Stone Mask

The Stone Mask is a mask of Jade used in ancient rituals where the heart of a victim is offered to a dark god.

It first appeared in Castlevania: Symphony of the Night, where it gives Defense +2 and an Intelligence boost of +4. This is the same amount of defense that the other mask in the game, the Ballroom Mask gives, but that does not give an INT boost.

It is called the Jade Mask in Castlevania: Lament of Innocence, where it can be used to cause candles to be destroyed by simply walking into them, making the collection of hearts much easier.

It also appeared in Castlevania: Curse of Darkness, where it gives +5 Strength and Constitution, +2 Defense, but is cursed and reduces Luck by 5. It can be created by combining Jade with Sun Tears.

Jonathan Morris can equip the Stone Mask in Castlevania: Portrait of Ruin. It gives him +3 Defense and +1 Luck. It can be compared to the Ballroom Masque, which instead of increasing Luck increases INT by 1 (and also gives a DEF +4). In this game, it is the Skull Mask that is cursed, which increases DEF greatly by 13, but at the cost of 3 INT, MND, and LCK.
