Every upgrade, exact skill point costs, optimal spending order — and how to earn the Pink Halo. Researched February 2026.
The Skill Tree is Tower of Hell’s permanent progression system — a set of upgrades that enhance your gears’ power, duration, range and capability. Unlike gears themselves (which you repurchase every round), skill tree upgrades are permanent once unlocked and persist across all sessions.
There are 5 gear branches, one for each shop gear that can be upgraded: Gravity Coil, Speed Coil, Fusion Coil, Hook (Grappling Hook), and Trowel. Each branch has 4 upgrades that must be purchased in order — you cannot skip ahead. The Hourglass is the only shop gear with no skill tree branch.
Maxing every single upgrade in all 5 branches requires exactly 80 skill points, which means reaching level 80. Completing the full tree unlocks the Maxed badge and the exclusive Pink Halo.
You can only use one active skill per branch at a time — green outline means active, blue outline means unlocked but inactive. Switch between unlocked skills anytime by clicking the blue-outlined skill (and re-equipping your gear). Upgrades are permanent; you cannot lose them. Skill Reset costs 50 Robux if you want to reallocate points.
The original Skill Tree was added December 24, 2019 and revamped on February 20, 2020. Players used to receive multiple skill points per level before the revamp standardized it to exactly 1 skill point per level.
Every time you level up in Tower of Hell, you earn exactly 1 skill point. Leveling up requires XP, which is earned by completing sections. XP and coins are always equal — 1 coin = 1 XP.
XP requirements increase linearly each level. The formula is: XP needed to reach level X = 100 × X. So level 1 needs 100 XP, level 2 needs 200 more XP (300 total), level 3 needs 300 more XP (600 total), and so on.
| Level | XP Needed (That Level) | Cumulative XP | Noob Tower Wins | Pro Tower Wins |
|---|---|---|---|---|
| 1 | 100 | 100 | 1 | — |
| 5 | 500 | 1,500 | 15 | 6 |
| 10 | 1,000 | 5,500 | 55 | 22 |
| 20 | 2,000 | 21,000 | 210 | 84 |
| 40 | 4,000 | 82,000 | 820 | 328 |
| 60 | 6,000 | 183,000 | 1,830 | 732 |
| 80 ???? | 8,000 | 324,000 | 3,240 | 1,296 |
You can also earn partial XP by making it partway through a tower. The XP formula for completing m out of n sections is floor(MaxXP × (m/n)²). This means reaching the top earns 100% XP, reaching halfway earns only 25%.
Leaving a server mid-round grants zero XP, even if you were partway through. You must stay until the round ends to receive XP. Also, XP cannot be earned in THE Tower of Hell (/ttoh) — only in normal and pro servers.
Use Pro Tower servers — completing one pro tower gives 250 XP vs 100 for noob tower, making them 2.5× more efficient per win. Speed up the timer by reaching the top (doubles XP per hour). Set /setlength 6–8 in private servers for consistent, achievable runs. Pro Tower wins to max: only 1,296 — compared to 3,240 noob tower wins.
Five gears can be upgraded through the skill tree. Each has its own branch of 4 upgrades costing a total of 14–16 skill points per branch. All 5 branches together total 80 skill points.
The Gravity Coil branch is the highest priority for most players. The gravity reduction upgrades make sections noticeably more forgiving, and the Double Jump upgrade at the end fundamentally changes how you navigate the tower — allowing you to correct mistakes mid-air.
If you unlock Double Jump in the Gravity Coil skill tree AND buy the Double Jump Mutator (100 coins), you get a triple jump. You get: first jump → skill tree second jump → mutator third jump. This combination can trivialize many of the hardest sections in the game.
The Speed Coil branch focuses on increasing your movement speed and jump power. While speed sounds helpful, most sections require precision rather than speed — these upgrades are best for players who are comfortable with the base game and want extra completion speed.
At 200% speed (Speed Increase III), sections with thin 1–2 stud platforms, headhitters, or conveyors can be extremely punishing. If you are struggling with precision sections, consider staying at Speed Increase I or II until your general platforming improves. Speed is a multiplier of skill — it makes good players faster and bad players fall more.
The Fusion Coil combines gravity and speed effects. Its skill tree branch mirrors the Gravity Coil’s gravity reduction upgrades (same percentages: 45% → 55% → 60%), but applies them to the Fusion Coil instead. This is a great second branch for Gravity Coil players who want a combined upgrade.
The Hook (Grappling Hook) branch extends your reach and increases swing speed — two upgrades that exponentially expand the number of surfaces you can attach to. Even a small range increase can open up entirely new skip routes and recovery lines that were out of reach before.
Advanced players use a hook-jump technique: hold Jump while airborne and hook a surface — you float briefly before the hook pulls you, creating a short hover that functions as a limited second jump. This works at any range upgrade level but is most effective with max swing speed.
The Trowel branch increases block size and unlocks truss placement — a fundamentally different type of placed structure. While the Trowel is often overlooked at high levels, maxing its skill tree makes it a genuinely strong recovery tool, especially on sections with large vertical gaps.
With only 1 skill point per level, every decision matters — especially in the first 20 levels. This optimized path maximizes your effectiveness as fast as possible, based on community consensus and February 2026 meta.
The single best skill point you will spend. For only 1 SP you get noticeably higher jumps and slower falls — immediately impacting every section you play. No other upgrade in the entire tree offers this return at this cost. Buy on your first level-up without question.
