What Is a Ability Tree
In the event you’re new to recreation design, consider a ability tree as a branching roadmap of skills. Gamers begin on the base and unlock new expertise as they play. Every department results in completely different playstyles.
The concept got here from tech bushes in outdated board video games like Civilization. But it surely was Diablo II that introduced it into video video games in an enormous means. That recreation’s bushes gave gamers energetic and passive expertise, restricted factors to spend, and visible branches that made planning thrilling.
I’ll always remember my first time taking part in Diablo II as a child. I spent hours on boards and even drew my Sorceress’s ability plan on graph paper. Planning the construct was half the enjoyable. Later, in Path of Exile, I spent complete evenings theorycrafting character builds earlier than I ever logged in. That’s the form of anticipation a superb ability tree creates.
In distinction, I as soon as prototyped a small RPG the place I forgot to incorporate a ability tree. Playtesters stated the fight felt static as a result of there was nothing to unlock, no sense of development. Including a tree—even a small one—instantly made the sport extra participating.
Key Takeaways
Ability bushes are in all places in trendy video games. You’ve seen them in Murderer’s Creed, God of Battle, Spider-Man, and possibly a dozen RPGs you’ve performed.
At their greatest, they make you’re feeling highly effective, allow you to form your character to your playstyle, and provide you with thrilling decisions to sit up for.
At their worst, they’re bloated menus of +5 p.c injury upgrades that you simply click on by way of with out considering.
As a designer, your job is to make ability bushes that gamers truly care about.
This information will present you do it, from the fundamentals of what a ability tree is, to widespread pitfalls, and sensible suggestions for constructing one which gamers will bear in mind.
Why Do Video games Use Ability Bushes
Ability bushes aren’t simply there to provide gamers one thing to click on on. They serve actual functions in recreation design.
They assist handle complexity. Think about if God of Battle began with each transfer unlocked. It could be overwhelming. As an alternative, Kratos’s ability tree introduces new combos steadily, conserving gamers engaged with out overloading them.
They create company. In Murderer’s Creed Origins, I targeted my factors on the Hunter and Seer branches. This turned Bayek right into a stealth-focused trickster in my playthrough. However my good friend went all-in on Warrior and have become a tank. These decisions made our video games really feel distinctive.
Ability bushes additionally drive replayability. After I replayed Horizon Zero Daybreak, I attempted a completely completely different construct and it felt like a brand new recreation.
And let’s be sincere—they give the impression of being cool. The UI workforce will get to make flashy icons and themed layouts that reinforce the sport’s world.
In accordance with the 2023 GDC survey, over 75 p.c of video games launched that 12 months used ability bushes or one thing related. However right here’s the catch: only some felt really thrilling.
How Ability Bushes Can Go Mistaken
Let me prevent from the errors I made early in my design profession.
In my first prototype, I crammed in a dozen filler upgrades—small injury boosts and well being buffs—as a result of “that’s what video games do.” However nobody cared about unlocking them. Playtesters barely seen once they earned a brand new ability level.
This occurs in large video games, too. The Witcher 3’s fight tree is infamous for its boring proportion upgrades. Gamers typically stick with primary assaults as a result of the tree doesn’t add sufficient significant selection.
One other mistake is making ability bushes too linear. If each participant finally ends up with the identical skills, it’s not likely a tree—it’s a ladder.
Locking core mechanics behind a tree can also be dangerous. In Sekiro, the Mikiri Counter is crucial for fight however have to be unlocked. This made early recreation fight irritating for gamers who didn’t prioritize it.
Be careful for grindy development. Skyrim inspired gamers to spam craft a whole lot of daggers simply to stage up Smithing. That’s not satisfying development.
Even the interface issues. In Doom Everlasting, pausing the motion to dig by way of a ability menu killed the pacing. Distinction that with Downwell’s fast “select certainly one of three upgrades” between ranges.
The lesson? Each ability tree node must really feel like a reward, not an obligation.
Varieties of Ability Bushes
As you get extra skilled, you’ll discover completely different kinds of ability bushes in video games.
Linear bushes are easy and good for narrative-heavy video games the place you need extra management over participant development.
Branching bushes give gamers extra freedom. Murderer’s Creed Origins enables you to select between stealth, fight, and gadget-focused builds.
Hybrid programs mix bushes with different mechanics. Monster Hunter World ties development to its weapon crafting system, making a pure, in-world “tree” for every weapon.
Then there’s the large net strategy, like Path of Exile. Its huge tree lets gamers mix skills in loopy methods. I as soon as constructed a poison archer from a category meant for magic as a result of I might path throughout the tree. It was clunky however extremely satisfying when it labored.

Every of those video games makes use of ability bushes in several methods, however all of them reinforce the sport’s pacing, world, and mechanics.
Designing Nice Ability Bushes
Right here’s what I’ve discovered from making, and breaking, ability bushes.
Make each improve thrilling. Give gamers new mechanics, not simply small buffs. God of Battle Ragnarok nailed this. Each new node felt impactful, and mods let me tailor my expertise to my type.
Encourage creativity. Bushes ought to permit for bizarre builds and off-meta experiments. Path of Exile’s keystones are nice at this.
Combine development together with your world. In Breath of the Wild, exploration results in Spirit Orbs, which gamers use to improve well being or stamina.
Design a structure that matches your theme. In certainly one of my prototypes, I formed the ability tree like a Yin-Yang image. It mirrored the sport’s aesthetics and impressed gamers to steadiness offense and protection of their builds.
Playtest relentlessly. The primary model of your tree can be damaged. That’s okay. Simply be sure that gamers can respec, however don’t make it really easy they reset earlier than each battle.
Options to Conventional Ability Bushes
You don’t have to make use of a ability tree simply because “each recreation does.”
