Icarus Tech Tree Calculator Guide

The Icarus tech tree calculator is an online tool that lets you plan which talents and blueprints to unlock in the survival game Icarus before you spend skill points. You input your current level, the talents and blueprints you want, and it returns the total points required and whether your planned build fits within the available points. This article explains how these calculators work, how to use them effectively, and what to watch out for.

Formula

The core formula for any Icarus tech tree calculator is simple:

Total points needed = Talent points + Blueprint points

Where:

• Talent points = the sum of all talent point costs for the talents you select.
• Blueprint points = the sum of all blueprint point costs for the blueprints you select.

You also need to know how many points you actually have. In Icarus, you earn one talent point and one blueprint point for each character level you gain, starting at level 1. So at level 30, you have 29 talent points and 29 blueprint points (30 minus 1). The calculator above uses this logic to show if your planned build fits.

Worked Example

Let’s use the default values from the calculator above. You are at level 30, which gives you 29 talent points and 29 blueprint points. You want to spend 50 talent points and 40 blueprint points (perhaps a very ambitious build).

1. Total points needed = 50 + 40 = 90 points.
2. Points available = (30 – 1) + (30 – 1) = 29 + 29 = 58 points.
3. Points left over = 58 – 90 = -32 points.

The calculator shows -32 points left over, meaning you are 32 points short. You would need to reach level 91 to afford that build, which is impossible because the level cap is 60. This example shows why planning is essential.

How Icarus Skill Points Work

Icarus has two separate tech trees: the Talent Tree (character abilities) and the Blueprint Tree (crafting recipes and structures). Each tree uses its own type of point, and you earn one of each per level. You start with zero points at level 1, so at level 60 (the current cap) you have 59 talent points and 59 blueprint points. This is the hard limit for any build. A good calculator will let you input your level and the points you plan to spend, and then tell you if you’ve overspent. Some online calculators also let you click through the actual tree to see the costs visually.

How to Choose a Build

When planning your tech tree, consider your playstyle and the mission type. For example, a solo player might focus on self-sufficiency talents (like faster stamina regen or better harvesting) and blueprints for basic tools and a stone base. A group player might skip some personal talents and instead unlock shared blueprints like the cooking station or the fabricator. Here are some practical steps:

• Decide your primary role: combat, gathering, building, or crafting.
• List the must-have blueprints (e.g., the bow, the stone axe, the mortar and pestle).
• List the must-have talents (e.g., increased melee damage, faster mining).
• Add up the costs for each tree separately.
• Compare against your available points (level – 1).
• Trim the least essential items until you fit within the cap.

Remember that some talents have prerequisites, so you may need to spend points on intermediate talents to reach the ones you want. The same applies to blueprints – you often need to unlock a lower-tier item to access the higher-tier one.

Common Mistakes and Misconceptions

One common mistake is forgetting that you earn points only from leveling, not from any other source. Another is assuming that respeccing is free – in Icarus, you can refund points, but it costs in-game currency (Ren) and the cost increases with your level. A third mistake is ignoring prerequisites. For example, to unlock the Composite Bow blueprint, you must first unlock the Bow and Wooden Bow (or similar). The calculator cannot know those prerequisites unless you include them, so you must manually account for them. Also, some players confuse the two point types – you cannot spend talent points on blueprints or vice versa.

Limitations of a Calculator

Most Icarus tech tree calculators are static – they don’t know the exact tree layout of the latest game version. The game has been updated with new talents and blueprints over time, so a calculator that hasn’t been updated may be missing options. Also, calculators cannot tell you which build is best for a specific mission, because that depends on the mission’s objectives, the environment (e.g., desert vs. arctic), and your skill level. Use the calculator as a planning tool, not as a substitute for in-game experience.

Alternatives to Using a Calculator

If you prefer not to use an external calculator, you can plan your build in-game by opening the tech tree and hovering over each talent/blueprint to see its cost. The game shows you your current points at the top of the screen. You can also use a spreadsheet to track your planned picks. Some players use community-made guides that list recommended builds for each mission type. However, a dedicated calculator is faster if you want to test multiple combinations quickly.

Frequently Asked Questions

Q: How many total talent points can I get in Icarus?
A: At the current level cap of 60, you get 59 talent points and 59 blueprint points (one per level, starting from level 1). This is the absolute maximum for a single character.

Q: Can I reset my tech tree in Icarus?
A: Yes, you can refund points, but it costs Ren (the in-game currency) and the cost scales with your level. It’s cheaper to plan ahead.

Q: Do I need to unlock prerequisites for blueprints?
A: Yes, most blueprints have a prerequisite chain. For example, to unlock the iron tools, you must first unlock the basic stone tools and the smelting tech. The calculator cannot auto-fill these, so you must include them in your plan.

Q: What is the best build for solo players?
A: There is no single “best” build, but solo players often prioritize self-sufficiency: talents that boost stamina, health, and harvesting speed, and blueprints for a water purifier, a cooking pot, and a stone base. Use a calculator to see if your picks fit within your level.

Q: Why does my calculator show a negative number?
A: A negative result means you’ve planned more points than you can earn at your current level. You either need to level up more (if below 60) or cut some items from your build.

Q: Are there any hidden costs in the tech tree?
A: No hidden costs, but remember that some talents have multiple ranks (e.g., rank 1, 2, 3) and each rank costs the same number of points. Also, some blueprints require materials to craft, but those are not tech points – they are in-game resources.
