Heart crystal (activated)

The Heart crystal (activated) is a quest item used in the Legends Quest. It is created by killing the three knights Ranalph Devere, Irvig Senay and San Tojalon in the dungeon under Kharazi Jungle to obtain a lump of crystal, a chunk of crystal and a hunk of crystal, which can then be combined to form the uncharged heart crystal. Once these items are combined, the crystal must be activated by using it in a special location in the dungeon. It can then be used to open a door that accesses deeper parts of the dungeon.
