How to Beat Argon Kelsaik (Kelsaik's Nest)

Learn the best strategies and weaknesses to defeat Tera in TERA's Kelsaik's Nest. This guide covers boss mechanics, recommended party members, and essential tips for victory.

Stats / Weaknesses:

• Tera Vulnerable: Dagger, Axe, Staff, Ice, Darkness
• Tera Vulnerable (Yellow Health): Axe, Ice, Darkness
• Tera Vulnerable (Red Health): Ice, Darkness

Phases:

1. Initial Phase: Tera has a wider range of weaknesses. Focus on breaking its shield (max 6 points) quickly.
2. Hardened Shell: Tera lowers its weaknesses and becomes more resistant. Focus on survival and buffing.
3. Red Health Phase: Weaknesses are further reduced, but the fight intensifies.

Strategy:

• Party Composition: Highly recommend party members with Ice and Darkness abilities (e.g., Osvald, Scholar sub-job). Healing is crucial (Temenos, Cleric). Castti and Throné are also very effective.
• HP Management: Aim to keep party members above 1200 HP. Consider debuffing Tera's attack (Thief) or buffing your party (Apothecary/Castti).
• Attack Timing: Avoid attacking when Tera uses "Coiling Lava" to prevent self-inflicted damage. Use this time to buff or heal.
• Sneeze Mechanic: When Tera "sneezes" a party member out, focus on maintaining the rest of the party's health. The removed member will return after 4-5 turns or when Tera is broken.
• Healing: Utilize healing skills like Ochette's "Cleaving Blow" which heals herself. Keep a healthy supply of "Olives of Life" for revivals.
• BP Management: Save Break Points (BP) for powerful attacks from your main damage dealers.
• Weakness Exploitation: Consistently hit Tera's weaknesses to break its shield and interrupt its powerful attacks.
