Keystones are passive skills in Path of Exile 2 that provide unique effects that could alter a build in more ways than one. With each new league in PoE 2, a lot of balancing changes will be implemented that may change how powerful certain keystones perform, especially when taking gear and other passive skills into account.

So, in this article, I will talk about only the best keystone passives in Path of Exile 2: The Last of the Druids. The ones that are going to be mentioned here are based on user data from the forums and PoE Ninja.

Now, keystones are one part of the equation; your choice of gear could influence how powerful your build is going to be. That said, if you need currency to buy pieces of gear for your build, visit our PoE 2 Store to get your much-needed supply!

What Are Keystone Passives in Path of Exile 2?

An article about the best keystone passives in PoE 2 will not be complete without first explaining what they are. Keystones are passive skills, which grant bonuses that you cannot find anywhere else.

For instance, Primal Hunger is a new keystone introduced in Patch 0.4.0 that greatly increases your maximum Rage. It also allows you to regenerate Rage passively without doing anything. The catch? Rage has no inherent effect, which means that you don’t get any bonus attack damage per point of the said resource.

Primal Hunger’s combination of effects can be found on the passive tree, albeit you have to spend multiple points to achieve an almost similar result. That is pretty much what keystone passives have to offer in Path of Exile 2, and that is why most builds take at least one of them to thrive.

Keystone Passive Changes in the Last of the Druids

GGG has added three new keystones in Patch 0.4.0 that have something to do with the new class in PoE 2, the Druid. These are:

• Lord of the Wilds: Lets you equip a sceptre in the offhand (with a Talisman on the main hand) at the cost of 50% less reservation efficiency.
• Primal Hunger: Grants a huge boost in Rage and provides passive Rage generation. However, Rage does not increase attack damage anymore.
• Wildsurge Incantation: Significantly increases the damage of Storm and Plant spells. Wildsurge Incantation makes these spells cost 50% less resources to cast as well. Despite that, however, they have considerably less duration, prompting you to cast them more often.

It is also worth noting that some keystone passive skills only appear to be useful. Oftentimes, in The Last Druids expansion, they’re taken only to get notable passive skills on the tree without being connected to them. This is possible by playing the Oracle ascendancy class for the Druid, since it’s the only one capable of doing so when “Entwined Realities” is allocated.

Best Keystone Passives in PoE 2: The Last of the Druids

Here we are in the section you’ve all been waiting for! Keep in mind that the keystones that will be highlighted here are presented in no particular order. This is due to the fact that all of them are great in their own way, and it’s up to you if they are worth allocating for your specific build or not.

Blood Magic

Blood Magic is quite a popular keystone passive in Path of Exile 2: The Last of the Druids. This is primarily allocated by Spark Blood Mage builds, especially those that wear Atziri’s Splendour. That’s because the said armor already converts half of the mana costs of corrupted skills into life anyway, so why not head in that direction, no?

Pathfinders also find value from the Blood Magic keystone passive. This ascendancy class is quite popular for those who want to utilize a Cast on Critical setup to automatically cast Comet. The reason for this is that such Pathfinder Builds would go all the way to the left side of the passive tree, making Blood Magic an easy choice. Path of the Sorceress must be allocated to achieve this.

Chaos Inoculation

Chaos Inoculation remains a popular choice among many Path of Exile 2 players, particularly because it makes you immune to all forms of chaos damage, as well as bleeding effects. Sure, it reduces your life to just 1 HP, but that can easily be rectified by wearing only the best PoE 2 items.

The new ascendancy class, Disciple of Varashta, can allocate CI without any downsides. If anything, the Disciple of Varashta calls for it because of her “Sacred Rituals” ascendancy node, which grants physical damage reduction based on 60% of her current energy shield value.

Other spellcasting ascendancies, such as the Stormweaver, Ritualist, and Oracle, can benefit from Chaos Inoculation pretty well. Do you like melee builds in PoE 2? The Invoker ascendancy class can take Chaos Inoculation and survive in Tier 15+ maps with ease!

