Whether or not you should get Light Cones in Honkai Star Rail is something you should have thought about. This question is especially important for free-to-play players, as they have to consider whether to save up their Stellar Jade or Star Rail Passes or spend them. Since they are obtained via Warps, the game’s gacha mechanic, whether or not you get them comes down to luck.
Should F2Ps use light cones?
You can grab Light Cones if you have Passes left over, but most of the time you shouldn’t grab them, especially for free-to-play players. The main reason you shouldn’t grab them early in the game is because it’s better to save your Stellar Jade or passes to grab your favorite characters and build a strong team.
Light Cones are used on characters to increase their base HP, Attack, and Defense, as well as give them a passive ability. In order for this to work, your Light Cone and your character's Path must match. So if your team doesn't have good main DPS, sub-DPS, support, or other roles, Light Cones won't be of much use, even if you have one strong character.
But it's not all bad, for example if you don't see yourself pulling for an upcoming character in the near future and you have a Light Cone that you absolutely want to get, then you can go for it. If you're still unsure, then you can also consider the pity.
