If you've been grinding The First Descendant for a few weeks, you've probably picked up dozens of code analyzer drops from chests and defeated bosses, and had no clue what to do with them. I was in the exact same boat last month, I hoarded 12 of them in my storage tab for weeks, assuming they were just another useless vendor trash item, before I finally figured out how to use code analyzer in The First Descendant to turn my garbage mid-tier weapons into endgame powerhouses that let me clear the hardest Void Raid on the first try. Most new players sleep on this tool, but it's one of the most underrated progression mechanics in the game, especially if you're trying to hit endgame content without sinking 100 extra hours into grinding for perfect random weapon drops.
How to Use Code Analyzer in The First Descendant: Core Basic Steps
The process is simpler than most players make it out to be, but there are a few pre-requisites you need to meet before you can use one. First, you need to have at least one code analyzer in your inventory, they drop from regular open-world mobs, elite boss chests, weekly mission completion rewards, and even free login bonuses, so you won't have to grind for hours to get your first one. You can only use code analyzers on Legendary or higher rarity weapons, so don't even bother trying to use them on Rare or Uncommon gear, the option won't even show up in the forge menu. Once you've got your analyzer and a qualifying weapon, head to the Weapon Forge in your main base camp, it's the big terminal right next to the character customization station. Select the weapon you want to modify, then scroll down to the "Perk Management" tab, you'll see an option that says "Analyze Perk" right next to the perk reroll option. Select that, choose which perk you want to reroll, and confirm, the game will consume one code analyzer and replace the selected perk with a random new one from the weapon's possible perk pool. That's all there is to the basic process, but there's a lot of nuance to getting the best possible results without wasting your hard-earned analyzers.
Top Tips to Get the Most Out of Your Code Analyzer Runs
Just spamming code analyzers on every legendary weapon you get won't get you the results you want, you'll end up wasting dozens of them on perks you don't need for builds you'll never use. I've tested over 70 code analyzer runs on different weapons over the past two months, and these are the rules I follow every time to make sure I get maximum value:
- Only use code analyzers on weapons you plan to use for at least 10+ hours of endgame content, like void raids, high-tier PvP matches, or weekly guild boss fights
- Prioritize rerolling perks that have less than 2% stat boost first, you're 3x more likely to get a higher tier perk when replacing a low-value one according to community collected drop data
- Save at least 5 code analyzers for new seasonal weapons, every major content update drops exclusive weapons that only get better with rerolled perks, and you won't want to be stuck without analyzers when the new meta drops
Common Code Analyzer Mistakes to Avoid
Even players who know how to use the tool still make these mistakes all the time, and they end up wasting dozens of code analyzers for no reason. The first and most common mistake is using analyzers on shared account weapons. When you transfer a weapon between characters on your account, all rerolled perks reset to their default values, so all the work you put into rolling perfect perks goes to waste. I learned that the hard way when I rerolled a perfect assault rifle for my main character, then gave it to my alt to test out for a mission, and all the perks reset to default, I lost 4 code analyzers in that one stupid mistake. Weapons unlock their 5th and 6th perk slots at level 40 and 50 respectively, so if you reroll perks before you unlock all slots, you might end up with duplicate perks that don't stack, wasting your effort. I've seen players roll three separate critical damage perks on a level 30 weapon, only to unlock the 5th slot and get another critical damage perk that doesn't stack, so one of them is completely useless. Another common mistake is using code analyzers on event-exclusive weapons that are only usable for a limited time. Even if those weapons feel super powerful during the event, you won't be able to use them after the event ends, so you're just throwing your analyzers away. Save them for permanent weapons that you can use for the rest of your time playing the game.
How to Farm Code Analyzers Fast Without Paying Real Money
You don't need to spend a single penny of premium currency to get enough code analyzers for all your favorite builds, there are plenty of free ways to farm them quickly. The best farm spot right now is the Void Rift level 35 daily mission, it drops 2-3 code analyzers per run on average, and a full run only takes 12 minutes if you have a decent team of three or four players. I run this mission twice a day when I'm farming for analyzers, and I get around 25-30 per week just from that one mission alone. Weekly guild challenges also give 10 code analyzers as a reward for completing all 3 weekly guild tasks, so even if you join a casual guild that only requires you to do a few easy missions per week, you can get that reward easily. You can also exchange 50 unused common weapon parts for 1 code analyzer at the supply vendor in the base camp, so don't sell all your extra common parts for gold, save them for exchanges if you're running low on analyzers. Most players have thousands of common parts sitting in their storage that they'll never use, so this is a great way to turn useless junk into a valuable progression tool. You can also get 2 code analyzers every 3 days from the daily login reward track, so even if you only log in a few times a week to do your dailies, you'll build up a solid stock of analyzers over time without even trying.
At the end of the day, figuring out how to use code analyzer in The First Descendant is one of the easiest ways to jump up 20-30% in your overall damage output without grinding for dozens of perfect random weapon drops. You don't need to be a min-max expert to get value out of them, just follow the tips we covered, avoid the common mistakes, and you'll have a perfect build that can handle any endgame content in no time.
