Stellar Jades vs Oneiric Shards
In Honkai: Star Rail, Oneiric Shards convert into Stellar Jades, which you spend on warp banners. Planning around the pity system is the real key to value.
Banner Strategy
1.Track your pity counter and guarantee status
2.Top up before a limited banner you actually want
3.Prefer the 50/50 for new characters
4.Save for reruns you missed
