Why Great Sword Excels Against Omega Planetes?

Great Sword stands out as one of the premier weapon choices for facing Omega Planetes, and for good reason. According to extensive research from Game8 and community testing, Great Sword scores a perfect 3/3 stars for sever damage effectiveness against this mechanical menace.

Key Advantages:

• Perfect Sever Damage: Great Sword delivers maximum sever damage to Omega Planetes’ most vulnerable parts
• Natural Tank Capabilities: Built-in guarding abilities make it ideal for the tank role in team compositions
• High Single-Target Damage: Perfect for focusing on specific breakable parts
• Thunder Element Synergy: Pairs perfectly with Thunder element, Omega Planetes’ primary weakness

Optimal Hitzones for Great Sword

Knowing where to strike is just as important as what weapon you use. Based on detailed hitzone analysis, here are the optimal targets for your Great Sword:

Hitzone	Sever Effectiveness	Recommended Strategy
Hind Legs	★★★ (Highest)	Primary target for maximum damage
Rear Power Unit	★★★ (Highest)	Focus here when accessible
Back	★★☆ (Good)	Alternative when legs/power unit are hard to reach
Forelegs	★★☆ (Good)	Secondary target for consistent damage
Head	★★☆ (Good)	High-risk, high-reward target

Pro Tip: Always prioritize the Hind Legs and Rear Power Unit for maximum damage output. These areas not only take the most damage but are also crucial for breaking parts and triggering phase transitions.

Advanced Combat Strategies (2026)

Positioning and Movement

Omega Planetes is a highly mobile boss with complex attack patterns. Here’s how to position yourself effectively:

During Normal Phase:

• Stay near the Hind Legs for consistent damage
• Keep your weapon sheathed when moving between positions
• Use the environment to block line of sight during laser attacks

During Pantokrator (Enraged Phase):

• Focus on breaking leg wounds quickly to trigger phase transitions
• Use Guard stance more frequently due to increased attack frequency
• Position yourself near the Rear Power Unit when accessible

Tank Role in Team Composition

If you’re playing as the designated tank in a four-player team, your responsibilities include:

1. Aggro Management: Use True Charge Slashes and tackles to maintain enmity
2. Damage Mitigation: Block attacks that would otherwise one-shot DPS players
3. Positioning: Keep Omega Planetes facing away from your team
4. Part Breaking: Focus on breaking specific parts to team coordination

Pro Tip: Use a custom shoutout to inform non-tank players to attack the legs instead of the head. This prevents them from accidentally pulling aggro and getting destroyed by Omega Planetes’ devastating attacks.

Solo Play Adaptations

When playing solo, you’ll need to balance offense and defense more carefully:

1. Mantle Usage: Rocksteady Mantle for damage prevention, Temporal Mantle for emergency situations
2. Item Management: Bring Mega Potions, Max Potions, and Adamant Seeds
3. Environmental Usage: Utilize rockburst and thunder slinger ammo to interrupt attacks
4. Patience: Wait for clear openings rather than forcing attacks

Omega Planetes Attack Patterns and Counters

Understanding Omega Planetes’ moveset is crucial for survival. Here are the most dangerous attacks and how to counter them with Great Sword:

Delta Attack

• Description: Omega Planetes generates a Nerscylla clone before unleashing a devastating area attack
• Counter: Guard through the initial blast, then position for a True Charge Slash on the legs
• Danger Level: ★★★★★

Wave Cannon

• Description: Laser attack that shoots semicircles from left or right
• Counter: Evade through the laser or guard if positioned correctly
• Danger Level: ★★★★☆

Omega Micros

Team Composition and Coordination

Ideal Four-Player Team Setup

Healer	Sword & Shield	Healing, buffs, Wide-Range support
DPS 1	Thunder Dual Blades	Maximum damage on legs and weak points

Communication Strategies

1. Use Preset Shoutouts: Create custom messages for:
   • “I have aggro, attack the legs!”
   • “Healing needed at rear legs”
   • “Breaking part now, focus fire”
2. Position Markers: Use the ping system to indicate:
   • Safe zones during area attacks
   • Target parts for breaking
   • Healing locations
3. Mantle Coordination: Stagger mantle usage to ensure constant protection

2026 Progression and Gear Improvement

Common Mistakes to Avoid

1. Ignoring Guard Up

Many players underestimate the importance of Guard Up 3. Omega Planetes has several attacks that cannot be blocked without this skill, making it absolutely essential for survival.

2. Poor Positioning

Standing in front of Omega Planetes without Guard Up active is a death sentence. Always position yourself at an angle where you can evade or block incoming attacks.

3. Neglecting Thunder Element

Using raw damage Great Swords instead of Thunder element significantly reduces your effectiveness. Thunder is consistently 30-50% more effective against all of Omega Planetes’ hitzones.

4. Forgetting About Team Composition

Playing solo with a team-oriented build, or vice versa, leads to suboptimal performance. Adapt your build and playstyle to your group size and composition.
