Zorutoraku is an offensive magic that shoots either a large blast or multiple smaller blasts of concentrated mana, it is especially effective against both humanoid targets and demons. The caster need only to say the name of the spell while aiming for a target that they can see within the range of 150 feet to unleash it's destructive power instantaneously. Although the spell is simple to use, it however requires greater discipline from the caster to fully use it efficiently.

Focused Mode, you create one big focused mana blast with 2 of the same level spell slots to give you an advantage against the target, it also impose disadvantage on the target's saving throw this time against this attack. This mode of mana blast deals 10d4 piercing damage (Ignore Resistances).

If the Target is a Humanoid or Demon then it must success a DEX saving throw against your spell save DC, or it dies instantly with it's body disintegrated. On a successful save the target still takes damage from the spell.

At caster level 12, you can use the Focused Mode by spending only one spell slot.

At caster level 20, this spell becomes a cantrip and you can still up-cast it using higher level spell slots.
