Phantasy Star Online 2: New Genesis - All Ryuker Device, Cocoon, Tower, Region Mag, and Battledia Locations | Aelio Region

During your exploration of Aelio in Phantasy Star Online 2: New Genesis, you'll learn that some of the most important locations to find in the region are Ryuker Devices that allow you to teleport across the map, and Cocoons which will earn you valuable Skill Points, essential for increasing your Battle Power. You'll also want to know where Towers are for the same reason. Lastly, Region Mags can net you and your group valuable buffs across a wide area so they're essential to seek out as well. Here we've got a nice map you can cross-check in-game to see which ones you may be missing.

All Retem Region Locations

Since these items are all clearly marked on the World Map and there's only a couple per region (if any), it's easy enough to combine them into a single image here. 

Tip: To check how many locations you've found in a regionopen up the World Map from the main menu, mouse over which region you want to check, and press Tab. This will let you see how many Ryuker devices, Cocoons, etc. you've found in that region (as well as the number of Red Item Containers and Datapods).
Update: In October 2021, New Genesis added Battledia Quests, which are accessed via Trigger Portals located on the map. These are marked as "Battledia" in each region's Exploration list. We've added where to find these in thee Aelio region.

PSO2: New Genesis - All Tower Locations | Aelio Region

Central Aelio

Great Wall

  • Location - Far east of Central City, nearish to the zone boundary leading to Vanford Laboratory Ruins.
  • Objective - This is the most 'dungeon-like' of the towers. You'll have to clear through a few rooms of random assortments of enemies, followed by a mini-boss fight with a Daityl Sword. You'll want a decently high Battle Power for this one.

South Aelio

Aero Runner

  • Location - To the east of the Mt. Piccolt peak in South Aelio
  • Objective - This is a mostly non-combat Tower, meaning it can be an easy 4 Skill Points even if your Battle Power doesn't meet the suggested level. You'll have to do some platforming challenges and avoid some defensive fire.

West Aelio

ALTERS Rush

  • Location - Located at the very north part of West Aelio, directly west of the Altolani Plateau region in North Aelio
  • Objective - One of the more difficult Towers, you'll be facing three mini-bosses, and one of the Side Missions limits how many of the other enemies you're allowed to defeat. A nice challenge for those that want it, but it won't affect your Skill Point reward if you ignore it.

Battledias are training exercises that pit players against combat challenges under a time limit. In order to access these, you'll need to get 5 B-Triggers, which are either dropped from enemies or bought on the Personal Shop. Battledia's can be good sources for items like Gold Primm Armor for Enhancement, or unique augments. Purple Battledias can also earn you Gigas-type drops, since you'll be fighting Gigantix during them.
