ZED ZONE skill tree and attributes

Your character grows on two tracks: three attributes that rise as you use them, and a skill tree split into Melee, Ranged, Physical and Technology. Here is how points are earned and what each branch gives.

The three attributes

Since the May 2026 update the old six stats are merged into Strength, Agility and Constitution. Official Constitution and health-regeneration traits also speed up the healing of injured limbs. Official

How you get attribute points

• Levelling up. Points still come with levels. Official
• Doing the thing. Attributes also gain experience from use. Players describe Strength rising from melee hits, and getting hit training toughness. Players report Since Beta 0.9.99.8.15 attribute experience comes at half the old rate, and riding a bicycle trains Strength. Official
• Serums. The Lizard Serum, a guaranteed drop from the Giant Mutant Lizard, permanently grants 1 attribute point, up to 10 times per character, a limit shared with the Enhancement Serum. Official Enhancement Serums were made rarer in supermarkets in October 2026. Official
• Skill nodes. Some skill tree nodes grant perks and attribute points. Official One player reports a cap of about 10 points per stat from use and up to 20 more through Doses in the tree. Unverified

ZED ZONE skill tree branches

The skill tree was rebuilt in Beta 0.9.99.8.15 with more than 30 new skills. Skills learned in older saves were kept and only moved. Official Auto turret skills were shown as “Coming Soon” then and unlocked with 1.0. Official

Roll Distance was buffed in Beta 0.9.99.9.7 to +35%, +65% and +100% at levels 1, 2 and 3. Bolt Penetration and Arrow Penetration can be switched off if you do not want arrows passing through. Official

Red, Green and Blue Doses

The three Doses are items (IDs 250, 251 and 252 in the developer’s table). Official Since Beta 0.9.99.9.1, using one opens the skill tree instead of drinking it, so you no longer waste one by mistake. Official Look them up in the item ID list.

Character creation: what matters later

The May 2026 update added 12 starting perks across the three attribute paths; some exclude each other. Official Crossbow Power and Crossbow Reload skills and two crossbow traits were added to character creation in Beta 0.9.97. Official

Players who reached the late game recommend stamina skills first, and say melee only shines once you have the skills that heal or buff on kills. Mechanical crossbows stay useful late because they load several bolts and need no stamina to draw. Players report

Your character is saved apart from the world since Beta 0.9.99.9.7, so skills, gear and backpack carry into other maps and into co-op. Official

How skill tree nodes unlock

Many building and crafting nodes are researched by bringing the required items, which are returned afterwards (the workbench took a stone axe and stone hammer in a 2026 run). video, Oct 2026 Skill progress itself is fed by the Doses, which are made from mutant parts you butcher from the infected. video The developer’s item table lists those parts: mutant tissue (1050), mutant heart (1051), plant-mutated tissue (1052) and mutant nervous tissue (1053). Official Since Beta 0.9.99.9.7 ordinary zombies drop slightly more Mutant Tissue. Official

Traits seen at character creation in 1.0

A 1.0 video read out the trait list while building a character with a fixed point budget (17 points in that run). 1.0 video Names as shown:

The same player noted the masteries are now a real choice: you can no longer take all of them. Creation also sets starting skill levels such as stealth, lock picking, reload, aiming, HP regain, stamina gain and max HP. 1.0 video Older guides from 2023 describe six attributes and a different tree; they no longer match.
