WHERE & HOW TO FARM

Where to farm

Talk to Selazar in Cernium Square after completing [Cernium (After)] Defensive Tactics.

High Mountain is a solo weekly Epic Dungeon with ten ordered stages. Monster stages build Mitra’s Authority, which powers stronger skills for clearing waves and special monsters; boss stages test survival and timing. Completing the run and speaking with Selazar gives the base reward, including a world-specific Sol Erda Fragment amount. Epic Dungeon clear limits are shared across types, so use the weekly account allowance deliberately.

GET STARTED

How to farm

Before you go

  • Level 260 or higher
  • Complete [Cernium (After)] Defensive Tactics
  • Ability to complete a solo staged dungeon
  • An available weekly Epic Dungeon clear
  1. Speak with Selazar in Cernium Square and enter High Mountain.
  2. Proceed through the ten stages in order; you may leave between stages and re-enter to continue.
  3. On monster stages, defeat enemies to fill Mitra’s Authority gauge.
  4. Transform into Mitra and use the special attacks to clear dense waves and blue-marked special monsters efficiently.
  5. On boss stages, watch patterns and use the Mark of the Sun when it appears to recover health.
  6. Defeat Tynos in the final stage, handling its split phase before using the prompted Mitra Flare interaction.
  7. Speak with Selazar after completion and claim the reward, selecting the available reward option that fits your goals.

Farming tips

  • At full Authority, Unleash Authority temporarily makes Mitra’s skills free; use it while waves or special monster formations are present.
  • Potion use is locked in boss stages, so preserve the dungeon’s death counts and use map recovery when available.

Repeat, collect and use

One clear per character each week, with a total of three Epic Dungeon clears per account per week; the allowance resets Thursday. The reward is not an unlimited farm.

Common mistakes

  • Entering without the prerequisite quest; finish Defensive Tactics first.
  • Using ordinary attacks on special formations when Mitra’s abilities are designed to clear them; build Authority and transform.
  • Forgetting the shared account allowance; reserve clears for the Epic Dungeons you can complete.

When to stop or switch

Stop after claiming Selazar’s reward for the week. Continue with another Epic Dungeon only if you still have an account clear available and want that dungeon’s reward.
