The Arcanist's Etcher plays a pivotal role in enhancing magical weapons—specifically wands, staves, and sceptres—in Path of Exile 2 by increasing their quality up to a maximum of 20%. Unlike martial weapons, which use Blacksmith's Whetstones to boost quality, caster weapons rely exclusively on Arcanist's Etchers for this purpose. This quality boost is crucial because it directly improves the skill granted by the weapon, effectively acting like a gemcutter prism but for the weapon’s inherent spell skill.

Quality on caster weapons does not increase physical damage as it does on martial weapons. Instead, it enhances the base properties of the skill granted by the weapon. For example, increasing quality on a wand or staff amplifies the damage, mana efficiency, or other unique effects of the spell it provides. This means that even though caster weapons lack traditional weapon damage stats, their quality upgrades translate into tangible improvements in spellcasting performance.

Applying Arcanist's Etcher is simple: players right-click the Etcher and then left-click the target caster weapon to incrementally raise its quality. Each application adds roughly 2% to 4% quality, and multiple applications are needed to reach the 20% cap. Because these Etchers drop relatively rarely—primarily from monster kills, chests, and salvaging caster weapons—players are advised to conserve them until reaching mid to late game stages, where the difficulty spikes and quality upgrades become more impactful. Many players seeking efficiency at that stage opt to buy poe 2 currency to fast-track their crafting process.

The impact of quality on caster weapons can be observed by holding the Alt key while hovering over the skill granted by the weapon, which reveals additional effects gained from quality. Although some tooltips may currently display incorrect values due to bugs, the quality bonuses are still applied in gameplay, enhancing damage and other skill attributes.

Strategically, investing in quality through Arcanist's Etcher is essential for spellcaster builds aiming to maximize damage output and efficiency. Since caster weapons do not scale with physical damage, quality upgrades become one of the few reliable ways to significantly boost their effectiveness. This makes the Etcher a highly sought-after currency for players focusing on wands, staves, or sceptres, especially in endgame content where every percentage increase in damage or mana efficiency can be decisive.
