Path of Exile 2 Gemcutter's Prism FAQs
What types of skill gems benefit most from Gemcutter's Prism?
Damage gems with high base output, support gems with strong multipliers, utility gems with uptime effects, and Spirit gems with reservation costs gain the most from quality upgrades. Always check the specific quality bonus of the gem.
Should I use Gemcutter's Prism early or save it for the endgame?
Use it strategically. Early-game use is fine for minor damage spikes, but Prisms are most effective on high-base-value endgame gems that are central to your final build. Prioritize gems you know you will keep.

How do I know if a gem's quality effect is worth investing in?
Check the in-game skill panel (often by holding Alt on PC) to view the specific quality effects for your gem. Prioritize gems with impactful bonuses like increased damage, longer duration, or reduced Spirit/Mana reservation cost.
Can I use Gemcutter's Prism on Spirit Gems?
