Wyrm heart

The wyrm heart is a unique drop obtained by killing Lava strykewyrms and its boss variant, the WildyWyrm, in the Wilderness. When attached to a staff of light, it creates the staff of darkness. This process can be undone, but only the heart will be salvaged in doing so. Creating the staff leaves it with 50% charges remaining.

The staff of darkness degrades as it is used. Players can use additional staves of light to recharge it by 50%, however. After 10 hours of combat, it will degrade and consume the staff of light, leaving the player with the wyrm heart.
