A Dramen Branch is obtained by cutting the Dramen Tree on Entrana dungeon. It's used in the Lost City quest to make the Dramen Staff. A knife is needed to craft the staff.
When the player attempts to cut the Dramen tree, a level 95 Tree spirit will spawn and stop the player from progressing until they kill the spirit, which will not engage the player in combat until it is attacked. Once the Tree spirit is dead the tree may be cut with an axe in order to obtain the branch. The player will only need to kill the Tree spirit once; after that it will not spawn again, and an unlimited number of Dramen branch may be obtained.
