That being said, the Covenant Summon is the only way to acquire bulk amounts of Silver Transmit Stones and Powder of Knowledge. However, this method will get pretty expensive pretty quickly, and we aren’t talking about in-game currency. Depending on how much of each in-game currency you require, your real-world cash will have to fund your Covenant Summons sooner rather than later.
Rate Up Banner Vs. Covenant Banner
There are tons of reasons why summoning on a rate-up banner is much better than summoning on the Covenant banner.
Are You a Whale?
If you are a whale, then summoning on the Covenant Banner has a lot more value. Lots of Silver Transmit Stones, lots of Powder of Knowledge, and the added chance of acquiring rare Moonlight Heroes are all attainable on the Covenant Banner. Note: Even if you summon a duplicate five-star, you will now receive Covenant and Galaxy coins with which to exchange for the unit of your choice.
