As a dedicated AFK Journey player, I’ve spent countless hours exploring every nook and cranny of the game to understand the best ways to build my hero collection. The cornerstone of this endeavor is acquiring Invite Letters, the precious currency that fuels the gacha system at the Noble Tavern. I remember when I first started, I was overwhelmed by the different types—Epic, Rate-Up, and All-Hero—and how to get them. Isn’t it fascinating how a well-planned farming strategy can completely change your progression? Over the years, I’ve mastered the art of obtaining these letters without solely relying on my wallet. In this guide, I’ll share my personal insights and the most effective methods I use in 2026 to stockpile every type of Invite Letter.
🌟 Farming All-Hero Invite Letters: The Accessible Foundation
In my experience, All-Hero Invite Letters are the most straightforward to accumulate. They form the reliable backbone of your summoning resources. Here are the methods I rely on daily.
Honor Duel (PvP) is a thrilling test of your team’s mettle. I make it a point to participate regularly. You get three HP per round, and the goal is to win nine battles. The real prize for me? Winning 15 matches in this mode nets you two All-Hero Invite Letters, alongside Diamonds and Gold. It’s a consistent weekly source.
The Dream Realm is my daily ritual. Facing bosses like Snow Stomper, Skyclops, Necrodrakon, and King Croaker across five difficulty levels is a great challenge. Each victory, especially when unlocking a new difficulty, rewards you with All-Hero Letters. It’s a perfect blend of combat practice and resource gathering.
Legend Trial is arguably the most rewarding PvE activity for letters. I’ve spent hours climbing the four faction-specific towers:
-
Tower of Light (Lightbearers only)
-
Tower of Nature (Wilders only)
-
Tower of Eternity (Graveborn only)
-
Tower of Will (Maulers only)
Each tower has 90 floors, and every fifth floor grants rewards, including All-Hero Invite Letters. It’s a long-term project, but the payoff in Essence, Arcons, and, most importantly, letters is immense.
Don’t underestimate the humble AFK Stages and world exploration.
-
AFK Stages: Progressing through the main campaign stages periodically rewards All-Hero Letters. I always keep an eye out for those green chests; they often contain Equipment and, you guessed it, more letters!
-
World Map Chests: As I traverse the beautiful world of Esperia, I open every chest I find. While not all contain letters, many do, making exploration doubly rewarding.
Limited-Time Events are golden opportunities. Events like Expert Dueler (which focuses on Honor Duel tasks) have been a staple. By completing Easy and Difficult tasks, I’ve earned points to redeem for 10 All-Hero Invite Letters and even exclusive skins like the Creek Vines for Parisa. The key is to always check the current events tab!
⚔️ Securing Epic Invite Letters: The Strategic Grind
Epic Invite Letters are rarer and require more targeted effort. They are crucial for the Epic Recruitment banner. Here’s my strategic approach to farming them.
The Growth Path is my go-to for structured progression. It features multiple stages, each with four missions. Completing a stage reliably grants at least one Epic Invite Letter. I treat these missions as my daily to-do list.
The Arcane Labyrinth is a weekly challenge I never miss. Resetting every Monday, it has 15 difficulty levels with specific entry requirements (like Resonance Level). The first-time clear reward for each difficulty is a whopping three Epic Invitation Letters. I always ensure my best heroes are ready for this mode.
The Noble Path (Battle Pass) is a consistent source. By completing Daily, Weekly, and Epic missions, I earn milestone points. Several milestone levels reward Epic Invite Letters. Purchasing the premium pass yields even more. It’s a straightforward return on investment for active play.
Guild activities foster community and reward dedication.
-
Battle Drills & Reputation Treasure: Participating in my guild’s Battle Drills and completing related tasks fills the Reputation Treasure meter. Each of its four levels grants at least one Epic Letter.
-
Chest of Valor: This guild-specific gacha uses Treasure Keys earned from Battle Drills. While the pull rates are low (1.5% for Epic, 3.0% for All-Hero), every key is a chance for a bonus.
World Exploration has a special tier for Epics: Crimson Treasures. These are locked chests guarded by enemies. The number of guards indicates the chest’s level. Defeating them all to claim the treasure, which always contains Epic Invite Letters, feels like a mini-boss fight in the open world.
Limited-Time Events often have Epic Letter rewards too. Events like Forward Journey, which tasks you with reaching specific AFK Stages, offer points that can be exchanged for Epic Letters. I always prioritize these event tasks.
💎 The Elusive Rate-Up Invite Letters & Smart Exchanges
Here’s the hard truth I had to accept: You cannot directly farm for Rate-Up Invite Letters. These are reserved for the limited-time banners featuring a boosted hero, like the S-Level Vala (a Rogue) I saw recently with a 3% drop rate. My methods for acquiring them are:
-
Diamond Exchange: At the core, one Rate-Up Letter costs 300 Diamonds (3,000 for a 10-pull). This makes Diamonds an incredibly valuable resource.
-
Real-Money Purchase: The in-app store offers direct packages. I budget carefully for these, usually during a banner for a must-have hero.
The Emporium is my hub for converting resources. Accessed via the Mystical House, it has two key stores:
-
Guild Store: Allows me to buy All-Hero and Epic Invite Letters for Diamonds.
-
Recruitment Store: Lets me exchange Dolly Tickets (earned from any summoning) for letters.
This system encourages me to spend all types of currency wisely, always keeping an eye on future banners.
📈 My Personal Farming Strategy & Final Thoughts
After years of playing, I’ve developed a routine that maximizes my Invite Letter income without burning out. Why leave resources on the table when they’re there for the taking?
My Daily/Weekly Checklist:
| Activity | Frequency | Targeted Letter | Key Tip |
|---|---|---|---|
| Dream Realm Boss | Daily | All-Hero | Push the highest difficulty you can. |
| Honor Duel | Daily/Weekly | All-Hero | Aim for the 15-win reward. |
| AFK Stages/World Chests | Daily | All-Hero | Explore thoroughly! |
| Growth Path Missions | Daily | Epic | Clear stages systematically. |
| Guild Battle Drills | Daily | Epic | Be active in your guild. |
| Arcane Labyrinth | Weekly (Mon) | Epic | First-time clears are essential. |
| Legend Trial Floors | As able | All-Hero | Focus on one tower at a time. |
| Event Tasks | During Events | Both | Prioritize limited-time rewards. |
Remember: Diamonds are the universal key. I hoard them for Rate-Up banners or strategic purchases in the Emporium. The journey to build the ultimate team in AFK Journey is a marathon, not a sprint. By understanding and leveraging every game mode, event, and exchange system, I’ve been able to summon the heroes I need to tackle the toughest content Esperia has to offer. The satisfaction of pulling a powerful new hero with letters I earned through strategy and effort is what keeps me logging in every day. Now, go out there and fill your inventory! What will your first summon be?
