Atlantica Online – Spoilers – Hidden Repositorium

This Event has reoccurred in the past when Nexon was the Publisher.
There’s a possibility we won’t get the Event and that’s why this is a Spoiler.
“Hidden Repositorium [Japan]: 17th – 31st Aug 2017.”
“Collect event tokens and claim Legion Mercenaries.”

Since we’ve recently experienced a half decent Event from Valofe this month, why not be on the positive side this time around and hope for the best for this upcoming month. Japan is starting their Hidden Repositorium on the 17th of August and usually (knock-on-wood) when Atlantica JP has an Event, so do NA and EU.

Alright, next is to get to the actual dungeon (how it has worked/been in the past).
Bear in mind that much is likely to change and just as much is likely to be the same.

Hidden Repositorium

You can acquire up to 2 Hidden Repositorium Keys per day. It is an instance dungeon and allows you to take 5 mercenaries (Main+5). The objective is to kill as many treasure chests as possible within 10 minutes.

  • It is highly recommended to bring multi-hitters:
    • Axe / Cannon / Dual Sword / Gun / Power Saw
  • and/or have AoE spells/procs:
    • Arms of Atlantis (magic)
    • Ancient Minotaur (mount)
    • Blazing Earth (magic)
    • Chione’s Fury (magic)
    • Green Dragon Glaive (magic)
    • Incarnation of Noble Archangel (mount)
    • Legendary Phoenix (mount)
    • Sage Sword Excalibur (magic)
    • Waltz of the Blade (magic)
    • War Cry (magic)
    • I could go on… but the point is made

The player obtains [Event] Treasure Chests according to their level for each chest that they successfully kill (this part is highly likely to vary). After leaving Hidden Repositorium, the player will have to wait 4 hours until they are able to proceed again with their second key of the day. As always, the timer display will not accurately show the cool-down of the dungeon.
