Starsight Sap

The woods of Elori are home to old and ancient trees, some of which ooze starsight sap. A single drop grants the user night vision to keep working late into the night, and it boosts the potency of spells cast by mages. The elves have amassed large reserves of the sap and use it in many rituals. The Dwarven Holds have found it useful in creating more powerful enchantments for items. However, too much starsight sap can blind a user or overcharge a mage's spell and kill them. While it isn't tightly regulated in most places, the Serpent Theocracy treats starsight sap like a poison and Orsia does not allow it do its magic-boosting properties.