Eldritch Battery

Eldritch Battery is famous among Blood Mage and Oracle players. The Blood Mage utilizes this keystone as a way to greatly improve survivability by also allocating Mind Over Matter. To maximize its effect, you must wear pieces of gear that have energy shield as their main defensive layer.

While some Oracle Builds do benefit from the main effects of Eldritch Battery, this keystone is often used as a means of allocating notable passive skills in its radius, namely Raw Mana, Arcane Intensity, Ether Flow, and Controlling Magic.

Elemental Equilibrium

Stormweavers always find the Elemental Equilibrium keystone quite useful, mostly because it allows them to create elemental infusions that are different from the natural element of their chosen spells.

For instance, casting Spark will create cold infusions instead of lightning infusions. This interaction is quite welcome since Spark interacts with cold infusion to make it fire projectiles in a circle (instead of in random directions).

Elemental Equilibrium is popular among Stormweavers because this ascendancy class has certain nodes that can influence elemental infusions (aka remnants) in one way or another.

Refracted Infusion, for example, is an ascendancy node that enables the Stormweaver to gain another elemental infusion that is different from the one that was just picked up.

Other spellcasting ascendancy classes, like the Blood Mage and Disciple of Varashta, can also take advantage of Elemental Equilibrium. That is because most builds that use these ascendancy classes have different elemental spells in their kit, enabling them to get all three infusions.

Iron Reflexes

Warrior and Druid players in PoE 2: The Last of the Druids allocate Iron Reflexes as part of their builds. This keystone passive is simple: it converts all evasion rating on gear to armor for a massive increase in physical damage reduction.

Iron Reflexes is a keystone that is good for armor-based classes in Path of Exile 2 because it lets them wear gear with more than one defensive layer, such as The Vertex and Morior Invictus, and still get tons of benefits from them, defensively.

If you are planning to create a Rampage Bear Druid soon, then consider saving a passive skill point for Iron Reflexes.

Lord of the Wilds

Werewolf Shamans almost always take this next keystone passive, which is the Lord of the Wilds. This keystone is awesome because it lets you equip a sceptre while also wielding a two-handed talisman in the main hand, provided that the sceptre is not a unique one (like the Palm of the Dreamer).

Sure, Lord of the Wilds does come with downsides, but Werewolf Shamans do not care about the penalty to Spirit at all. This is due to the fact that most minions come from the “Pounce” skill, which does not require Spirit to summon.

Now, the 50% less reservation efficiency is significant in certain scenarios, particularly if you want to use more than two auras at the same time. If that is the case, get a Sceptre that has a couple of “% Increased Spirit” modifiers to circumvent that.

Mind Over Matter

Mind Over Matter (sometimes referred to as “MoM”) is a keystone passive skill in Path of Exile 2 that is primarily allocated to improve your survivability. It makes all damage you take reduce your mana first before your life. Sometimes it is paired with Eldritch Battery, though most players in The Last of the Druids expansion use Mind Over Matter in conjunction with Chaos Inoculation instead.

To get the most out of MoM, wear items that have “+ to Maximum Mana” on them to significantly increase your mana pool. If you have Eldritch Battery allocated, equip pieces of gear that have a few energy shield modifiers.

Whispers of Doom

In case you were not aware, you can only apply one curse to a target at any time in Path of Exile 2: The Last of the Druids. That is a hard limit that can only be bypassed if you have the Whispers of Doom allocated. Whispers of Doom allows you to apply two different curse skills at the same time.

Now, because this keystone doubles the activation delay of curses (which is already quite long by ARPG standards), curse skills are frequently activated using the Blasphemy meta skill. Blasphemy effectively turns curses into vile auras, alleviating the need for manual casting since their effects are applied in a radius.

