Casket of Souls is a Tomb Kings artillery unit introduced in Total War: Warhammer II with the Rise of the Tomb Kings DLC. When the souls are released, they endeavour not to return without new victims to torment for eternity.
At the heart of each tomb of the mightiest king there lies a casket, inscribed with hieroglyphs of malediction. Within this sarcophagus resides the tormented souls of those who have incited a Tomb King's wrath. Powerful binding inscriptions ensure that these souls cannot leave their prison until the moment when the casket is opened. When a Casket of Souls is opened, blinding light spills across the battlefield as countless souls scream into the air seeking freedom from the suffering of their confinement. These spirits plunge through the bodies of the Tomb Kings' enemies, and the hapless victims suffer unbearable agony as their life essence is utterly drained. To die thus is far worse than a physical death, for the very souls of those who perish in this manner become ensnared by the power of the casket. A Casket of Souls is a devastating weapon, for all who look upon it risk eternal damnation and imprisonment.
- ▲ Armour-Piercing Missiles: The damage of armour-piercing weapons mostly ignores the armour of the target, making them the ideal choice against heavily-armoured enemies. They are often heavier and attack at a slower rate though, making them less efficient against poorly-armoured targets.
- ▲ Armoured: Armoured: Armoured units can block damage from any source apart from Armour-Piercing damage.
- ▲ Light of Death: The Keeper of the Casket may allow some of the tormented spirits trapped inside to escape; not for mercy, but to let the damned souls rain down upon a loosely-specified area..
As the superior artillery option over the Screaming Skull Catapult in terms of damage, range, and accuracy, The Casket of Souls may only be recruited through the Great Incantation of Tahoth rite. It is a devastating artillery unit that fires a barrage of missiles with an extremely long range, so is best used against blobs of enemies. The projectiles' high armor piercing allows it to mitigate most armored enemies. They travel at an extremely high vertical arc, and thus will be less accurate at longer ranges as the enemy has more time to move out of the way. It also increases Winds of magic recharge rate just for being present on the battlefield. It is a delicate unit that needs to be protected so that it can deal maximum damage to enemies; it will not survive in melee combat against anything.
