If you can’t specialize yet, it’s because you don’t have enough points in the skill. Fitness, Style, Shooting, and Charisma are leveled by performing successful actions in the in-game world and exiting the raid alive. Medicine, Gunsmith, and Cooking are leveled by reading Skill Books or crafting in the specific discipline.

ZERO Sievert Top Build

If you’re wondering what skills you should invest in, it really depends on what goals you have for your playthrough. However, we do have a few recommendations. 

The best specializations are:

  • Mule: This ends up paying dividends because you don’t have to sacrifice mobility for a larger bag. Increasing carrying capacity will enable you to scoop up more high-value items during your raids.
  • Stealth: If you’re tired of constantly dying, Stealth will help you a lot. You can go in the range of enemies, back up before they see you and snipe them at range. If you get ambushed and die often, then spec into Stealth.
  • Sniper: This Specialization is a toss-up. If you snipe, the increased damage buff in Sniper can’t be beaten. However, Operator and Fast Hands are also very viable if you like to get down and dirty in the battle.
  • Charm: As you get deeper into the late game, you will start bankrupting the Vendor at your base. While the other Specializations, Storage and Workaholic, are good, they lose usefulness later in the game you get.
  • Pharmacist: Being able to craft your own Injectors will save you money in the long run.
  • Modder: You will be modding your weapons in the late-game, so Modder is the Specialization to get.
  • Chef: Again, Chef will save you a lot of money in the long run–so it should be invested in.

Keep in mind this build is just a suggestion. You should play with what you enjoy the most and shift the builds around to fit your playstyle.
