How do you get the Harrowing 2012 - Death Mask?
It was sold in the League of Legends store. Riot's description in the client reads: “Acquired by purchasing at least 500 RP during the 2012 Harrowing event.”
Is the Harrowing 2012 - Death Mask still available?
Probably not. Riot tied the Harrowing 2012 - Death Mask to 2012 (store purchase), and it does not normally bring back past event rewards or bundles.
