Jugner-forest NM


  • Located around (G-5), typically near the lake. You have to go through King Ranperre’s Tomb to get to this area.
  • His pop method is slightly different than other NMs. Ten Knight Crabs pop 21 hours 5 minutes-24 hours 5 minutes after King Arthro is defeated and after all ten of these Knight Crabs are defeated, King Arthro will spawn 5-10 seconds later. (Example: If Time of death is 6:00pm, the window will begin at 3:05pm the next day and windows will be at the 05 and 35 minute mark.)
    • Knight Crabs rage progressively. The longer that you hold one the more damage it does. They critical often and have increased evasion and accuracy. A Knight Crab held for 20 minutes will critical a fully self buffed with food 75 PLD/WAR for upwards of 400 damage.
    • If one Knight Crab is held for more than 5 minutes, the Knight Crabs will begin to respawn.
  • Instant cast on spells – Waterga IVPoisonga IIDrown, and Enwater. High level players have high resistance to these spells due to King Arthro’s low level.
  • Uses Hundred Fists and has an Additional EffectParalyze on melee attacks.
  • Resistant to Bind and Silence.
  • Resistant to Blood Weapon.
  • Begins to Rage after 20 minutes. Slowly builds to full rage, increasing all stats over time.
  • King Arthro can despawn after 10 minutes if not claimed.
  • King Arthro can drop up to three cloths.
  • Killable by 6 level 62 players (see testimonials).

Everbloom HollowModifica

  • Found in Everbloom Hollow as a result of being warped there via the Doomvoid ability, used by a Sandworm.
  • The Past King Arthro is a stronger version of the Present King Arthro. (It is not raged, just a higher level.)
  • This is a timed, 60 minute battle.
  • Bubble Shower will summon a Knight Crab, which will try to cure him by casting Water IV on him.
    • King Arthro will summon more Knight Crabs throughout the fight and they should be killed.
    • If Knight Crabs are pulled away from King Arthro, they might go back to him to cure him.
    • When King Arthro is below 20% HP, Knight Crabs spawn far more frequently.
  • King Arthro is only damaged by Critical Hits, but at a extremely decreased damage. (Thief crits at 90 were landing for 12.)
  • Found that this above statement is true to some extent, as my NIN/WAR @90 was critting for 80-90 damage per hit. Meat kabobs used, though I didn’t have Kannagi. Most if not all my non-crit’s landed for 1 damage.
  • All Normal Nukes do 0-1 damage.
  • At 90 Critical Hits can land for slightly higher, but not enough to make him killable without a Skillchain.
  • At 99 Critical Hits were landing were 250+, making him easily soloable.
  • Also found this above statement to be false, as I just successfully dual boxed this as 90NIN/WAR and 90WHM/BLM. When knights pop i killed them as quickly as possible so they could only get a single water IV off, and I used my WHM/BLM to stun those. Earlier in the fight stun was used for Waterga IV to conserve mp. (As a sidenote I did have to rest about 1-2k mp back during the fight.)
  • King Arthro will cast Waterga IV frequently.
  • King Arthro will gain resistance to Stun after some time.
  • Water-based spells cure King Arthro.
  • Killable by 4 level 90 players, using Skillchain-Magic Burst.
  • Knight Crabs are easily killed at 90 by a Beastmaster pet.
