The Arena of Shades puts the Nighthaunt against the Daughters of Khaine and introduces a new hero model for each side.
It should come as no surprise that Nagash believes that all souls belong to him and after Morathi’s recent ascension to godhood he has a big reason to hate the Daughters of Khaine. The Arena of Shades puts these two forces against each other in the city formerly known of Anvilgard as Nagash looks to settle the score after the events of Broken Realms. Typically with these boxed starters we see only one or two new models, usually one per faction but in this box we see a five model unit of Craventhrone Guard in addition to a hero for each faction.
While this box is no longer available through Games Workshop directly there are still a few third party sellers with it available. At release the box was $195 USD and considering the fact that you get over forty models, seven of them previously unreleased, this box is a steal. If you price out the individual components these items would easily cost $250 or more. Additionally White Dwarf subscribers will have already received cards to use the new units in Warcry, add these to the already huge lists for both groups in Warcry and you have even more options to help you dominate the field of battle.
