestones or awakening gala points to avoid running out of hero slots.
Wait for Event Breakdowns: Do not spend resources on the first day of an event. Wait for community calculations to confirm the exact currency costs needed to reach each milestone tier.
