Lighthalzen Bio Lab

Four floors under Lighthalzen. Floors 1-2 have lab mobs; floors 3-4 have deadly 2nd-class undead clones using full class skills. Party required for floors 3-4. Best cards in the game here.

Four floors of biological research labs under Lighthalzen. The most dangerous regular dungeon in the game for non-MVP content. Floors 1-2 have mixed lab mobs from levels 81 to 141. Floors 3-4 are filled with undead copies of 2nd-class characters at level 140-160, each using their class's full skillset. Group play is required for floors 3 and 4 unless you are a fully-geared 4th-class character.
⚠️Floor 3 and 4 mobs are Human-type enemy players made undead. Lord Knight Seyren uses Bowling Bash. High Wizard Kathryne uses Storm Gust. High Priest Margaretha uses Heal and status. Sniper Cecil uses Double Strafe. All of them together will kill any solo player fast. Bring a full party or avoid floors 3-4. 💡Floors 1-2 are soloable at high 3rd-class. Remover (Undead, Lv 121) on floor 1 is weak to Holy and Fire. Use Turn Undead or Magnus Exorcismus if you are an Arch Bishop.

Access

Travel to Lighthalzen. Enter the factory/lab building in the south part of the city (lhz_in01). A warp inside sends you to floor 1.
Use the Kafra or airship to reach Lighthalzen.

Floor Details

Floor 1 (lhz_dun01) -- Levels 80-140

Remover (Remover, Lv 121, Undead) fills most of the map (101 spawns). The six named lab mobs appear in small groups: Kavach Icarus (Kavach Icarus, Wind), Errende Ebecee (Errende Ebecee, Holy), Laurell Weinder (Laurell Weinder, Ghost), Wickebine Tres (Wickebine Tres, Poison), Armeyer Dinze (Armeyer Dinze, Earth), Egnigem Cenia (Egnigem Cenia, Fire). Metaling and Anopheles (lower-level fillers) also appear.
Lab NPCs on floor 1 drop their cards. Each card adds +1 to a stat. Multiple copies can be combined for strong set bonuses.

Floor 2 (lhz_dun02) -- Levels 120-145

All six lab NPCs appear in 50-spawn groups alongside each other. Much denser than floor 1. Gemini-S58 (Gemini-S58, Lv 135, Water) also appears.
MVP (Floor 2): Egnigem Cenia (Egnigem Cenia MVP, Lv 141, Fire) spawns on floor 2. Drops Egnigem Cenia Card and rare equipment.

Floors 3-4 (lhz_dun03, lhz_dun04) -- Levels 140-162

Floor 3 has six 2nd-class undead clones at level 140-142 (Seyren, Kathryne, Margaretha, Howard, Cecil, Eremes) alongside their level-160 super versions. Floor 4 replaces them with the Renewal-era 3rd-class versions (Randel, Flamel, Celia, Chen, Gertie, Alphoccio, Trentini) in the same pattern.
⚠️Every clone on floors 3-4 uses its class's strongest skills. Approach mob by mob with a tank. Never stand in a Storm Gust or near a heal-bombing High Priest clone.
