Tuning (Syntony) the Guardian Rectifier
Tuning, also known as Syntony, allows players to upgrade the Guardian Rectifier by using surplus materials and duplicate weapons. This process enhances the weapon’s passive skill, Companionship, which increases Basic Attack and Heavy Attack DMG Bonus. As the weapon reaches higher Tuning Ranks, the effectiveness of its passive ability improves, doubling its initial bonus at maximum rank.
The progression of Tuning Ranks is as follows:
Rank 1: +12% Basic Attack and Heavy Attack DMG Bonus
Rank 2: +15% Basic Attack and Heavy Attack DMG Bonus
Rank 3: +18% Basic Attack and Heavy Attack DMG Bonus
Rank 4: +21% Basic Attack and Heavy Attack DMG Bonus
Rank 5: +24% Basic Attack and Heavy Attack DMG Bonus
Reaching Rank 5 maximizes the weapon’s effectiveness, making it a strong choice for boosting Basic and Heavy Attack damage. Since duplicate weapons and low-rarity materials are commonly obtained throughout exploration, utilizing them for Tuning ensures the Guardian Rectifier reaches its full potential.
