Re: Aegis Thousand Year War - DMM Online Game
From what I can make out, it seems that the Legendary Ticket and Time Fairy will be added to the Trading Post in exchange for Rainbow Crystals. You will be able to exchange for three of each every month, but after each exchange, the price will go up. It will them reset on the first of the next month, at 4am Japan time.
I think I saw something as well about a limited gacha for Imperial units. I should have a closer look at that.
Edit: For the second half of the Third Anniversary Campaign, there will be a Imperial Premium Summoning where you can summon new Imperial units. The pair pictured are the Black Princess Angeline and the Black Swordmaster Jekurinde (I have no idea how to romanise her name. Jeklinde?). 多数 makes it sound like there will be a lot of new units. They will only be available in this summoning, but it will return at fixed intervals.
