7 Days to Die has no locked classes — but its five attributes function exactly like them. Each attribute buffs one group of weapons for headshots and unlocks a unique Mastery at level 6. So “best class” is really “which weapon group and Mastery do you want to commit to”. This guide lays out the five attributes with the wiki’s real numbers, so you pick the one that fits how you actually play.
The shared rule: attributes are weapon groups
Every attribute gives 200% headshot damage to its weapon group at level 1, then +10% headshot and +5% dismember chance per level from 2–8, and +15% headshot and +5% dismember at levels 9–10. The only difference is which weapons count:
| Attribute | Weapons it buffs | Mastery theme |
|---|---|---|
| Perception | Spears, rifles, explosives | Ranged precision and scavenging |
| Strength | Shotguns, clubs, sledgehammers | Melee and mining |
| Fortitude | Fists, machine guns | Survival and health |
| Agility | Bows, handguns, knives | Mobility and archery |
| Intellect | Stun batons, robotic turrets | Tech and crafting |
That table is the whole decision. If you like rifles, you are a Perception build. If you like sledgehammers, you are a Strength build. The Mastery then deepens that identity.
What it costs to max one attribute
Levels are not flat. From level 1 to 10:
- Levels 2–5: 1 skill point each (4 points)
- Levels 6–8: 2 skill points each (6 points)
- Levels 9–10: 3 skill points each (6 points)
That is 16 points to max one attribute, and the Mastery only starts paying at level 6. The practical rule is to commit to one attribute line first rather than spreading points, because depth is what unlocks the strong tiers.
Mastery: what each attribute gives at level 6+
The Mastery is a five-level perk that opens at attribute level 6. Each level is a different bonus, and the numbers decide the pick:
| Attribute | Level 1 | Level 2 | Level 3 | Level 4 | Level 5 |
|---|---|---|---|---|---|
| Strength | Miner’s Mending: injuries heal 100% faster holding a mining tool | Brass Miner: 5% chance of scrap brass when mining ore | Battle Miner: mining tools deal more damage to zombies | Headhunter: +50% dismember chance with clubs/sledgehammers | Adrenaline Berserker: 25% damage resistance for 5s on a kill |
| Perception | Cushion Crawler: harvest dukes and cash from cushioned seating | Salvage Specialist: harvest steel from cars and safes | Vital Wound: spear and rifle hits cause bleeding | Blood Rush: sprinting spear power attacks +25% damage | Long Shot: rifle shots +50% damage |
| Fortitude | Bleed Stopper: kills stop bleeding without a bandage | Antibodies: immune to infection for 2 real hours after recovering | The Dentist: 10% chance of silver/gold teeth from fist kills | Resilience: permanently +50 max health | Unbreakable: permanently +50 more max health |
| Agility | Snare Shot: 40% chance to cripple on a leg hit | Rapid Reload: handguns reload 20% faster | Bleeding Hearts: bows, crossbows and handguns cause bleeding | Spectator’s Grace: deflect the first blow, recharges every 60s | Piercing Precision: full bow shots bypass armor and deal +25% damage |
| Intellect | Master Pilot: vehicles take 20% less damage and use 20% less fuel | Bookworm: +25% chance to find a book, magazine or schematic | Photographic Memory: 50% chance of 2 skill points per magazine | Genius Fury: stun batons charge in 2 hits | Baton Master: +300% shock damage |
Which “class” to pick
- New player / survive longer: Fortitude. Resilience plus Unbreakable is a permanent +100 max HP, the single biggest survivability swing in the tree, and fists plus machine guns are forgiving.
- Ranged sniper: Perception. Long Shot gives rifles +50% damage, and Vital Wound adds bleed.
- Bow or handgun skirmisher: Agility. Piercing Precision lets a full-draw bow bypass armor, and Rapid Reload keeps handguns flowing.
- Tech and crafting: Intellect. Baton Master’s +300% shock damage is the biggest single multiplier, and Bookworm plus Photographic Memory accelerate your whole progression.
- Melee brawler / miner: Strength. Adrenaline Berserker turns kills into damage resistance, and the mining perks feed your base.
The counter-intuitive picks
- Fortitude is secretly a damage-adjacent tree. Its Mastery’s +100 max HP is worth more than most damage perks in a survival game, because it turns a fatal mistake into a wound.
- Intellect’s +300% shock damage is the largest multiplier in the game, but only on stun batons — it is a narrow, huge spike, not a general buff.
- Perception’s Long Shot (+50% rifle damage) is the cleanest ranged upgrade, which is why rifle builds stack Perception even when they take Strength weapons as a backup.
How every perk gates on attribute level
The attribute is not just a damage knob — it is the gate for every perk beneath it. Each perk level demands a specific attribute level, and the wiki’s requirement table shows the pattern:
- Standard perks unlock at attribute 1 / 2 / 3 / 5 / 7.
- Attack-speed perks and Parkour unlock at 2 / 4 / 6 / 8 / 10.
- Each Mastery opens at 6 / 7 / 8 / 9 / 10.
That is why committing matters: a perk you want may sit behind an attribute level you have not reached, and no amount of points in the perk itself will unlock it.
Temporary boosts do not stick
Some drugs and items raise an attribute temporarily, which can satisfy a perk prerequisite early. But the wiki is explicit: when the effect wears off and you no longer meet the requirement, you lose that perk level until you meet it again. A drug can unlock a perk for a single fight; it is not a permanent shortcut.
Why splitting fails
Because maxing one attribute costs 16 points and the Mastery only starts at level 6, spreading points across two attributes leaves both below their strong tiers. The working approach is one weapon line and one crafting line, pushed deep — depth reaches crafting and Mastery tiers that breadth never does.
You can respec, so commit without fear
A respec is available — through a respec item or by enabling it in settings — so committing to one attribute early is not permanent. Use your first build to learn the game, then respec into the line whose weapons you actually enjoy. That removes the usual excuse for spreading points “just in case”; pick a class, play it deep, and switch later if it does not fit.
For how to spend the points themselves, the skill guide covers early-value perks, and the weapon tier list ranks the guns and melee each attribute empowers. The best melee page details the Strength weapons, the survival guide covers health and infection, and how to level fast speeds up the skill points you need.
