What can I do with Antimatter?
You can use Antimatter to summon heroes from portals inside Einstein’s Time Portal. Each type of Antimatter has its own summoning rules, such as which hero rarities are available and whether certain heroes have an increased chance to appear.
You can review all types of Antimatter at any time in your

Inventory, accessible from the bottom menu, under the Antimatter tab.
Antimatter
Regular (blue) Antimatter is the most common type in the game. It gives you a chance to summon heroes of all rarities, with a small chance of receiving a 5-star hero.
After a certain number of summons without receiving a 5-star hero, your next summon is guaranteed to be a 5-star hero. If you summon a 5-star hero before then, your pity bar will reset.
Legendary Antimatter
Legendary Antimatter guarantees either a 4-star or 5-star hero, giving you quicker access to some of the game’s most powerful heroes.
This type of Antimatter is very uncommon and is usually collected as Legendary Antimatter Pieces.

Antimatter Pieces
While playing the game, you can find Antimatter Pieces for Regular or Legendary Antimatter. Once you collect 20 Pieces, they are automatically converted into the corresponding Antimatter.
You can check how many Antimatter Pieces you have collected directly from your Inventory.
Arcane Antimatter
Arcane Antimatter guarantees a 3-star, 4-star, or 5-star hero, while offering an increased chance of obtaining exclusive seasonal heroes.
Each season features a special 4-star and 5-star hero. When you summon a hero of one of these rarities, there is an increased chance that it will be the corresponding seasonal hero. If you summon a non-seasonal hero of that rarity, the next hero you summon of the same rarity is guaranteed to be the seasonal hero. This guarantee carries over between seasons.




Allied Culture Antimatter
Allied Culture Antimatter, such as Viking Antimatter, offers an increased chance of obtaining specific heroes tied to the Allied Culture City event.
Once the current city event ends and a different Allied Culture City event begins, Antimatter from the previous Allied Culture will no longer be usable in the active portal. However, it will remain in your Inventory and become available again when that specific Allied Culture City event returns.
Special Time-Limited Antimatter
During special occasions and major events, you can earn special time-limited Antimatter with limited availability.
This Antimatter can summon event-exclusive heroes, such as Nefertiti from the Anubis’ Awakening Time Portal.
When the special portal closes, any remaining time-limited Antimatter will be used automatically. The heroes and any other rewards you receive will be added directly to your account.

If you summon a hero you already own, the duplicate will be converted into that hero’s Essence, which is used for Awakening. If the hero is already fully awakened, the duplicate will be converted into Chrono Crystals instead, which can be spent in the Chrono Shop.
