Arrows of Burning Heat
Seek Out Impa Main Quest
Light the four torches surrounding the Goddess Shrine
After completing the Seek Out Impa Main Quest, return to Kakariko Village and speak to Rola, the shopkeeper at the The Curious Quiver, the arrow shop in town. Rola will task Link with lighting the four torches that surround the Goddess Statue in the village, located just in front of Lady Impa's home.
To complete this quest, Link needs to shoot the four torches with Fire Arrows. Link can also use regular arrows, by first dipping the ends of them into the campfire that is nearby. The arrow will stay lit and Link can shoot the torch. Alternatively, Link can use a fire elemental melee weapon and perform a jump strike, lighting the torches that way. Unfortunately, none of these methods will work if it is raining at the current time.
After the four torches are lit, return to Rola for your reward of a Red Rupee.