Save your next 3 skill points (levels 2, 3, 4) for the second gravity reduction tier. At 55% gravity reduction the coil starts to feel genuinely powerful and comfortable. Many difficult jumps that seemed impossible now have reasonable landing windows. This is where the Gravity Coil becomes your standard gear.
While saving up for the expensive Gravity Reduction III, spend one point on Hook Range I. For just 1 SP your hook reaches to 90 studs — the first range upgrade alone opens skip routes and makes hook recovery far more reliable. Only do this if you own the Hook gear.
This is the biggest early investment — 8 points saved across levels 6–13. The maximum 60% gravity reduction is the gateway to the Double Jump. It’s expensive but essential. During this phase you can optionally grab Hook Range II (3 SP) if you frequently use the hook, but prioritize getting to Double Jump as fast as possible.
After maxing the Gravity Coil branch the Double Jump unlocks. This single upgrade changes how the entire game feels — missed jumps can be corrected mid-air, gaps you were unsure of become confident, and many hard sections drop 1–2 difficulty tiers in your experience. The first major skill tree milestone.
With Double Jump secured, spend points on Hook upgrades for versatility. Range II (120 studs) followed by Swing Speed I covers almost all skip routes discussed in community guides. This phase transitions you from “surviving” to “actively routing” through sections.
Max the Fusion Coil branch (14 SP total: 1+3+8+tier 4). Since it mirrors Gravity Coil upgrades, you already understand how each upgrade feels. The Fusion Coil becomes your best gear for fast runs requiring both speed and jump height simultaneously.
Finish the Hook branch (Swing Speed II, 4 SP) and work through the Trowel branch (Block Size I, II, then Truss Placement — 10 SP total). These upgrades are powerful but situational compared to the gravity/hook upgrades you’ve already unlocked.
The Speed Coil branch is saved for last. Its upgrades are the most situational and potentially hazardous for less experienced players. Spending 16 SP here is entirely about completing the tree for the Pink Halo and Maxed badge. You’ll have plenty of skill and confidence by level 50+ to handle max speed safely.
Gravity I (1) → Gravity II (3) → Hook Range I (1) → Gravity III (8) → Double Jump (1 total for Gravity Coil) → Hook Range II + Swing I (7) → Fusion Coil full (14) → Trowel full (10) → Hook Swing II (4) → Speed Coil full (16) = 80 SP = Pink Halo
Maxing all 80 skill points across all 5 branches rewards you with the Maxed badge and the iconic Pink Halo — one of the six base halos in Tower of Hell and a mark of significant investment in the game.
Play exclusively on Pro Tower servers with Speed Coil + Low Gravity mutator (130 coins). Complete towers consistently. Speed up the timer by reaching the top every round — this doubles XP earnings per hour. At peak efficiency you can reach level 80 in roughly 130–150 hours of active play.
Tower of Hell offers a Skill Reset option in the Robux shop for 50 Robux. This refunds all your spent skill points, allowing you to reallocate them from scratch. Here’s everything you need to know before considering a reset.
How do I open the Skill Tree? Click your level number displayed at the bottom of your screen in-game. The skill tree panel will open showing all 5 branches. Blue outline = unlocked but inactive; green outline = currently selected; locked upgrades appear darker.
Can I use multiple skill upgrades from different branches at once? You can only have one active skill per branch at a time. However, you can switch the active skill within a branch at any time by clicking a different unlocked skill. Different branches are completely independent — your Gravity Coil active skill doesn’t affect your Hook active skill.
Do skill tree upgrades apply automatically when I buy the gear? Yes. As long as the upgrade is purchased and active (green outline), it applies automatically whenever you equip that gear. You don’t need to do anything extra. Remember to switch to your preferred active skill if you switched branches.
Does the Double Jump work with the Double Jump Mutator? Yes — and the result is a triple jump. The skill tree gives you a second jump, and the mutator gives you an additional jump, totaling three jumps before touching the ground. This is one of the most powerful movement combinations in the game.
How many total skill points are needed to max the tree? Exactly 80 skill points. This requires reaching level 80. The total XP needed is 324,000, which equals 3,240 noob tower wins or 1,296 pro tower wins from level 0.
What happens after I max all 80 skill points? You receive the Maxed badge and the Pink Halo cosmetic. After that, skill points have no further use — they continue to be earned on level-up but cannot be spent. The level cap is 1,000,000.
Can I skip upgrading lower tiers to get the top upgrade? No. Upgrades are sequential within each branch — you must purchase Gravity Reduction I before Gravity Reduction II, and so on. You cannot skip to Double Jump without first buying all three Gravity Reduction tiers.
Why can’t I upgrade the Hourglass? The Hourglass is intentionally excluded from the skill tree. It already stops time for everyone — upgrading it would make it too powerful and create an unbalanced server-wide advantage. All other 5 shop gears can be upgraded.
Do skill tree upgrades apply in THE Tower of Hell (/ttoh)? The /ttoh command removes gears from the equation (and /ttoh full allows gears). In the standard /ttoh, there are no gears so skill tree upgrades have no effect. In /ttoh full, gears are allowed and your skill tree upgrades do apply normally.
I’m level 20 and forgot to max Gravity Coil first — should I reset? At level 20 you’ve spent 20 SP. If you have at least Gravity Reduction I and II unlocked, continue and save for Gravity Reduction III + Double Jump before spending elsewhere. Only pay for the 50 Robux reset if you’ve heavily invested in Speed Coil without any Gravity Coil upgrades — in that case a reset is worth it.
