The World Tree Tower (also known as the Memory of Yggdrasil) is a game mode that is connected to the Ragnarok storyline. Upon completing Chapter 1 [Chapter 22] of the aforementioned storyline, it can be accessed by going to the “Battle” screen and finding the mode in the bottom right of the selection, second from the bottom.
The Memory of Yggdrasil is divided into three segments in this order:
- Memory of the Earth
- Memory of the Heavens
- Memory of the Nether
Each stage is subsequently more difficult than the last. For a guide on the Memory of the Nether, commonly noted as the hardest of them all, click here.
To enter each stage, it requires one Rune which is a ticket used as the stamina for this mode. These can not be replenished through any items and can only be gained by waiting for them to replenish over time. You are allowed to hold up to 10 at any time. You gain one Rune every 12 hours.
Each Memory drops its own version of “Memory Fragments”, which are used in the exchange shop. For example, all of the Memory of the Heavens stages will drop Heavens Memory Fragments, which can be used in the “Heavens” tab within the exchange shop.
All of the items available within each shop refresh once per week at the start of each week (Monday, 12:00 AM PDT). Therefore, it is recommended that you prioritize a specific memory per week so you can get the items you want. Items within the exchange shop have a set exchange limit.
Since each stage takes the same amount of Runes, it is recommended to always grind the Fifth Memory of each stage for maximum rewards with skip tickets.
