The Battlefields series has been made to give unlimited options to the wargamer, when he/she decides on what type of bases the miniatures should have.
All the materials are the best quality the market can offer and all Battlefields are packed in Army Sized tubs with enough basing material for many armies.

180ml of Mountain rocks, Basing in a resealable tub. Very realistic rocks on all bases, either to position a hero on or as an addition to a Monster base to create depth.
Most commonly used Rocks for all terrain types, especially Ruins.
