What Is Mastery XP in Marvel Snap?
Character Mastery is a per-card progression system added to Marvel Snap in February 2025. Each of your cards has its own mastery track from level 1 to 30, and leveling up unlocks exclusive cosmetic finishes, flares, and other rewards for that specific card. Mastery is independent of card rarity upgrades, so your Infinity Splits and your mastery track progress as separate systems with different rewards.
How to Earn Mastery XP
There are two main sources of Mastery XP for a card. Owning variants of that card grants XP based on the variant's rarity: Rare variants give 25 XP, Super Rare give 75 XP, Spotlight variants give 125 XP, and Ultimate variants give 250 XP. Infinity Splitting the card grants 15 XP per split, making repeated splits a reliable way to grind mastery over time. Between variant ownership and splits, most active players hit meaningful milestones on the cards they use frequently. The early levels come quickly (level 2 requires just 5 XP, level 10 needs 150 XP), but later levels demand significantly more. Going from level 20 to 30 costs 650 XP, which is exactly half the total 1,300 XP needed for max level.
Mastery Rewards
Leveling up unlocks cosmetic rewards exclusive to that specific card. Milestone levels award specific finishes and flares: level 10 unlocks the Refraction finish, level 15 unlocks the Cosmic Flare, level 20 unlocks the Metallic Gold Finish, level 25 unlocks the Fire Finish, and level 30 unlocks a Character Reaction Set and Gold Diamond Flare. Between milestones, Mastery Caches award randomized cosmetic effects from a tiered reward pool: Tier 1 caches at levels 2 through 9, Tier 2 caches at levels 11 through 14 and 16 through 19, and Tier 3 caches at levels 21 through 24 and 26 through 29. These mastery-exclusive cosmetics cannot be obtained through regular Infinity Splits, making high mastery cards visually distinctive.
Mastery and Split Probability
Your mastery level also influences Infinity Split probabilities. Higher mastery unlocks additional cosmetic effects in the standard split roll pool, which changes the distribution of what you can receive. At mastery level 1, the pool is smaller and certain rare finishes have higher relative odds. By level 30, the full pool is available, making any individual outcome less likely but giving you access to cosmetics that lower-level players cannot roll at all. The premium combo roll (Ink or Gold finish plus Krackle flare) stays at a flat 10% regardless of mastery level.
Mastery Tracking on SnapComplete
SnapComplete displays your mastery level and XP progress for every card you own. Each card's detail view shows your current level, exact XP earned, XP remaining to the next level, and your percentile ranking among all tracked players for that card. The Splits page supports sorting by Mastery Level and Mastery Rank so you can quickly find your highest-level cards or spot cards close to a milestone unlock. The Card Leaderboards let you compare mastery rankings card by card against the full community. Premium members can see exactly where they stand relative to other tracked players and chase the top spots on individual card mastery leaderboards.
What Is the XP Curve for Each Level?
Mastery XP requirements ramp up as you progress. The early levels are cheap, basically freebies for picking up a single Rare variant or two. The mid-range (levels 10 to 20) starts demanding real investment, and the final stretch to level 30 is a grind reserved for your favorite cards.
| Level Range | XP Required | Cumulative XP |
|---|---|---|
| 1 to 2 | 5 | 5 |
| 2 to 5 | 5-15 each | 35 |
| 5 to 10 | 15-30 each | 150 |
| 10 to 15 | 35-50 each | 375 |
| 15 to 20 | 50-65 each | 650 |
| 20 to 25 | 65 each | 975 |
| 25 to 30 | 65 each | 1,300 |
The first 10 levels account for about 12% of the total XP needed. The last 10 levels account for 50%. If you are chasing a specific reward at level 15 or 20, you are looking at roughly a quarter to half the total grind.
How to Farm Mastery XP Efficiently
There is no secret trick to earning mastery XP faster. The two sources are variant ownership and Infinity Splits, so your strategy comes down to optimizing those. Stack variants on your priority cards. Every variant you own for a card gives a one-time XP boost based on its rarity. If you are trying to max out a specific card, buying or earning variants for that card is the fastest path. A single Ultimate variant gives 250 XP, which is almost 20% of the total 1,300 needed for level 30. Split your favorite cards repeatedly. Each Infinity Split grants 15 XP. That means roughly 87 splits to go from level 1 to level 30 on split XP alone. For your top 5 to 10 most-played cards, each split stacks up over time. Claim free variants every season. Each season gives out free variants through the Season Pass, missions, and limited-time events. These are essentially free mastery XP.
How Does Mastery Compare to Infinity Splits?
Splits are visual upgrades to a specific card instance. Each split costs 155 boosters and credits, and the result is a random cosmetic outcome (finish + flare combination). Your total split count is a measure of how much you have invested in upgrading card visuals. Mastery is a per-card XP track that unlocks exclusive cosmetics not available through normal splits. Mastery rewards include unique finishes and flares that only appear at specific level milestones. The overlap: splitting a card grants 15 mastery XP per split. So heavy splitters naturally accumulate mastery XP. But mastery also counts variant ownership, meaning collectors who buy lots of variants can reach high mastery levels on cards they rarely split. On SnapComplete, the Splits page lets you sort by either metric.
What Are the Best Cards to Focus Mastery On?
There's no objectively "best" card for mastery since rewards are cosmetic. But some picks make more sense than others. Cards you play the most. If a card is in your main deck, you will naturally accumulate boosters for it, making splits easier. More splits means more mastery XP. Cards with lots of variants. Some cards have many variants across shop bundles, season passes, and special events. The most-varianted card in the game currently has 31 released variants. Owning more variants means free XP. Cards close to milestone levels. Use the mastery rank sort on the Splits page to find cards sitting at level 9, 14, 19, 24, or 29. One more split or variant purchase pushes them over a milestone and unlocks an exclusive cosmetic.
Mastery XP and Leaderboard Rankings
The Card Leaderboards rank every player's mastery level per card against the entire tracked community. These rankings update regularly, and you can see your percentile tier for each card in the card detail view. The six percentile tiers (top 1%, top 3%, top 5%, top 10%, top 25%, and top 50%) give you a quick read on where you stand. If you are in the top 10% for a card's mastery, that means 90% of tracked players have less mastery XP on that card than you do. Premium members can appear on the public card leaderboards with their game name visible.
