Ruinous Sigil is a Skill in Dragon's Dogma.
"An advanced form of Perilous Sigil that implants a sigil into the ground that hits long ranging foes with a devastating blast of energy and takes longer to dispel."
- A ball of magic is cast on the targeted location, enchanted with whatever Archmagick the weapon of the caster carried.
- This ball detonates when an enemy comes within range, staggering and knocking down those within its range. Some lighter enemies even get cast high up into the air, taking additional fall damage on their way down.
- Up to two may be placed simultaneously on the battle field.
- Planting a sigil near the weak point of a fallen enemy is devastating, especially if the sigil carries an elemental affinity the enemy is weak to.
