Summoning & Fusion Mechanics

Everything you need to know to optimize your Gems, track your pity, and fuse your way to a roster full of Mythics.

💎

Banners & The Pity System

The gacha system runs on **Gems**. It costs **100 Gems** for a single summon and **1,000 Gems** for a multi-pull (10x).

  • 30-Minute Rotations: There are typically two active banners at any one time. The units featured on these banners rotate completely every 30 minutes. Do not pull if you don't need the rate-up unit!
  • 100-Pull Pity: Every banner guarantees a Legendary unit within 100 pulls.
  • WARNING - No Shared Pity: The pity counter is **NOT** shared between the two active banners. If you do 90 pulls on Banner A, Banner B will still be at 0/100. Be careful not to split your Gems!
  • WARNING - No Mythic Pity: There is absolutely no observable pity system for Mythic units. Pulling a celestial Mythic relies entirely on unmitigated RNG or acquiring Mythic Shards via developer codes.

Fusions & Star Upgrades

Unlike many other auto-battlers, Summon Heroes has a very forgiving upgrade system for your units.

  • Universal Fodder: You DO NOT need an exact duplicate of a hero to increase its star level. You simply need another unit of the **same star rarity**.
  • Don't Auto-Sell: This is why you should never auto-sell Common or Rare units. They serve as valuable fodder to chain-fuse up to higher star levels. The fusion engine scales geometrically, requiring hundreds of base common units to achieve the absolute highest red-star tiers!
  • Fusion Crystals: You can substitute heroes entirely by using Fusion Crystals. Legendary Fusion Crystals can be acquired from codes, events, or the Nightmare Circus.

Best AFK Strategy for Gems

Running low on Gems? If you need to step away from your PC, head over to the **Training Dojo** in the main hub. Utilizing the AFK mode here will passively funnel Gems and Gold into your account while you're away. Combined with Active Codes, you'll hit your 100-pull pity fast!
