The revamped Growth Plan in Idle Heroes gives free-to-play accounts direct access to late-game upgrade materials, including Sublimation Essence chests, Cores of Origin, and Stellar Shards. You do not need to spend gems to unlock the base track; rewards unlock automatically as your account meets standard level, Campaign, Tower of Oblivion, and Void milestones.

To maximize the plan's value, focus your daily routines on rushing your first E5 carry hero and pushing Campaign stages as soon as level caps lift.

Key Free-to-Play Rewards

Earlier iterations of the Growth Plan focused on basic summon currency, low-tier gear, and fixed hero copies. The updated system replaces those static drops with dynamic chests and endgame progression items designed to support Transcendence heroes and Tree of Origin levels:

  • Sublimation Essence Selection Chests: Provide the materials needed to evolve active and passive hero skills, bypassing long event hoarding cycles.
  • Cores of Origin: Supply core shards and chests to activate hero core abilities before reaching late Void Campaign farming stages.
  • Stellar Shards and Spiritual Essence: Deliver direct materials for Tree of Origin investment, avoiding the progression penalty of converting Void Spheres into Crystals of Transcendence.
  • Event and Hero Chests: Award 5-star hero selection chests, Prophet Orbs, and Heroic Summon Scrolls to help you clear recurring weekly and monthly event tiers.

Milestone Objectives and Progression Path

Growth Plan tiers unlock progressively as you clear account thresholds. To clear tiers without stalling, keep your primary E5 hero building process active and maintain daily stamina usage in Void modes.

Progression StageRequired MilestonesPrimary Reward Yield
Early Account (Levels 1–100)Normal Campaign clears and daily quest completion5-Star Hero Selection Chests, Basic Summons, Gems
Mid-Game PushTower of Oblivion clears and first E5 hero completionArtifact Selection Chests, Prophet Orbs, Stellar Shards
Endgame & VoidRealm's Gate depth and Void Campaign clearsSublimation Chests, Core of Origin Shards, Spiritual Essence

Clear normal Campaign stages immediately whenever level restrictions lift. Leaving cleared stages unattempted stalls your access to higher Growth Plan tiers and delays the materials required to overcome late-game combat walls.

Free Track vs. Paid Growth Track

The free progression track provides enough materials to develop a functional mid-game Transcendence hero. A paid track is also available, functioning as a high-density resource purchase for spending accounts.

Free-to-play accounts do not need the paid tier to remain functional. However, for accounts that occasionally spend on monthly cards or weekly packs, the paid Growth Plan offers higher resource density per dollar due to its heavy focus on Sublimation and Core materials.

How to Allocate Growth Plan Rewards

Distributing high-tier rewards across multiple heroes will dilute your combat power. Funnel all Growth Plan materials into a single primary carry hero until they reach full operational capacity.

  1. Save Sublimation chests for your primary Transcendence carry. Do not open or consume Sublimation chests until you have unlocked your primary carry (such as Lord of Fear Aspen or Sword Flash Xia). Upgrade their active skill node first before investing in secondary passives.
  2. Consolidate Core of Origin shards. Keep all core fragments directed toward a single hero to unlock a complete core skill rather than splitting fragments across candidate heroes.
  3. Choose Stellar Shards over Crystals of Transcendence. When acquiring spheres or allocation chests through milestone tracks, consistently prioritize Stellar Shards to ensure your carry reaches the required Tree of Origin levels.
