I have an idea for Square-Enix to help the Adventurers who are working on their Novus weapon(s):

You know how we can do the repeatable quest to do the Expert roulette daily to get a map, right? And, we can continously spend 800 Myths to buy a map, right? Well, here's my idea:

Since you CAN get an Alexandrite from FATES while wearing your Animus, I think Square-Enix should have it where and FATE that don't require Level Sync should give 1 or 2 Myth Tomes per FATE completion while you have your Animus equipped.

Considering how most DPS roles suffer the long wait time for Duty Finder, the DPS-role person can do FATES while waiting on the Expert roulette to trigger. This will help gain Myth Tomes over time while also having a chance to get an Alexandrite from the FATES.

It will help ease one's struggle to gain the 800 Myth Tomes also if that person don't have much time remaining in their day to way for Duty Finder to queue them into am instance. Think about if you waited 20 minutes and Duty Finder never queued, you gained nothing. At least while farming FATES before you need to log off, you'd gain a few Myth Tomes.
