The Golden Land story is permanent, 4500 points recommended

The official announcement states the story is permanent, but the gacha pool is limited-time. Some guides suggest getting at least 4500 points to claim the Mysterious Space Fragment, which will be useful for future banners (seems like a mixed pool). Also, be mindful of the time limit, as unused Golden Energy Crystals will turn into regular Energy Crystals if you want to exchange them for items in the Golden Land shop.
