For comparison, the Welkin pass gets you 2,700 Primogems a month plus 300 Crystals immediately, which is nearly triple the value in terms of pure Primogems.

At 50 Primogems a refresh, that's 1,050 Primogems worth of Resin. If we use the initial Resin refill as a reference and assume that 60 Resin is worth 50 Primogems, then the 1,260 monthly Resin that this daily pass allegedly gets you would be worth about 21 refreshes. The maximum six daily refills costs 800 Primogems, which is about $10 worth of the premium Crystals that can be converted to Primogems. The first refill costs 50 Primogems but the cost increases with subsequent refills. Each day, players can trade Primogems for 60 additional Resin up to six times. It's worth noting that Genshin Impact technically already sells Original Resin via Primogem refills.
