Last War Hero Bonds System (2025) | How to Strengthen Heroes and Boost Stats

The Hero Bond system in Last War is one of those features that players often overlook early on but later realize how powerful it truly is. Bonds grant free attribute boosts simply for collecting and upgrading certain heroes. When I first started playing, I ignored this system and focused only on upgrading my combat teams. But once I activated my first few bonds, I noticed a major power spike, especially in attack and troop capacity.

Before diving deeper, make sure you’re managing your in-game resources wisely. If you plan to strengthen heroes faster, you can top up your game resources through LootBar. It’s an efficient and safe way to boost your progress in Last War.

What Is the Hero Bond System?

The Hero Bond system connects groups of heroes together based on specific themes, factions, or abilities. Once you’ve collected the required heroes and met their level or star upgrade conditions, the bond activates automatically, granting your team permanent buffs. These bonds represent the relationships between heroes in the game’s storyline, so activating them feels both strategic and rewarding.

These buffs can enhance key stats such as:

  • Attack power

  • Defense

  • HP

  • March size

In short, Hero Bonds reward you for collecting and investing in heroes you probably already use in your lineup. The more complete your collection, the stronger your account becomes overall, and the easier it is to dominate in both PvE and PvP modes.

How to Activate Hero Bonds

Activating Hero Bonds might sound complicated at first, but it’s actually a simple process once you know what to prioritize. Here’s how to get started:

1. Recruit Specific Heroes

Each bond requires a unique combination of heroes. To unlock them, focus on recruiting through Elite and Red Premium Vouchers. These are usually obtained through events, daily missions, or premium currency.

For example, I once unlocked a powerful bond just by completing a set of Red-grade heroes, and the resulting attack buff completely changed my PVP performance.

2. Level Up Heroes

Once you have the right heroes, use Experience Books to level them up. Hero levels can go up to 120, and reaching higher levels often unlocks stronger bond effects. Always prioritize your main heroes for maximum benefit.

3. Promote Heroes with Hero Shards

Hero Shards are crucial for promotion. Promoting a hero increases their star rating (tier), which is often required to activate higher-level bonds. You can earn Hero Shards from events, the recruitment center, or in-game missions.

If you’re looking to upgrade faster without waiting for event rewards, you can easily top up Last War items through LootBar to get the resources you need without delay.

 

Benefits of Hero Bonds

So why should you care about Hero Bonds? Because they’re one of the most cost-effective ways to gain permanent power increases in Last War.

Here’s what you gain from activating and upgrading bonds:

  • Free Buffs: Bonds don’t cost ongoing maintenance or resources once unlocked. They’re free, passive boosts that stay active permanently.

  • Enhanced Stats: Attributes like attack, defense, HP, and march size are all improved. This means your army hits harder, lasts longer, and travels farther.

  • Synergized Power: When several heroes in your team share multiple bonds, their combined effects can boost your squad’s total combat rating significantly.

When I unlocked three bonds simultaneously for my front-line heroes, my army’s durability skyrocketed, allowing me to withstand attacks that would’ve crushed me before.

 

Tips for Success in the Hero Bond System

Mastering the Hero Bond system requires strategy. Here are a few practical tips based on real gameplay experience:

1. Focus on Key Heroes

Don’t spread your resources thin across every hero you own. Pick a few heroes that appear frequently in bond combinations and level them up first. It’s better to have a handful of strong heroes with active bonds than a large group of weak ones.

2. Plan for Future Updates

The game’s developers often introduce new heroes and expand the bond system. Check the in-game update logs or announcements regularly so you can plan your upgrades efficiently.

3. Track Your Progress

Use the Bond interface to see which heroes are needed for future bonuses. I like to screenshot my active and inactive bonds to keep track of which heroes I need to prioritize next.

4. Time Your Upgrades

If you plan to promote several heroes, do it during event periods that reward player growth. This way, you gain bond progress and event rewards simultaneously, saving both time and resources.

 

Hero Bond System in Action

To see how big a difference Hero Bonds make, try comparing your army’s stats before and after activating a few key bonds. Even minor buffs stack up quickly, especially when you combine attack and HP bonuses.

For example, my Infantry Squad gained nearly 12% extra durability after I activated the “Defenders of Hope” bond, while my Sniper Unit dealt noticeably more damage after unlocking the “Elite Marksmen” bond.

Over time, these incremental upgrades separate top players from casual ones.

Final Thoughts

The Hero Bond System in Last War is one of the most efficient ways to gain permanent strength boosts without extra cost. Whether you’re a casual player or pushing for higher ranks, investing time in activating and upgrading bonds pays off in every battle.
