Seven Knights Re:BIRTH Guide: Best Uses for Level 30 Gikis

Many players in Seven Knights Re:BIRTH may have faced the same situation: farming the character “Giki” (or others not actively used in battle) until they reach max level 30, only to wonder what to do with them next. While some might think of them as leftovers with no value, the truth is that level 30 Gikis can be extremely useful. From powering up your main characters and combining to create stronger units, to unlocking vital equipment slots, these extras still hold value and should never be overlooked.
When it comes to managing Gikis at level 30, here are the most effective ways to maximize their potential:
Upgrade Your Main Characters

The most direct use of Gikis is as materials to enhance your main heroes, including essential support characters needed for dungeons. Having stronger core units allows you to progress through stages, PvP, and Raids with much greater ease. Planning which characters to upgrade with Gikis ensures efficient growth of your team.
Smart Upgrade Formulas
Gikis come in star levels from 1 to 3, and their success rates vary:
- 3-star Giki with a 6-star hero gives the highest upgrade chance.
- 2-star Giki with a 5-star hero offers the best balance.
- 1-star Giki generally has very low success, making it less worthwhile.
Choosing the right star level helps save resources while boosting your chances of success.

Combine to Create New Heroes
Level 30 Gikis can also be combined in the Hero Fusion system to create higher-rarity heroes, such as:
- 3-star Giki fusion → results in a 4-star hero (with a chance to obtain rare characters like Biscuit).
- 4-star Giki +5 → becomes a 5-star hero.
- 5-star Giki +5 → can yield a 6-star hero or even a Legendary unit.
Even if you end up with another Giki, these can still serve other useful purposes such as unlocking slots.

Unlock Equipment Slots
Even unwanted 6-star heroes obtained from fusion can be repurposed. They can unlock additional slots for weapons, armor, and accessories, which are critical for boosting the overall strength of your team. This makes Gikis extremely valuable in the long run.

Exchange in the Craft Room
Finally, Gikis can be exchanged in the Craft Room for useful heroes needed in dungeons, such as Victoria, Lucy, Karin, or Asura. This ensures you have a complete lineup for dungeon and Raid content, giving your account more flexibility and power.
