Arcane Catacombs Quest Guide

1. Start the quest by talking to the Arcane Mistress in Naveska after you completed "Sage's Quest". She will require you to be able to fend off an invasion of monsters in the Church of Naveska. I recommended level for your team is level 60 as the monsters will coome in waves containing of 5 level 50 monsters up to 4 waves.
2. After you defeat the waves talk to the Arcane Mistress again and she will tell you that the Arcane Catacombs have opened up due to the sun and moon aligning in the right position and in order to become an Arcane Spellbreaker you will have to read the scrolls in them.
3. The Arcane Catacombs can only be found in a certain location which is located north of Maelyis and near the western High Seas. To open it you will have to have at least one character in your active party as an Ancient Umbromancer or a Flux Summoner. In order to open it the character has to have the Arcane Bladenecklace accessory on. You will get a message saying the necklace will start glowing if you find the entrance.
4. When you enter the Arcane Catacombs, it is best that you have a character with a tank class like Paladin or Storm Titan or Myriadic Deathknight on as the monsters will be strong and tough to handle. Apply buffs during fights to keep your team alive.
5. The Arcane Catacombs has 5 different areas each with an aura that increases the damage of certain elements so keep an eye out if any of your character's classes are weak to that element and keep them alive.
6. The first area increases damage done by the element of Chaos. The boss is called "The Chaoscrypter" which is a boss that does heavy chaos elemental damage and can inflict certain ailments. Keep your team alive and continue down the path.
7. The second area increases damage done by the element of Fear. The second area is way different then the first area as it is pitch black and you are in an endless space and a small light will indicate where you are. The correct path to get to the boss of that area is west, north, south, south, east, east, north, south. The boss is called "The Nightmare" which is a boss that does heavy fear damage and can inflict sleep and instadeath so pack up a lot of stuff and head back if you need to. (To exit back before you fight the boss just walk to the door you came from and it will take you back to the beginning)
8. The third area increases damage done by the element of Lightning. The third area is a giant area that requires at least one character with a class that absorbs lightning damage. The entrance to the room of the boss is guarded by a lightning barrier that can only be entered if the party leader is using a class that absorbs lightning. The boss is called "The Sparklighter" which is a boss that does heavy lightning damage and can inflict blind and heal itself using lightning based attacks so cast reflect on it.
9. The fourth area increases damage done by the element of Rust. The fourth area is a giant room that can be confusing and tricky if you don't manuever right it will make you mad. You need to find the correct path through the room of sawblades and if you fail the sawblades will damage you with rust damage unless your characters absorb or are immune to rust damage. The boss is called "The Sawblazer" which is a boss that does heavy rust damage and can inflict bleed and brittlebone strike it hard with ash based damage.
10. The fifth and final area increases damage done by the element of Void. The final area is a giant room that holds many portals that lead you to the different areas in the room. Follow this path of portals: East, East, North, South, South, West, North, West, East, South, East. This will lead you the boss in the final crypt area which is called "The Voidplunger" which is a boss that does heavy void damage and can inflict blind and confusion.
11. After defeating the boss of the area, you will enter a cutscene and leave the Arcane Catacombs. When you return to the church, the Arcane Mistress will be attacked by several Aldor Knights and you will enter a fight against them. After defeating the knights, the Arcane Mistress will thank you by replying that she is part of Kellos's forces and has been after the scrolls for the whole time. She will then demand you to give her the scrolls and gets rejected from you she gets mad and attacks. She is the final boss fight of this quest and is a tough boss to handle if you aren't prepared. She has the ability to attack more then once and has extremely powerful spells that do certain elemental damage or are completely devastating.
12. When you defeat her she will vanish into thin air but not after saying that Kellos will have his revenge and destroy the world.
