Ys Memoire: The Oath in Felghana progressively introduces challenging bosses, enhancing player mastery of game mechanics. While not excessively long, the game features a satisfying roster of formidable opponents. Gyalva, Lord of the Blazing Prison, presents a significant hurdle, demanding a solid understanding of combat, abilities, and game mechanics.

Following Guilen's defeat, players encounter Gyalva deep within the Zone of Lava. The key to victory lies in strategic positioning: fight from either end of the unstable bridge.
Limited movement options and the bridge's precarious nature necessitate quick attacks and retreats. Utilize wind magic to maximize damage output during brief opportunities. Mastering this dance between offense and defense is crucial.
The Ys series consistently delivers high-quality gameplay, and overcoming bosses like Gyalva provides a rewarding sense of accomplishment.
Gyalva, a unique addition to the remake, boasts a diverse arsenal. While the fight's core mechanics are relatively straightforward, Gyalva's attacks can inflict substantial damage if underestimated. The boss frequently traverses the bridge, launching fiery assaults that disrupt the platforms.
Adequate preparation is strongly recommended. Aim for at least Level 21 and upgrade your equipment. Consistent combat against minor enemies throughout the game will facilitate this.
Gyalva employs two spinning attacks: a localized attack targeting a bridge section and a full-bridge traversal. Both attacks send platforms airborne, posing a significant threat to under-leveled players.
Maintain mobility, striking Gyalva opportunistically before retreating to a safe ledge.
Gyalva unleashes fireballs onto the bridge, launching platforms skyward. While damaging, this attack provides a window to land several hits.
Torches along the bridge periodically erupt in flames, accompanied by a fireball exchange. These unpredictable bursts inflict damage. Wait for the burst to subside before moving through the affected area.
