Flint is a Harvest Sprite in Harvest Moon: Skytree Village.
Flint is the Harvest Sprite of rocks and ore. He lives at the Harvest Goddess Spring. Talk to him to spawn additional ore to mine.
There is no gift-giving in Skytree Village. The only way to build chemistry is to talk to the villagers every day. Unlike previous games, chemistry will not decrease if you do not talk to someone for awhile.
Flint can be found at the Harvest Goddess spring from 8am-8pm.
