Multiple outlets explain how players can obtain celestine in Subnautica 2 for crafting purposes. Both guides focus on locating the resource efficiently and then using it to create strontium. Polygon provides direction on where to farm celestine, describing the best approach for repeatedly gathering it. PC Gamer similarly centers on acquiring the rare material, emphasizing that celestine is needed to craft strontium. While the two articles differ in wording and presentation, they align on the overall gameplay goal: celestine is a rare resource that players collect from specific in-game locations, after which it can be processed or used in crafting to produce strontium. Taken together, the sources present celestine as an intermediate ingredient in a crafting chain and frame the main task as locating the resource reliably so players can obtain enough material to craft strontium. No competing claims are presented about alternative methods or different end uses for celestine.
