What Is a Ability Tree
In case you’re new to recreation design, consider a ability tree as a branching roadmap of talents. 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The concept got here from tech timber in outdated board video games like Civilization. Nevertheless it was Diablo II that introduced it into video video games in a giant manner. That recreation’s timber gave gamers lively 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 sort of anticipation a very good ability tree creates.
In distinction, I as soon as prototyped a small RPG the place I forgot to incorporate a ability tree. Playtesters mentioned 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 partaking.
Key Takeaways
Ability timber are in every single place in trendy video games. You’ve seen them in Murderer’s Creed, God of Conflict, Spider-Man, and doubtless a dozen RPGs you’ve performed.
At their finest, 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 % injury upgrades that you just click on by way of with out considering.
As a designer, your job is to make ability timber that gamers really care about.
This information will present you how you can do it, from the fundamentals of what a ability tree is, to widespread pitfalls, and sensible ideas for constructing one which gamers will bear in mind.
Why Do Video games Use Ability Bushes
Ability timber aren’t simply there to present gamers one thing to click on on. They serve actual functions in recreation design.
They assist handle complexity. Think about if God of Conflict began with each transfer unlocked. It could be overwhelming. As a substitute, Kratos’s ability tree introduces new combos step by step, protecting gamers engaged with out overloading them.
They create company. In Murderer’s Creed Origins, I centered 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 timber 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 trustworthy—they appear cool. The UI group will get to make flashy icons and themed layouts that reinforce the sport’s world.
Based on the 2023 GDC survey, over 75 % of video games launched that yr used ability timber or one thing related. However right here’s the catch: just a few felt really thrilling.
How Ability Bushes Can Go Improper
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 observed after they earned a brand new ability level.
This occurs in massive video games, too. The Witcher 3’s fight tree is infamous for its boring proportion upgrades. Gamers usually follow fundamental assaults as a result of the tree doesn’t add sufficient significant selection.
One other mistake is making ability timber too linear. If each participant finally ends up with the identical talents, 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 important for fight however should 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 bunch of daggers simply to degree 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 types of ability timber in video games.
Linear timber are easy and good for narrative-heavy video games the place you need extra management over participant development.
Branching timber give gamers extra freedom. Murderer’s Creed Origins allows you to select between stealth, fight, and gadget-focused builds.
Hybrid methods mix timber 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 talents in loopy methods. I as soon as constructed a poison archer from a category meant for magic as a result of I may path throughout the tree. It was clunky however extremely satisfying when it labored.
Examples of Ability Bushes
- Diablo II – The unique branching RPG tree. View on Diablo’s web site
- Path of Exile – An enormous net of passive expertise. View dwell planner
- God of Conflict Ragnarok – Centered timber with high-impact upgrades.
- Monster Hunter World – Weapon improve paths that act as timber.
- Breath of the Wild – A world-sized development system the place exploration unlocks upgrades by way of Spirit Orbs.
Every of those video games makes use of ability timber 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 realized from making, and breaking, ability timber.
Make each improve thrilling. Give gamers new mechanics, not simply small buffs. God of Conflict 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 along 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 stability offense and protection of their builds.
Playtest relentlessly. The primary model of your tree shall be damaged. That’s okay. Simply be certain that gamers can respec, however don’t make it really easy they reset earlier than each combat.
Alternate options to Conventional Ability Bushes
You don’t have to make use of a ability tree simply because “each recreation does.”
- Crimson Useless Redemption 2 – Unlocks talents routinely by way of story development.
- Fallout 76 – Makes use of perk playing cards.
- Monster Hunter World – Bases development on crafting weapons and armor.

Additionally, take note of pacing. Does pausing to assign factors suit your recreation, or does it break immersion? In certainly one of my prototypes, I changed menus with in-world shrines the place gamers earned new talents. Playtesters liked the way it stored them on this planet.
