Attack on Bionis

Learn how to defeat the Sureny Telethia in Xenoblade Chronicles: Definitive Edition. This guide covers boss stats, weaknesses, and strategies to overcome this challenging encounter.

Boss: Sureny Telethia

• Level: 70
• Detection: Sight

Stats / Weaknesses:

• The Sureny Telethia's main threat is its Soul Read Art, which prevents Physical attacks from landing. If your party is heavily Physical-based, you will struggle. Having Melia as party leader with Mind Blast can negate this threat.
• You only need to deplete 50% of its HP to conclude the battle.

Sureny Telethia's Arts:

• Burst Animus: Ether-based Art dealing light damage in a circle, inflicting Arts Seal, Bind, and Knockback.
• Ether Particles: Ether-based Art dealing massive damage in a frontal arc, inflicting Ether Defence Down.
• Killer Sky: Ether-based Art dealing massive damage to a single target, inflicting Topple and Knockback.
• Killer Shot: Ether-based Art dealing light damage to a single target, inflicting Chill, Ether Defence Down, and Knockback.
• Killer Tail: Physical-based Art dealing major damage to a single target, inflicting Knockback.
• Mega Ether Particles: Used when HP drops below 70%, ending the battle.
• Soul Read: Grants an Aura that prevents Physical attacks from landing.

Strategy:

• Focus fire on the Sureny Telethia.
• Utilize Melia's Mind Blast Art to counter the Soul Read Art if your party is not Physical-based.
• Since you only need to deplete 50% of its HP, go all out to avoid its devastating Arts as much as possible.
• The battle will conclude once you reach the 50% HP mark.
