🔥 Path of Exile Aura Calculator – Plan and Optimize Your Aura Reservation

This PoE Aura Calculator is an interactive tool that helps players calculate the exact amount of mana or life reserved by each aura in a Path of Exile build.
It supports all core reservation skills including auras, heralds, banners, and aspect skills used in endgame builds.
Players can simulate multiple aura setups by combining different skills, support gems, and unique items that affect aura reservation.
The tool reflects current Path of Exile mechanics by applying the correct reservation formula to every selected skill or modifier.
This reservation formula calculates final cost using: Aura Cost × (1 + Reduced Efficiency) ÷ (1 + Increased Efficiency).
Every selected aura uses this formula, ensuring accurate results that align with in-game reservation behavior.

⚙️ How Aura Reservation Works in PoE – And How This Tool Helps

Aura reservation in Path of Exile is affected by passive tree nodes, ascendancy bonuses, support gems, and specific unique items.
This calculator allows players to apply reservation-modifying effects like Enlighten, Arrogance, and Generosity directly to chosen skills.
Each skill selection updates live, allowing you to instantly see how your support gem links alter reservation values.
The tool accounts for gear effects like Essence Worm, which removes the reservation cost of socketed auras entirely.
It also includes items like Prism Guardian, which causes auras to reserve life instead of mana while applying a local efficiency modifier.
Players can include ascendancy nodes such as Supreme Ego, Inspiration, or Sanctuary of Thought, each with unique reservation effects.
Cluster jewels, timeless jewels, and reservation-related notables can also be added to simulate deeper passive tree strategies.

🧪 How to Use the PoE Aura Calculator – Step-by-Step Instructions

Begin by selecting the auras, heralds, banners, or aspects that you plan to use in your character’s build.
Choose which support gems are linked to each aura to reflect how your sockets are configured.
Select any unique items that apply local or global reservation efficiency changes to those auras.
Apply ascendancy effects or passive nodes that increase or reduce mana or life reservation efficiency.
Input your total mana and life pools so the tool can calculate your remaining resources after reservation.
The tool displays live results that show individual reservation per skill, as well as total reserved and remaining values.

📊 What the Results Show – Reservation Costs and Breakdown

Each selected aura shows its exact reservation value based on your current inputs and modifiers.
A clear breakdown shows whether the reservation comes from mana or life, based on item placement and gem links.
The total reservation summary tells you how much of your mana or life pool is used and what remains for active skills.
Color-coded outputs make it easy to identify which skills are the most costly and which are being optimized efficiently.
You can quickly change any input — such as swapping an aura or support gem — and see the new results update instantly.
This makes it easy to compare multiple build configurations and see which setup fits within your resource constraints.
