Overview

After the collapse of Fortessa Dungeon, the spirits that used to wander in the castle now roam free and made themselves a home in the Netherworld, now empowered by the dark energies spiking, they need to be put to rest.

Fortessa Damage Reductions

• When damaging a boss inside the themed fortessa dungeons: All non single target damage skills are reduced by 90% of their damage and single target skills will deal 50% of their normal reduced damage.
• Inside any fortessa dungeon you deal 70% reduced damage.
• All monsters have 500-600 RES/MRES.
• All monsters are boss protocol outside of damage calculations, however during damage calculations they're considered normal monsters.
• All resistances and damage reductions are capped at 90%.
• inside All monsters have extremely high luk meaning their CRITICAL DEF SHIELD is extremely high.
• Any and all healing from skills is reduced by 50%.
• The following skills are less effective inside any and all fortessa dungeons:
  • Guardian Shield ( HP reduced by / 2 )
  • Rebound Shield ( Reduction reduced by / 2 )

Cooldown

Fortessa Netherworld has a 7 days cooldown ( resets at mondays 00:01 ) or when a certain condition is met. Those conditions are:

1. Finishing all 6 dungeons within a 7 day span will automatically remove the special "cooldown" - The cooldown is not like any normal cooldown, it does not prevent you from entering again. You may enter as many times as you want, however once you have killed 350 monsters of 1 dungeon you're "soft-locked" to this dungeon and your droprate on normal item drops are reduced by 90% - Same case may be said about the boss box.
2. If you have cleared this certain instance previously and you're doing it for another reward of the boss box, your chances are reduced by / 10 - The instance uses the class prevention and therefor does not allow repeated classes to enter with the exception of Cardinal/Arch Bishop - You may edit your party, invite others while the themed dungeon is active - All bosses have a 2b HP shield -- YOU MAY NOT change your class while inside

Walkthrough

Map Walkthrough

At the start of the instance is an Orb of Control. You can use the orb to go directly to the boss, otherwise you can farm the map for its drops.

Boss Mechanics

• Every 30 seconds 2 minion spawns
• Every 15 seconds the boss gets uneasy, during her uneasiness, any damage she takes makes her angrier.
• Once her angriness has reached 100%, she will kill everyone.
• Certain effects happens depending on how much damage she took during this period:
  • If the damage taken exceeds 3% over the past 10 seconds: everyone takes 25% max hp damage.
  • If the damage taken exceeds 4% over the past 10 seconds: everyone takes 40% max hp damage.
  • If the damage taken exceeds 5% over the past 10 seconds: everyone takes 50% max hp damage, and she regenerates 200m of her shield
  • If the damage taken exceeds 6% over the past 10 seconds: everyone takes 60% max hp damage and she regenerates 200m of her shield.
  • If the damage taken exceeds 7% over the past 10 seconds: everyone takes 70% max hp damage and she regenerates 400m of her shield.
  • If the damage taken exceeds 8% over the past 10 seconds: everyone takes 80% max hp damage and she regenerates 600m of her shield.
  • If the damage taken exceeds 9% over the past 10 seconds: everyone takes 90% max hp damage and she regenerates 800m of her shield.
  • If the damage taken exceeds 10% over the past 10 seconds: she kills everyone and she regenerates 1b of her shield.

Special start area of the themed dungeons

At the start of the dungeon you may select to start over on the highest monster kill count of your party members or start over. This means: Example you have 3 players in your party: a killed 5 monsters, b killed 100 monsters, c killed 350 monsters, you could select to start at the kill of 350 and therefor the entire party gets instantly warped to last boss and may only do the last boss now.
