Poe Genesis Tree Calculator: How It Works

The Poe Genesis Tree Calculator works out the total passive skill points a Path of Exile character can allocate at a given level, factoring in the points earned from quest rewards and the passive point books in the Genesis expansion. You enter your character level and the number of Genesis passive books you have completed, and it returns the total number of passive points available. This is a planning tool for build theorycrafting, not an official game feature.

Formula

The calculator uses a simple linear formula for leveling points, plus a fixed number of quest reward points. The total is:

Total Points = 22 + floor((Level – 1) / 3) + Books

• Level – your character’s current level (1–100).
• Books – number of Genesis passive books you have consumed (each gives 1 point).
• floor() – rounds down to the nearest whole number.
• 22 – the assumed total passive points from all main story quest rewards in the current game version.

For example, at level 90 with 0 books, the formula gives 22 + floor(89/3) = 22 + 29 = 51 points. The game awards one passive point every three levels starting at level 2, so you get points at levels 2, 5, 8, 11, and so on.

Worked Example

Using the default values from the calculator (Level = 90, Books = 0):

1. Subtract 1 from the level: 90 – 1 = 89.
2. Divide by 3: 89 / 3 = 29.666…
3. Round down: floor(29.666) = 29.
4. Add the quest reward points: 22 + 29 = 51.
5. Add the Genesis books: 51 + 0 = 51.

So the calculator shows 51 total passive points. If you had completed 2 Genesis books, it would show 53.

Background: How Passive Points Work in PoE

In Path of Exile, every character earns passive skill points as they level up. The base game grants one point every three levels, starting at level 2, so by level 100 you have 33 points from leveling. On top of that, completing certain main story quests rewards a total of 22 points (in the current 3.x version). The Genesis expansion, introduced later, added a set of passive books that grant an extra point each, but they are limited in number and are not tied to leveling.

The calculator assumes the standard quest reward total of 22. If you have not completed all main quests, your actual available points will be lower. The Genesis books are a separate, optional source that you can add to the calculation.

How to Use the Calculator

To get an accurate number for your build, follow these steps:

• Enter your current character level (1–100).
• Enter how many Genesis passive books you have already consumed (0–10, but check the current league limit).
• The calculator shows the total points, plus a breakdown of leveling points and quest points.

Use the result to plan your passive tree: subtract the points you need for travel nodes and key keystones, and see how many points remain for life, damage, or utility.

Common Mistakes and Misconceptions

One frequent error is forgetting that quest rewards are not automatic – you must actually complete the quests and click the reward. Another is assuming the Genesis books are unlimited; they are a one-time resource per league. Also, the formula assumes you have completed every main story quest that gives a passive point. If you skipped side quests or the campaign, your total will be lower.

Another misconception is that the leveling point formula is “one point every three levels” without the floor function. At level 3, you have only 1 point (from level 2), not 1.0 from 3/3. The floor handles that correctly.

Limitations of the Formula

The formula is accurate for the base game and the Genesis books, but it does not account for:

• Bandit quest choices that give a passive point instead of a skill point (the calculator assumes you took the point).
• Any future patches that change the number of quest rewards.
• Special league mechanics that might grant extra points (e.g., some events).
• The exact number of Genesis books available – it varies by league and whether you have access to the expansion.

Always double-check the current game version’s quest reward total, as it has changed in past patches.

Frequently Asked Questions

How many passive points do you get from leveling in PoE?

You get one point every three levels, starting at level 2, so by level 100 you have 33 points from leveling alone. The formula is floor((level – 1) / 3).

How many passive points from quests in the current version?

As of the current 3.x patch, completing all main story quests that reward passive points gives a total of 22 points. This has changed in the past, so always verify with the latest patch notes.

What are Genesis passive books and how many are there?

Genesis passive books are items that grant one passive skill point each when used. They are a limited resource introduced with the Genesis expansion. The exact number available per league is not fixed in the base formula; check the league’s content for the current total.

Does the calculator include bandit quest choices?

No, it assumes you took the passive point reward from bandit quests. If you helped a bandit instead, you lose that point, so subtract it from the total.

Can I use this calculator for a character below level 2?

Yes, but the leveling points will be 0, and only quest rewards and books apply. At level 1, the formula gives 22 + 0 + books, which is the points from quests only.

Why does the calculator show 51 points at level 90?

Because 22 quest points + 29 leveling points (floor(89/3)) = 51. That matches the standard total for a character who completed all main quests and no Genesis books.
