Question 1

Why Is Kingmaker So Good for Party Play in PoE?

Accepted Answer

Kingmaker is one of the best party-play items because it provides four incredibly powerful buffs to all nearby allies simultaneously:

Culling Strike: Instantly kills any enemy (including map bosses) when they reach 10% health. This saves a huge amount of time on tough encounters.
+50% Crit Multiplier: This is a massive damage increase for any party members who are using critical strike builds.
30% Increased Item Rarity (IIR): This makes your entire party find more rare and unique items, increasing everyone's profit.
+10 Fortification: This is a strong defensive layer that reduces incoming damage for everyone in the aura.

It's an all-in-one damage, defense, and magic-find boost for your whole team.

Question 2

Does The PoE Kingmaker Aura Affect The Player Wielding It?

Accepted Answer

No, this is the most important thing to know about Kingmaker. The "Kingmaker's Presence" aura (all the buffs like Culling Strike, Crit Multi, etc.)  only affects nearby allies. It does not affect the person who has it equipped.
This is why you almost never use it on your main character. The most common strategy is to equip it onto an Animate Guardian minion, as the minion is considered an ally and will share its aura with you.

Question 3

What Is The Vendor Recipe for Kingmaker in PoE?

Soul Taker (a Unique Siegemaker Axe)
