But with Crown of Eyes equipped:

Iron Will's Spell Damage scaling directly increases your Attack Damage as well.

This means:

Every point of Strength now double-dips
Projectile builds scale exponentially better
High-Strength Mercenary builds become extremely efficient

This combination creates a unique identity for Path of Exile 2 Currency projectile melee builds, Strength-stacking Bow users, and hybrid ranged bruisers.

3. Accuracy-Based Attack Builds

Because Crown of Eyes gives up to +200 Accuracy, it pairs well with attack builds that already:

Scale crit
Aim for a high hit chance
Rely on fast attack cycles

This makes it a strong option even outside of spell hybridization.

Is Crown of Eyes Worth Using in the Endgame?

Absolutely. While many uniques fall off as players approach red maps and boss-tier content, Crown of Eyes remains relevant because its core mechanic-Spell Damage applying to Attacks-always scales.

If anything, it gets stronger as:

You find more Spell Damage gear
You unlock more passive tree nodes
You gain access to more endgame uniques that synergize with it

As long as you can handle the Fire Resistance penalty, Crown of Eyes is viable well into the highest tiers of content.

Conclusion

Crown of Eyes is one of the best early and midgame uniques in Path of Exile 2, offering exceptional build flexibility and powerful damage scaling. Whether you buy it, chance it, or cheap POE 2 Currency find it naturally, it opens build paths that would normally require far more complex gear setups.
