Steal a Superpower Index Guide: What It Is and How to Fill It
The Index is Steal a Superpower's collection menu. Learn how to fill its rarity entries by beating bosses, carrying packs home and opening ability packs.
The Index is Steal a Superpower's collection tracker, and the game's own description tells you why it matters: "COMPLETE THE INDEX to earn permanent rewards for every rarity you collect." Two things follow from that line. The Index fills up from ability packs — ripping packs open is how its entries get collected. And the payout is structured per rarity: every rarity you collect earns its own permanent reward, with a completed Index meaning you have collected powers of each rarity.
Quick answer
The Index is the game's collection menu. Its rarity entries are filled with the power cards you pull from ability packs, and every rarity you collect earns a permanent reward.
- A completed Index means you have collected powers of each rarity
- The hard part is rarity, not volume: the deep rows need rarer cards
- Reward contents are not spelled out in the game's description

Filling entries: the pack loop
Every Index entry traces back to an ability pack. Packs hold power cards — lightning, fire, frost, gravity, time, shadow, gold and more — and every card comes with its own set of moves, with leveling a card up unlocking its most powerful ability. Packs do not appear on their own, though: they come out of the game's core loop, and running that loop is how rarity entries actually get filled.
From boss fight to Index entry
Fight through the zone
You smash enemies with your powers, and the world breaks apart around you as you fight.
Defeat the boss
Beating a boss opens the next area.
Crack loot chests and carry packs home
The defeated boss's loot chests can be cracked open, and you carry the packs home.
Rip open ability packs
Each pack holds power cards such as lightning, fire, frost, gravity, time, shadow and gold, every one with its own set of moves.
Fill Index entries
The powers you collect from packs are what fill the Index's rarity entries, and each rarity you collect earns a permanent reward.
The cards you collect bring new moves and level toward their strongest abilities, which is what lets you handle the next area and run the loop again.
The packs guide goes deeper on the packs themselves, and the card rarities page lays out the tiers those cards fall into.
Why boss progression is the engine
Defeating bosses keeps the whole cycle supplied. Each boss you beat opens the next area, its loot chests can be cracked open, and you carry the packs home — so pushing deeper through the zones is how new cards keep flowing into your collection. The game frames its own endgame as a challenge: "Can you pull an Ancient card and beat Dominus Empyreus, the final boss?" Pulling the game's headline rarity and beating its final boss are presented together as the top of the mountain, so treat deep zone progression and Index completion as two views of the same climb.
The bosses guide and the how to unlock areas page map the route upward, and the boss loot page covers what defeated bosses leave behind.
Speeding up rare pulls with Luck Potions
The hard part of Index completion is rarity, not volume: the deep rows need rarer cards. Luck Potions raise the chance of pulling stronger or rarer superpower cards from packs, which means better moves reach your collection sooner and the finished Index comes faster. They apply to what you pull from packs — for how to get them, the potions guide is the place to look.
The free Legend Pack head start
One injection of cards is free before any of that grind: the game's announcement offers "Like and join the group for a FREE Legend Pack." A Legend Pack adds extra cards to your collection right away, so it pads the collection feeding your Index from minute one. Keep one limit in mind: which specific rarity rows those extra cards land in is not demonstrated, so treat the pack as free collection padding rather than a guaranteed step toward a particular rarity reward. The free Legend Pack page has the details, and current working codes are kept up to date on the codes page.
Reading your progress
Because each rarity you collect carries its own permanent reward, the Index pays out in stages as your collection widens — each rarity you collect earns its reward along the way. The reward contents are not spelled out in the game's description; the index rewards page covers that side. To see what is left to chase, the all superpowers catalog is the broader reference for the game's superpowers.
