How to get more Diamonds in Lost Sword
In Lost Sword, Diamonds are the core premium currency used for summoning top-tier characters, pets, and progressing faster through the game.

Managing it wisely can make a major difference in your overall strength. Based on everything I’ve experienced so far, here are the most effective ways to earn more Diamonds without spending real money.
1. Pre‑registration and Launch Rewards
If you started playing Lost Sword around its official launch period, then you likely received a generous welcome gift via pre-registration rewards. These early bonuses are a one-time claim, but they provide a huge head start, often including thousands of Diamonds, character summon tickets, and more.
These launch rewards are typically found in your in-game mailbox, and they’re a celebration of Lost Sword reaching player milestones and more. If you haven’t claimed them yet, check your mailbox ASAP! And in the future, keep an eye out for special campaigns or regional launches where similar rewards might return.
2. Rewards from Daily Login
Never underestimate the power of showing up daily. Lost Sword rewards consistent players with daily login bonuses that often include a small stash of Diamonds, especially during special weeks or celebration events.
The game features rotating login calendars, where logging in for 7 days can unlock cumulative Diamond rewards alongside other free goodies like gold, upgrade materials, and summon tickets. Even missing a day doesn’t always reset your streak, so it’s a low-effort, high-reward system. Just open the game every day, even if you don’t plan on playing much, and let those Diamonds stack up over time.
3. Claim the Daily, Weekly, and Epic Mission Rewards
Missions are your bread and butter when it comes to earning a consistent flow of Diamonds. Lost Sword features a robust task system divided into Daily, Weekly, and Epic tasks. This includes simple tasks like clearing stages, enhancing characters, or logging in.
They offer modest amounts of Diamonds, but since they refresh daily, they add up quickly. So, check your Missions tab daily and prioritize these tasks, cause it’s one of the most reliable ways to keep your Diamond income steady.
4. Progress the Main Story and clear each Stage
One of the easiest and most rewarding sources of free Diamonds lies within the game’s Main Story. Each time you clear a new stage or complete a chapter for the first time, you’ll receive Diamonds and other items. So, to maximize your Diamond gain, progress as far as you can in the main story. The story progression is fun, immersive, and one of the best ways to stack Diamonds as a beginner and even as a mid-game player.
5. Claim your free Event and Season Pass rewards
Lost Sword is packed with limited-time events and season pass events that offer tons of Diamonds, especially to active players. Most events have a free track that includes daily objectives and milestone rewards. Completing them can unlock exclusive items, summon tickets, and yes, plenty of Diamonds.
Even if you don’t purchase the premium track of the Season Pass, the free track still gives out a generous helping of Diamonds if you play regularly and clear objectives. Time-limited events also tend to bring special minigames or tasks with individual Diamond rewards per stage.
Where to Spend your Diamonds in Lost Sword
The Summon section is where the magic happens. This is the main place you’ll spend your Diamonds, and rightly so. Pulling on the character and pet banners gives you a chance to recruit high-tier warriors and essential companions that define your team’s potential.

Each banner typically features a mix of five, four, and three-star heroes and pets, with special limited-time banners offering boosted rates for meta-defining units. Additionally, another way to use your Diamonds is in the in-game shop.
Here, diamonds can be exchanged for materials such as Gold box, Boss Raid Ticket, Party Raid Ticket, and more. You can spend your Diamonds under the Exchange Shop section in the Shop menu.
Final Thoughts
Diamonds are very important to your Lost Sword journey. From summoning powerful heroes to in-game purchases, having a steady flow of Diamonds ensures you stay competitive, without going broke.
By mastering the earning methods above and being smart with how you spend, you’ll build up your team, unlock powerful gear, and progress through the toughest content in no time. Stay consistent, keep an eye on events, and don’t forget to check your mail!
