When an elemental attack build starts feeling flat against tougher rares and bosses, the problem is not always a weak weapon. Sometimes too much of the sheet DPS is being filtered out by enemy resistance. That is where the Soul Core of Topotante deserves a serious look in Path of Exile 2, especially after patch 0.5.5 raised its Martial Weapon effect from 15% to 25% Elemental Resistance Penetration. For players planning their next upgrade with limited Path of Exile 2 Currency, this change can matter more than another small increase to listed weapon damage.

Why 25% Penetration Changes the Feel of a Build

Topotante does not add a flashy burst effect or directly increase the weapon's base hit. Instead, it improves the portion of elemental attack damage that actually reaches the target. That distinction becomes noticeable when fighting enemies with substantial elemental resistance. A weapon may look impressive in the character panel, yet lose much of its impact in a boss arena. Penetration attacks that problem at the point where damage is being reduced, which is why the Soul Core often feels stronger in real encounters than it first appears on paper. The value is also more consistent than a conditional proc because every qualifying attack benefits from it.

The Weapons That Get the Most From Topotante

The clearest candidates are Martial Weapons supporting elemental hit damage. Lightning attack setups can use the penetration to push shock-oriented damage through resistant targets, while fire and cold builds gain the same benefit when their attacks provide reliable elemental output. Physical weapons with strong conversion into one or more elements are also worth testing. Hybrid setups can be particularly comfortable with Topotante because they are not tied to a single damage type. By contrast, a build that remains almost entirely physical will gain little from the modifier. Before socketing it, check the actual damage split of your main skill rather than relying on the skill's visual theme.

When It Beats a Traditional Damage Core

Topotante is not automatically the right choice for every map or progression stage. During the early campaign, enemies often have modest resistance, and a core that supplies raw damage, attack speed, or a useful offensive condition may produce faster clear speed. The calculation changes in endgame content, where high-resistance rares and bosses can expose the limits of a pure damage upgrade. Compare both options on the same weapon, then test them against the targets that normally slow your run. If the penetration core lowers the number of attack cycles needed for a boss phase, its practical value is usually greater than a small tooltip increase.

Boots Give Topotante a Second Job

Socketing the Soul Core into Boots provides 25% reduced effect of Non-Damaging Ailments, giving the item a defensive angle outside the weapon slot. This can soften the impact of Chill and similar effects, which is useful for attack characters that need steady movement and uninterrupted attacking. It will not replace every ailment solution, and the opportunity cost matters if your boots already carry an important core. Still, flexible equipment layouts may let Topotante support both damage planning and comfort without forcing a separate defensive adjustment.

The strongest use case is an endgame PoE 2 attack build whose weapon already delivers dependable elemental hits and whose main obstacle is resistance-heavy content. It is less appealing for early leveling, pure physical setups, or characters that need a different defensive effect more urgently. Test it against your real map bosses rather than judging it from the inventory screen, then compare the result with your available Path of Exile 2 Orbs for sale before committing to a full loadout change.
