If you’ve been grinding through Infinity Nikki’s open world for even a few hours, you’ve likely stumbled across diamonds as one of the rarest drops in the game. You might have hoarded your first few dozen without a clue what to use them on, and that’s a super common problem for new players who don’t want to waste hard-earned resources. I’ve put 120+ hours into the game across two accounts, so I’ve made every possible mistake with diamond spending first hand, and this guide breaks down exactly what are diamonds for in Infinity Nikki, plus how to get the most value out of every single one you earn.
What Are Diamonds For in Infinity Nikki: Core Usage Categories
Diamonds are the game’s only universal premium currency, and they work for almost every special purchase you can make outside of regular gold-bought store items. Unlike a lot of gacha games, you can’t use diamonds to buy power or skip progression, which keeps the playing field fair for free-to-play and paying players alike. Diamonds are the only in-game currency that can be used to pull on limited-time event gacha banners, which is their most popular use for most players.
You can also use diamonds for quality of life upgrades, exclusive limited-time accessories, wardrobe storage expansions, and special event entry tickets that come with extra rare rewards. Some players even use diamonds to buy fast travel passes if they spend a lot of time exploring the far corners of the open world and don’t want to run between map points. There’s no right or wrong way to use them, but some spends give way more long-term value than others.
The Highest-Value Ways to Spend Your Diamonds
Knowing what are diamonds for in Infinity Nikki is half the battle, but prioritizing the right spends is how you get the most out of every free or paid diamond you earn. Always prioritize limited-time event gacha sets first if you love the design, because they never come back to the store at the same low pull price once the event ends. I skipped a cherry blossom themed set last event because I thought I could get it later, and now it’s only available in a special premium pack that costs 3x the original pull price.
Next, if you don’t care for the current event’s sets, save your diamonds for upcoming events that have pieces you know you’ll use often. Other high-value spends include:
- Limited-time event gacha pulls for sets you genuinely love, as they do not return to the regular store at their original pull price
- Wardrobe slot expansions once you hit 80% of your current storage limit, to avoid having to delete rare event pieces
- Exclusive styling contest entry tickets if you’re competing for top 100 leaderboard rewards that include rare accessories
- Open world fast travel pass bundles if you spend 2+ hours a day exploring and hate running between far apart map points
Character wardrobe expansion slots are an underrated pick for collectors, because you’ll hit your storage limit way faster than you think once you start earning free event outfits and open world rewards. I had to delete three rare event hair pieces my first month playing because I ran out of space and refused to spend 20 diamonds on extra slots, and I still regret that call.
Spends You Should Almost Always Avoid
There are a lot of low-value purchases in the game that look tempting at first glance, especially when you’re a new player short on gold or resources. Never spend diamonds on single pull tickets for the permanent gacha banner, because you get free single pulls every day from daily missions, and the permanent set drops are super common even from free event rewards. I wasted 100 diamonds on permanent banner pulls my first week playing, and I got three duplicate common hair clips that I never used once.
You should also never buy gold with diamonds, even if you’re short on it right now. You can earn 100k+ gold a day just from doing daily quests and collecting open world chests, so spending diamonds on gold is a total waste of rare resources. Skip the temporary exploration buffs like speed boosts or extra stamina refills too, unless you’re on a super tight deadline to finish an event before it closes. Avoid impulse buys on random store accessories that you'll only wear once, because those diamonds add up fast, and you’ll wish you saved them for a set you actually love when the next event rolls around.
How to Earn Extra Diamonds Without Spending Real Money
You don’t have to spend a cent to earn hundreds of diamonds a month if you know where to look. First, explore every hidden corner of the open world: every hidden chest gives between 5 and 20 diamonds, and there are over 2000 hidden chests across the full map right now. I’ve earned almost 3000 diamonds just from exploring hidden caves, mountain tops, and small island areas that most players skip.
Weekly styling contests also give out diamond rewards for anyone who ranks in the top 50% of participants, even if you don’t have a huge wardrobe of rare sets. You can also earn 15 diamonds a day for finishing all daily quests, plus 50 extra diamonds a week for finishing all weekly missions, which adds up to almost 400 diamonds a month just for logging in and doing basic tasks. If you complete 100% of the map exploration for each region, you get a one-time reward of 200 diamonds per region, which is a huge boost for new players who like wandering the world instead of just doing main quests.
At the end of the day, how you spend your diamonds is totally up to your personal playstyle, whether you're a casual player who only collects cute outfits or a competitive player who climbs the styling contest leaderboards every week. Don't let anyone pressure you into spending your diamonds on things you don't care about, because the game is designed to let you play at your own pace without feeling forced to spend real money. Now that you know what are diamonds for in Infinity Nikki, you can make smarter choices with your currency and avoid the mistakes I made when I first started playing. You'll be able to save up for all the sets you love without wasting a single diamond on low-value purchases.
