Complete Seth Lowell Material Checklist

Before you dive into the grind, here's a quick look at all the key items you'll be hunting for:

  • Defense Certification Seal (Primary Ascension Material)

  • Shock Chip (Elemental & Skill Material)

  • Higher Dimensional Data: Falling Fist (Normal Boss Drop)

  • Living Drive (Weekly Boss Drop)

  • Hamster Cage Pass (Basic Skill Material)

  • Expert Challenge / Notorious Hunt Drops (Core Skill Material)

Ascension Materials: Building the Foundation

Ascending Seth is your top priority to increase his level cap and base stats. His requirements are themed around his role as a sturdy defender.

🔧 Primary Ascension Mats:

The core of Seth's leveling revolves around Defense Certification Seals. These are farmed from specific combat simulations or resource stages that reward defense-type materials. Plan your daily energy usage around these stages.

⚡ Elemental & Boss Materials:

  1. Shock Chips: As an Electric attribute agent, Seth needs a hefty stack of Shock Chips. These are commonly dropped from enemies weak to Electric damage or found in designated resource collection areas.

  2. Higher Dimensional Data: Falling Fist: This material is obtained by defeating a specific Normal Boss in the game. Unlike Weekly Bosses, this enemy can be farmed repeatedly as long as you have the necessary stamina, making it a reliable, if grindy, source.

  3. Living Drive: This is the coveted Weekly Boss material. You'll need to challenge a particular high-difficulty boss once per week to claim this reward. Prioritize this weekly challenge—it's time-gated, so you don't want to miss out!

Skill Enhancement: Unlocking True Potential

Once Seth is ascended, you'll want to boost his abilities. The process is split into basic skills and his powerful Core Skill.

🎯 Leveling Basic Skills:

This is the simpler part. Enhancing Seth's standard attacks and abilities primarily requires:

  • More Shock Chips (you'll need a lot of these!).

  • Hamster Cage Passes, a common currency obtained from various daily activities and mission completions.

💥 Maxing the Core Skill:

Seth's Core Skill is where his real defensive utility shines, and upgrading it requires special, high-end materials:

  • Expert Challenge - Rampant Brute Material: You'll need to tackle the Expert Challenge mode featuring the "Rampant Brute." These challenges are tougher than standard content but offer unique upgrade resources.

  • Notorious Hunt - Unknown Corruption Complex Material: The final tier of materials comes from Notorious Hunt events, specifically the "Unknown Corruption Complex" target. These are limited-time elite hunts that test your team's mettle and reward the rarest components.

2025 Farming Strategy & Pro Tips

🗓️ Weekly Planning is Key:

  1. Monday: Focus on farming Defense Certification Seals and Shock Chips.

  2. Tuesday-Thursday: Grind the Normal Boss for "Falling Fist" data.

  3. Friday-Sunday: Reserve your best team for the Weekly Boss (Living Drive) and any active Expert Challenges or Notorious Hunts.

💡 Efficiency Notes:

  • Always use your daily energy efficiently on material stages.

  • Save your "Hamster Cage Passes" specifically for your main agents like Seth.

  • Team Seth with other Electric or support characters to clear farming stages faster.

  • Keep an eye on the in-game event schedule for double-drop events on material stages!
