"A secret art unleashes a gush of souls.
The homing soul mass pierces its target, then hits repeatedly for additional damage.
This blasphemous spell is a family heirloom of Lord Aldia's. It was designed to pummel foes until its power is entirely exhausted."
- Aldia's Keep: In the acid pit with the mutant rat monsters.
- Shoots four Soul Spears each dealing magic damage. Can pierce through multiple enemies. Each Soul Spear deals around same damage as a Great Heavy Soul Arrow. If all four spears connect, it is the highest damage dealing sorcery in game.
This spell is also used by Leydia Pyromancer, they cast this spell with Blue Flame straight sword catalyst.
- Not useful on small targets, but very useful against big, slow enemies such as bosses. Casting speed is roughly same as Soul Vortex. Length of staff affects its starting cast point, making it miss at short range with a Staff of Wisdom.
Prior to calibration 10. it was considered to be the only useful spell against Old Iron King, it deals approx 800 damage to him at NG+4 onward, higher than Great Resonant Soul due to the boss' dark resistance.
As of calibration 10. this spell suffered major poise damage downgrade.
