What is a Poe Legion Jewel Calculator?

A poe legion jewel calculator is a specialized tool designed for players of the popular action RPG, Path of Exile. These calculators help players assess the value and power of a “Timeless Jewel.” Timeless Jewels are unique items that, when socketed into the passive skill tree, alter all passive skills within a certain radius. The effects are determined by the jewel’s specific name and a random “seed” number.

This calculator focuses specifically on the Brutal Restraint jewel, which is themed around the Maraketh legion. It evaluates the jewel’s effectiveness by quantifying the total bonuses it provides, such as added Dexterity and powerful effects on Notable passives. By inputting the number of affected passives and the specific bonuses gained, a player can generate a “Power Score” to easily compare different jewels. For more in-depth build planning, check out this guide on Path of Exile builds.

Brutal Restraint Power Score Formula

The calculator uses a weighted formula to generate a “Power Score,” which represents the overall offensive and defensive value provided by the jewel. The calculation is as follows:

Power Score = (Total Dexterity * 2) + (Aura Effect % * 10) + (Onslaught Bonus * 40) + (Frenzy Bonus * 50)

This formula is designed to weigh impactful but conditional bonuses like Onslaught and Frenzy generation higher than raw stats.

Variables Explained

Variable Meaning Unit Typical Range
Total Dexterity The sum of all flat Dexterity gained from small and notable passives. Points 20 – 150
Aura Effect % The percentage increase to the effect of your non-curse auras. Percentage (%) 0% – 24%
Onslaught Bonus A binary value (1 if present, 0 if not) for gaining Onslaught on kill. 0 or 40
Frenzy Bonus A binary value for the chance to gain a Frenzy Charge on kill. 0 or 50
The key variables used in the poe legion jewel calculator.

Practical Examples

Example 1: Ranger Jewel Socket

A player sockets a Brutal Restraint near the Ranger starting area, affecting 12 small passives and 4 notables. The jewel grants “5% increased Dexterity” and “Onslaught on Kill”.

  • Inputs: 12 Small Passives, 4 Notable Passives, Bonus Dex checked, Bonus Onslaught checked.
  • Results:
    • Total Dexterity: (12 * 4) + (4 * 20) = 128 (Note: Notables give 20 Dex)
    • Power Score: (128 * 2) + (0) + (1 * 40) + (0) = 296

Example 2: Shadow Jewel Socket with Aura Effect

A player sockets a jewel in the Shadow area, affecting 8 small passives and 2 notables. It grants “8% increased effect of Non-Curse Auras”. They paid 100 Chaos Orbs for it.

  • Inputs: 8 Small Passives, 2 Notables, Bonus Aura checked, Jewel Cost: 100.
  • Results:
    • Total Dexterity: (8 * 4) + (2 * 20) = 72
    • Power Score: (72 * 2) + (8 * 10) + 0 + 0 = 224
    • Power per Chaos: 2.24

Key Factors That Affect Legion Jewel Value

  • Jewel Seed: The seed number (e.g., 500-8000 for Brutal Restraint) determines the specific bonuses added to notables. No two seeds are alike, making some vastly more valuable.
  • Socket Location: The value of a jewel is highly dependent on where it’s socketed. A jewel that’s mediocre in the Templar area might be god-tier in the Ranger area due to the different notable passives it can affect.
  • Build Synergy: The most important factor is how the jewel’s bonuses align with your character’s build. A jewel granting “+5% increased Dexterity” is extremely valuable for a Dexterity-stacking build.
  • Keystone Transformation: Timeless Jewels transform major Keystone passives into powerful, often build-defining, new ones. The Keystone it grants is determined by the name on the jewel (e.g., Asenath, Balbala).
  • Market Demand: Like any item in a player-driven economy, value is dictated by supply and demand. Knowing which bonuses are currently “meta” is crucial for trading. Efficient PoE currency farming strategies can help you afford top-tier jewels.
  • Point Efficiency: A great jewel provides significant power without requiring the player to spend too many passive points to path to the affected notables.

Frequently Asked Questions (FAQ)

What is the difference between Brutal Restraint, Lethal Pride, and Militant Faith?
They are different types of Timeless Jewels. Brutal Restraint focuses on Dexterity, Lethal Pride on Strength, and Militant Faith on Faith-themed and aura bonuses. Each adds different stats and transforms keystones differently.
Does the number on the jewel matter?
Yes, critically. The number is the “seed” that dictates what bonuses are applied to every notable in its radius. A higher number does not necessarily mean better; it’s just a different seed.
How do I find a good jewel seed?
Players often use third-party tools or the in-game Path of Building Community Fork to search for specific jewel seeds that provide the mods they want on the passives they have allocated.
Can I change the bonuses on a jewel?
Yes, by using a Divine Orb. However, this will re-roll both the seed number and the name (which affects the keystone), so the outcome is completely random.
Where do I get a Brutal Restraint jewel?
Brutal Restraint can drop from the Maraketh legion in the Domain of Timeless Conflict content or be acquired by trading with other players.
Why does the calculator have a ‘Power Score’?
The Power Score is an abstract metric to help you quickly compare two different jewels. Since “value” is subjective and build-dependent, this score provides a standardized baseline for comparison.
Is this poe legion jewel calculator a replacement for Path of Building?
No. This is a quick evaluation tool. Path of Building (PoB) is a comprehensive build planner that can simulate the jewel’s full effect on your character’s stats, which is essential for true min-maxing your Passive skill tree guide.
How important is the ‘Power per Chaos’ metric?
It’s a measure of cost-efficiency. A jewel might have a very high Power Score but cost thousands of Chaos Orbs. A different jewel might offer 90% of the power for only 10% of the cost. This metric helps identify the best value for your budget, a key part of Endgame mapping and gearing.
