In cheap PoE 2 Currency, raw power alone does not determine how strong a build feels. What truly separates good builds from great ones is synergy — how well different mechanics interact and multiply each other. This is especially true for Aspect Skills.

Aspect Skills are not just generic buffs. Each one aligns better with certain archetypes, damage types, and playstyles. Choosing the wrong Aspect can feel wasted, while choosing the right one can make a build feel significantly smoother, stronger, and more complete.

In this article, we rank all Aspect Skills based on build synergy, focusing on how naturally they integrate with different playstyles and how much value they add to common archetypes.

What Does “Build Synergy” Mean?

When evaluating synergy, we consider:

  • How many builds benefit from the Aspect

  • How well it scales with popular mechanics

  • Whether it conflicts with common playstyles

  • How impactful it feels relative to reservation cost

An S-tier synergy Aspect should work with almost anything and never feel like a mistake.

S-Tier: Aspect of the Spider (Universal Synergy)

Best for: Every build archetype

Aspect of the Spider has the highest synergy in the entire game. It works with:

  • Hits

  • DOT

  • Minions

  • Totems

  • Traps and mines

This is incredibly rare in Path of Exile, where most mechanics are highly specialized.

Why Spider Has Perfect Synergy

Aspect of the Spider applies an enemy debuff rather than a self-buff. This is the key to its universal synergy.

Enemy debuffs:

  • Scale all damage sources

  • Stack with other modifiers

  • Do not require specific stats

  • Are never wasted

Whether you scale:

  • Attack damage

  • Spell damage

  • Ignite

  • Poison

  • Bleed

  • Minion damage

Spider always increases your effective DPS.

Synergy With Modern Mechanics

Spider synergizes extremely well with:

  • Exposure

  • Curses

  • Wither

  • Shock

  • Intimidate

These effects all stack together, turning Spider into part of a global damage amplification package.

This is why almost every high-end build guide recommends Spider by default.

A-Tier: Aspect of the Cat (High Synergy, High Ceiling)

Best for: Crit and speed-based builds

Aspect of the Cat has excellent synergy — but only with the right types of builds.

It provides:

  • Crit chance

  • Accuracy

  • Attack speed

  • Cast speed

Perfect Fits for Cat

Aspect of the Cat synergizes best with:

  • Flicker Strike

  • Cast on Crit

  • Tornado Shot

  • Blade Vortex

  • Ice Shot

  • Kinetic Blast

These builds already scale:

  • Speed

  • Crit

  • Hit frequency

Cat amplifies what they already do best.

Skill Expression and Optimization

Cat has a high skill ceiling. Advanced players can:

  • Sync cooldowns with Cat phases

  • Use Farrul’s Fur to control uptime

  • Abuse power/frenzy charge interactions

This makes Cat extremely powerful in optimized setups.

Why Cat Isn’t S-Tier Synergy

Cat fails to synergize with:

  • DOT builds

  • Minions

  • Totems

  • Low-crit builds

If your build doesn’t care about speed or crit, Cat is mostly wasted.

That’s why Cat is A-Tier instead of S-Tier.

B-Tier: Aspect of the Avian (Minion and Party Synergy)

Best for: Summoners and group play

Aspect of the Avian is unique because it:

  • Buffs allies

  • Buffs minions

  • Provides movement speed

Where Avian Fits Perfectly

Avian synergizes well with:

  • Necromancer

  • Guardian

  • Aura stackers

  • Party MF characters

In these setups, Avian increases total party DPS, not just your own.

Movement speed is also valuable for:

  • Minion positioning

  • Dodging mechanics

  • Faster map traversal

Why Avian Is Not Higher

Avian is limited because:

  • It only provides self-buffs

  • No enemy debuffs

  • Lower damage scaling than Spider

It also feels weak for:

  • Solo play

  • Non-minion builds

  • Boss-focused characters

Avian has good synergy in niche roles, but not universally.

C-Tier: Aspect of the Crab (Tank-Only Synergy)

Best for: Pure defensive builds

Aspect of the Crab is the most restrictive Aspect in terms of synergy.

It provides:

  • Physical damage reduction

  • Only while stationary

  • No offensive stats

Where Crab Actually Works

Crab synergizes with:

  • Juggernaut

  • Champion

  • Armour stackers

  • Hardcore characters

These builds already focus on:

  • Physical mitigation

  • Facetanking

  • Standing ground

Why Crab Has Poor Synergy

Crab actively conflicts with:

  • Dodge-based builds

  • Evasion

  • Spell suppression

  • Fast movement playstyles

Most modern builds rely on:

  • Movement

  • Recovery

  • Avoidance

Crab encourages the opposite.

This makes Crab the lowest synergy Aspect in the game.

Build Synergy Tier List

Tier Aspect
S-Tier Aspect of the Spider
A-Tier Aspect of the Cat
B-Tier Aspect of the Avian
C-Tier Aspect of the Crab

Why Spider Is the Ultimate Synergy Aspect

Aspect of the Spider is S-Tier synergy because:

  • It never conflicts with builds

  • It scales all damage types

  • It fits all archetypes

  • It stacks with everything

There is no situation where Spider feels wrong.

In a game as complex as Path of Exile, that level of universality is incredibly rare.

That’s why, from a pure synergy perspective, Aspect of the Spider is the most perfectly designed and most universally useful Aspect Skill in Path of Exile.
