Seven Knights Re:BIRTH Hero Enhancement and Fusion Guide

To maintain hero progression in Seven Knights Re:BIRTH without depleting gold or running out of inventory space, feed surplus level 1 fodder directly into upgrade targets, configure auto-selection presets to prevent consuming valuable units, and fuse pairs of fully enhanced heroes to generate higher-tier cards.

Clearing Surplus Level 1 Fodder

Accumulating 1-star and 2-star heroes from adventure drops and summons quickly fills your inventory, which interrupts auto-repeat stages. Instead of expanding inventory slots or holding duplicate low-tier units, consume them directly as enhancement material for heroes you plan to rank up or fuse.

• Gold Conservation: Feeding 1-star units yields small percentage gains per transaction and carries a higher gold-to-experience cost ratio. If gold reserves are tight, prioritize using 2-star fodder first.
• Ruby Milestones: Save at least one copy of each unmastered hero to raise to level 30 for first-time ruby rewards before feeding duplicates into upgrades.

Configuring Enhancement Material Presets

The enhancement preset interface automates material selection while protecting critical units from accidental consumption. Access your hero enhancement menu and adjust the filter rules before using auto-fill:

• Exclude Locked and Assigned Units: Ensure heroes currently locked or placed in combat and expedition teams are excluded from selection queues.
• Filter by Level 1: Restrict auto-fill to level 1 heroes so you never consume units that have reached level 30 and are waiting for fusion or ruby claims.
• Set Tier Thresholds: Allocate 1-star and 2-star heroes to early enhancement stages (+1 through +3). Reserve 3-star fodder for later steps (+4 and +5) where fractional gains risk failing to cap enhancement levels efficiently.

Always glance at the loaded materials before confirming the enhancement to ensure no rare or unintended heroes are included.

Sourcing 4-Star and 5-Star Fodder

Higher-tier fodder depletes rapidly during mid-game advancement. Rather than spending rubies on standard summons to rebuild your stock, gather replacement materials through regular gameplay channels:

When natural 4-star drops run low, farm stages with high drop rates during hot-time events to build up 3-star bases for fusion.

Hero Fusion Rules and Strategy

Hero fusion upgrades star ratings without spending rubies. A fusion requires two heroes of identical star rarity that have both reached level 30 and enhancement level +5. Combining them produces a random hero of the next star tier.

1. Focus on 3-Star Pairs: Maximize and fuse pairs of 3-star fodder heroes first to build a working pool of 4-star units.
2. Advance Duplicate 4-Stars: Once a stable 4-star stock exists, raise duplicate 4-star heroes to level 30 and +5 to fuse into 5-star units for transcendence and awakening fodder.
3. Protect Utility Heroes: Only use generic, easily replaceable heroes as fusion bases. Never feed unique support units or rare synergy characters into the fusion pool.

Weekly Resource Tasks

Complete weekly checklist tasks before scheduled maintenance resets to replenish the currencies and materials needed for daily enhancements:

1. Complete Weekly Quest Milestones: Clear your quotas for adventure runs, arena matches, and enhancements to collect milestone reward chests.
2. Spend Honor Points: Summon fodder using accumulated Honor points to avoid wasting points at the currency storage cap.
3. Clear Event Shops: Purchase discounted hero tickets and enhancement items from limited-time event exchanges before shop timers expire.
