In Star Resonance season 2, the devs massively overhauled the lifeskill system. Here I'll create a summary of EXP efficiency for the best gathering nodes in the game as well as a breakdown of the best bang for your buck when it comes to buying training materials. You can see the full version in the spreadsheet linked here: https://docs.google.com/spreadsheets/d/1hDLIeR0YxzxVtJBqL2ibJnUDvCLH33IQkAjE5c1w3ck/edit?usp=sharing

I'll give you additional information so you're better equipped to create your own, personalized plan based on which skills you want to rank. First, I'll cover general information, then I'll go through each skill individually. Let's get into it.
General Info
The biggest change in Season 2 is that crafts now give EXP based on their rank instead of every craft giving 2 EXP.
Common crafts give 2
Uncommon gives 4
Rare gives 10
Epic gives 40
Legendary gives 100.
On top of this change, they roughly tripled the base amount of experience needed per level. It took 160,000 EXP to reach lvl 50, but getting from there to lvl 60 will take another 200k. They also removed the weekly Life Skill quests and instead offer 200 Life Skill EXP books for sale weekly in the Honor Shop. Each book gives 50 EXP for a total of 10,000 EXP. Season 2 lasts 5 months so we'll get about enough EXP to rank 1 skill to 60 using those.
Using Focus now gives EXP equal to 12 times the cost of the craft, so you can get 3 more skills to 60 using that, assuming they started at lvl 50. If you burn all the Focus potions you get from your guild's weekly grocery shop, you can raise another. That leaves just 1 crafting skill unaccounted for so there's no need to stress unless you plan to use Focus for something other than just training or are trying to stockpile books or potions. I repeat, while I am giving you this information so that you can grind efficiently, you do not have to grind unless you want to.
Alright. Now for the fun part. Math.
The moment I realized no one does Life Skills was when these massive changes dropped and none of the news had ever made it out of the CN server. Anyway, welcome to another video about a niche topic in a niche game with niche applications.

I hope not... That makes no sense... Guess I'll have to run a few on base the next few days to check myself