That said, Whispers of Doom is utilized by many Ritualist and Lich builds in PoE 2 that want to inflict Enfeeble and Temporal Chains upon their foes.

Wildsurge Incantation

When Path of Exile 2: The Last of the Druids was showcased by GGG, I expected plant skills like Entangle and Thrashing Vines to be underutilized, compared to other devastating spells like Thunderstorm, Icestorm, and Tornado. Fast forward to now, and boy, was I wrong!

Part of the reason why those new plant skills are viable is because of the keystone passive called Wildsurge Incantation. This keystone provides a huge damage boost to all storm and plant spells, which includes the ones that I’ve already mentioned.

While it does make these spells last a noticeably shorter duration, that is actually fine because you will be casting them regularly anyway. The Disciple of Varashta, Stormweaver, Blood Mage, and the Shaman are ascendancy classes that can find good value out of the Wildsurge Incantation keystone passive.

Oracles, on the other hand, mostly use the said keystone to gain access to Sacrificial Blood, Illuminated Crown, and Intense Flames without spending too many passive skill points.

Zealot’s Oath

Energy shield is still the strongest defensive layer in Path of Exile 2. That is why you will see many players favoring ES over evasion and armor because it’s quite reliable in helping you survive in the endgame. Plus, when you have tons of energy shield, you can allocate Chaos Inoculation for even more survivability!

Having said that, Zealot’s Oath is a keystone that recovers your energy shield based on the excess life recovery provided by your passive life regeneration. To put it simply, the higher your life regenerated per second is, the more consistent your ES recovery becomes.

Keep in mind that allocating Zealot’s Oath essentially prevents your energy shield from recharging on its own. Therefore, you must improve your life regeneration through gear and passive skills if you want to get the most out of it.

I also recommend that the majority of your items have “+ to Maximum Life” as one of their modifiers. Putting a bunch of Soul Core of Jiquani also helps in this regard.

Overview of the Best Keystone Passives in PoE 2: The Last of the Druids

FAQ

What is the Strongest Keystone Passive in PoE 2 Right Now?

Based on usage rate, Chaos Inoculation remains a top choice among many players in Path of Exile 2: The Last of the Druids. The fact that you can heavily invest in energy shield-based gear and be immune to chaos damage and bleeding is enough to warrant an allocation of this keystone.

Are All Keystone Passives Viable in Endgame Content?

If we’re talking only about the keystones mentioned in this article, then yes. However, not all keystones are viable for tackling endgame content. The “Oasis” keystone, for example, might be useful for leveling, but it’s definitely not good for fighting against pinnacle bosses, since charms provide tons of value in the late game.

Which Keystones Work Best for Druid Builds?

These are the ones that I find to be great on Druid Builds in The Last of the Druids expansion:

• Wildsurge Incantation: Especially for Druid Builds that use any of the plant skills mentioned earlier.
• Iron Reflexes: Shapeshifting Shamans can surely benefit from the additional armor from evasion-based gear.
• Lord of the Wilds: Having the ability to equip a sceptre without any offensive downsides is amazing. Just be sure to get the right sceptre to address the issue with less reservation efficiency.
• Primal Hunger: If you want to spam your Druid Skills, you can consider taking Primal Hunger. Do take note that the power loss from allocating it should be addressed by equipping the right weapons and gear.

Can Beginners Safely Use Keystone Passives?

Absolutely! Before allocating any keystone passive, though, it’s best that you read its effect first and discern whether it benefits your current build or not.

How Hard is it to Respec a Keystone Passive in PoE 2?

Not that hard, actually. All you need to have is gold, and you can freely remove the keystone passive from your build very quickly. Talk to Doryani in your hideout to respec your passive skills (including your keystones).

Do Keystone Passives Change Between Leagues?

Not necessarily. In most cases, all keystones have the same effects as they did the day they were introduced. There are some exceptions, of course, such as Eternal Youth, which used to let you recover energy shield by using a Life Flask.
