Mylen Ploa

Mylen Ploa joins in second and later playthroughs if you turn EX-events On when starting a new game. In an EX-event, Wil picks up a magical black pearl belonging to Mylen in Wartorn Ruins. Upon his return to his workshop, Wil is confronted by Mylen, demanding its return. After learning that she intends to use the power of the black pearl for evil, Wil refuses to return it, and as a result had to confront and defeat Mylen in battle in the Gushimera Temple. Upon defeating her, Wil decides to teach her to understand humans and why it is wrong to kill.

Role
Mylen is one of the best side characters you can recruit, having Double Action from the start, no elemental weaknesses, and excellent initial stats (especially Str, Spd, and Evd). These along with Prevail skills more than offset any weaknesses from average Con and Res and relatively low HP for a melee fighter. Although she is best suited towards melee combat, Hellfire Cage (and its upgrades) along with the ability to use orbs give her solid range attack abilities. Explosive Assault is utterly devastating to opponents weak to fire, and Ferocity adds to her already potent offensive power.

Equipped with a Naqua Ninja Blade, she can be a quick explorer of hidden rooms in addition to having a chance of inflicting Death. Compared to Yuela, Mylen has better overall stats and higher Evd, but lacks Yuela's massive skill set (including flexibility from the varied sword dances and an AoE attack). Mylen has one of the highest command costs in the game, but is well worth it.

Weapons: Swords, Crystals, Claws

Join condition: NG+, quest 083 (requires picking up Ebony Pearl in Chaotic Warground - Wartorn Ruins)

Classes
1 歪魔 literally means "warped devil", KanJi reads "Waima"

2 Due to a mistake in translation, second English title is same as first one. In fact, her second title could be translated as "Space compressing warped devil princess".
