Bloodmoon:Heartwood

The UESPWiki – Your source for The Elder Scrolls since 1995

Heartwood is an extremely difficult to find ingredient. It can be harvested from Spriggans or found in chests in some barrows, but is nearly impossible to find for characters of level 3 or higher, after which you will find Belladonna Berries instead. Since most creatures in Bloodmoon are far beyond the ability of such a low-level character to fight, it is highly unlikely that most people will ever see this ingredient.
