Games Workshop 71-16 Warhammer AoS - Easy to Build : Stormcast Eternals Celestar Ballista;

The Sacristan Engineers of the Sacrosanct Chambers hail from the Ordinatus Conclave - sometimes known as the Conclave of the Thunderbolt for the devastating effect it can have on battle. These warrior-engineers command the chambers' magical field artillery. When a Celestar Ballista is set up to defend a sacred site, approaching too close can mean an explosive death. Their rune-inscribed projectiles are filled with coils of stray lightning coaxed down from the top of a Sigmarabulum, and are launched like streaks of blue-white energy at the foe. Should their strike be true, they will blast right through the target in a chain explosion of arcane force.
