Fires a piercing crystal soul spear that can go through a line of enemies. Once fired, this spell has limited homing abilities and often serves as a superior option to Soul Stream when dealing with mobile enemies.
Crystal Soul Spear is the most powerful spell available but also has the most expensive cost in FP and has a slow casting time. It acts just like Soul Spear but grants the caster more damage output and the possibility to pierce through enemies, damaging others.
On a fully optimized build, a single cast of Crystal Soul Spear is capable of shaving off more than half of the HP bar of another player of equal Soul Level, provided that no defensive buffs like Blue Bug Pellet or (Great) Magic Barrier are active. This means that, under the most optimal circumstances, it is possible to kill an opponent in just two casts, or even one if they have low Vigor. However, the spell's long casting time and comparatively slow travel speed means that it is very difficult to hit a target that can see it coming, and as such it is only recommended to use this spell when targeting a distracted player (such as during invasions) or to combine it with Homing Soulmass as a roll-catching mechanism.
