Genshin Impact's weapon variety is wide and ever-growing, bending to fit into new metas or potential team comps. Paimon's Bargain Shop, however, has weapons that are good in almost any scenario. Weapons that can stand the test of time are far more valuable in the long-run in the event that meta changes or certain niche weapons die out. The Royal and Blackcliff lines offered by the store work well with several staple characters.
