Monster Codex Guide: The Best Cores! – Updated to lvl 260
December 14, 2018

The Monster Codex is your collection of Monster Cores. Each core provides a certain stat and increases them permanently; bonuses vary depending on the Monster Grade.

The stats applied upon completing the Monster Codex can be reviewed in detail in the Codex Window. Once filled, the Monster Codex is activated. Players can then review detailed information about the monsters.

Players can acquire Monster Cores by hunting monsters in each region, from Summon Boxes, and by completing Hard Clan Dungeons. There is a higher chance to acquire Monster Cores from hunting named monsters.

Why Are Monster Cores Important?

Monster Cores add permanent stats to your Character, just like Runes and Elixirs. Their stat additions are essential in giving you a much-needed edge as an individual, and the capability to battle higher level monsters/bosses/players. This is what separates good from great: with complete sets of cores, you have the confidence to win in battles. Unlike Equipment stats, Monster Core stats are HIDDEN, which means cores are essentially your secret arsenal. Since they are hardly filled and requires hardcore farming, you can expect that, in PvP, enemies you meet will have a different core prioritization. Make sure to first fill up the cores that bring out the best of your Character type.

Respawn Timers

Bosses in the field have specific respawn timers. The duration depends on the Grade of the monster. There are a total of 5 grade types for Bosses: C, B, A, S, R. 

GradeRespawn Time Color
C5 minutesWhite
B10 minutesOrange / Pink
A30 minutesGreen
S4 hoursBlue
RClan Dungeon Raid Boss-
  • Grade-A Bosses only spawns in Elite Dungeons
  • Grade-S Bosses are also known as Field Bosses
  • Grade-R Bosses’ Cores are obtained as rewards for clearing the Hard Mode for the Clan Dungeon Raids.

Joining an active clan is important, since Grade-R cores can only be obtained through Clan Dungeon Raids.

    So should I just focus on grade A monsters then?

    • DK
      November 27, 2017 at 3:39 pm

      hi Chad!

      No. Monster grades are categorized based on respawn rate and not the core quality. Some Grade C cores are harder than Grade A cores due to level differences and territory.

      Grade A Noble Ant Leader Lvl 84
      Grade C Langk Lizardman Ranger Lvl 132

      Similarly, the Grade C core above provides a higher stat bonus.

      For core hunters, they usually look at the monsters they can easily kill at the same time dropping the cores they need (be it on field or elite dungeon). This allows them to AFK farm and grind with party.

      Hope this helps 🙂 Enjoy the grind.

      • ckihm
        November 27, 2017 at 7:15 pm

        I think I could use some more guidance on which cores to start farming first then. How do you recommend I think about that?

        • DK
          November 29, 2017 at 5:05 am

          An in-depth Character guide is in the works and will be published next week. It includes the cores you need to farm at your current level. Please look forward to it! 🙂

  • ChangaChanga

    Does the core drop rate go down the bigger the difference in level between me and the mob?

    • DK
      December 14, 2017 at 6:57 pm

      Not much of an effect on core drops but for others, yes (quest scrolls, equipment, etc.). Example: I’m currently level 120 and decided to farm level 50 monsters, I still get a good amount of cores except for lvl 50 quest scrolls. 🙂

  • NastyOh
    January 2, 2018 at 11:16 pm

    I been reading that the Elite Dungeon monsters don’t drop CODEX if you outlevel them, is this true at 120?

    hello and thank you for the guide!can you add the after patch codex please?(120-180 lvl codex)
    that will be awesome!!!!

    • DK
      February 14, 2018 at 6:37 am

      Actually this already includes up to 180 patch but some have incomplete details. We will complete and update this guide with more information so stay tuned 🙂 Thanks a lot

    Very well done. This is a really thorough work!

    I just disagree with “these things take ages to farm” (written in the email that brought me here)… here’s why: you can find summon battles in the “public” chat tab and join them. If you’re in luck, the party leader will do more than 1 summon, rather 3-4 in a row. Sometimes the drop rate is so high that cores drop without fighting… but also adena and soul crystals (usually A-grade).

    Personally, there’s no other way to farm successfully, and without caring about respawn time.

    • DK
      February 22, 2018 at 1:18 pm

      Summon Stones and Core Potions are game changer! It will still need your effort but not as tedious as before 🙂

  • LMP
    March 24, 2018 at 12:47 pm

    Try having clan leader pop a core buff and using your personal core potion. You will be collecting in excess of 300 cores per stone.

  • Jynks

    I am curious – why do you feel Accuracy and Resilience as two of the most important stats for Treasure Hunter? Wouldn’t Crit Rate, for example, be more important than either of those? Why isn’t PDEF/MDEF more important than Resilience?

    Thank you for all the great guides!

    Is this list and the bot ever going to get updated with Slaughter, Emperor Roc, and Keep of Catastrophe cores?

    Question: when can we expect an update to the bot? Is there some way for the community to help out with this?

  • December 24, 2018 at 8:35 pm
