The last Primogem-hording bit of advice is this: Unless you have more money than you know what to do with, avoid spending Primogems on Wishes for use with Weapon Event Banners. Most newly introduced five-star characters have a signature weapon; a weapon that generally edges out four-star weapons. Unfortunately, earning these potent armaments requires rolling on the Weapon Banner, which has notoriously bad rates for the promotional weapons. Thankfully, this system has improved slightly since Genshin Impact’s launch, but it is still a tremendous money sink no matter how you look at it.
Essentially, you can chart which of the two promotional weapons you want to pull. You’re guaranteed a five-star weapon at 90 Wishes, but you only have a 50 percent chance of getting the weapon you want. If the five-star weapon you earn is not your chosen one, you earn a Fate Point. Once you earn two Fate Points, which is to say you lose the 50/50 twice in a row, your next five-star roll is guaranteed to be the weapon you want. In essence, the worst case scenario is that you need to Wish 270 times on the Weapon Banner to get the gear you want. With Wishes costing you some $2.60 a pop, you’re looking at more than $700 worth of Wishes to get a guaranteed weapon of your choosing. Sure, there’s always a chance that you get it sooner, but the odds are pretty ugly no matter how you look at it. Stay away from the Weapon Banner, especially if you’re going the free-to-play route. You’re never getting those Primogems back.
