Steal a Superpower: How to Level Up Cards and Unlock Their Most Powerful Ability

Quick answer

Level up the card itself. Every ability card in Steal a Superpower comes with its own set of moves, and leveling that card up is what unlocks its most powerful ability.

• You need to hold the card first — power cards are collected by opening ability packs.
• It is the card's own move set that expands when you level it, so the strongest ability belongs to that specific card.
• The starter route lists card leveling as a core early-progression step: right after fighting through the first zone and right before defeating the first boss.

What leveling up a card actually does

The upgrade attaches to the individual card rather than to your character in general. What actually grows when you level is that card's own move set, so the strongest ability you unlock belongs to the specific card you leveled, and it comes into play only through that card.

Leveling is an action you take with a card you already hold, not something that happens as a side effect of fighting. That gives the step its shape: one prerequisite — you have to actually possess the card first — and its own place in the early-game route.

Get the card first from ability packs

Power cards are collected by opening ability packs. Rip a pack open, and each card you pull grants a power — the lineup includes lightning, fire, frost, gravity, time, shadow and gold, with more beyond those. So the path to a levelable card starts at the packs: open them, collect the card whose power you want to build, and its move set becomes yours to level.

The Steal a Superpower packs guide covers the packs in more detail.

Where card leveling sits in the early game

The starter route laid out for new players lists card leveling as step four:

1. Fight through the first zone and use your powers against enemies.
2. Level up a card to unlock its most powerful ability.
3. Defeat the first boss to open the next area.

Read in order, the placement tells you when the step is meant to happen: after you are already fighting through the first zone with the powers you collected, and before you take on the first boss that opens the next area. It is a position in a sequence, not a level-number requirement — the route lists the action itself rather than naming a specific card level you must reach first.

Habits that sit alongside the leveling step

The same tips list pairs card leveling with two habits that feed the same progression:

• Place your cards on holders so they earn cash for you, even while you're fighting.
• Use upgrades, trails and auras to boost your Power, Health and speed.

Holders turn the cards you have already collected into cash income, and cash plus upgrades are how you keep pace while you fight. A leveled card with its strongest ability unlocked is the combat half of that routine; holders and stat boosts are the earning-and-stats half.

Card leveling in the full progression loop

Zooming out, card leveling is the growth step inside the route the game describes: open ability packs to collect power cards, fight through the zones with your powers, level cards up so their most powerful abilities come into play, and defeat bosses to open the next area and collect their loot. The stated end goal is beating the Dominus bosses, ending with the final boss, Dominus Empyreus — collect powers, grow stronger, and take them down. A card whose most powerful ability is unlocked is exactly the grow-stronger part of that goal, made concrete.
