Seofon Master Traits Progression Step-by-Step

The Master Traits system is a brand-new progression layer introduced in the Endless Ragnarok expansion. It allows you to upgrade characters beyond their base limits, turning Seofon into a specialized powerhouse. Follow these steps to allocate your points efficiently.

1

Unlock Seofon's Base Nodes

Complete his initial character progression paths using standard Master Points. Ensure his basic skill slots and weapon masteries are fully unlocked before diving into Master Traits.

2

Prioritize Sword Energy Generation

Allocate your first Master Trait points into nodes that increase his sword energy generation. This ensures you can summon his Avatar faster during intense fights.

3

Boost Damage Cap Limits

Focus on nodes that raise the damage caps of his physical skills and Skybound Arts (SBA). This prevents his high-scaling attacks from hitting a hard damage ceiling.

4

Enhance Wind Elemental Damage

Invest in wind-specific elemental boost traits. This drastically increases his effectiveness against Earth-type bosses found in the new Chaos quest tiers.

5

Finalize Utility and Cooldowns

Spend your remaining points on skill cooldown reduction and dodge window extensions to increase his overall safety in endgame content.

Important Mastery Warning

Master Traits require rare materials farmed from high-end activities. Do not spread your points too thin across multiple characters early on; focus entirely on completing Seofon's tree first to unlock his true potential.

Endgame Progression Checklist for Seofon

To fully optimize Seofon for the hardest content in the expansion, including Ragnalia boss fights, aim to complete the following checklist.

Seofon Completion Goals:

  • Reach maximum character level with Seofon
  • Fully upgrade the Seven-Star Sword to its highest tier
  • Unlock at least 80% of Seofon's Master Traits tree
