The Explorers expansion is intended for use with Dark Souls: The Board Game. 

New Dark Souls: The Board Game adventurers await in the Explorers expansion, with new enemies, new encounter cards utilising those enemies, and new treasure cards for characters to discover along their adventures. Componenets for one new mini boss encounter and one new main boss encounter further enhance players' options and provide fresh challenges. 

The Explorers expansion also includes 18 terrain miniatures to replace all of the gravestones, barrle, bonfire, and treasure chest tokens from Dark Souls: The Board Game, while the new Mimic ambush rules mean each chest could turn into a dangerous (but rewarding) foe!
