The Magic Circle is much bigger and based on the runes and symbols on the Magic Circle, I am perfectly sure it is a 7th tier magic. It's a pretty common magic circle among magicians who already got their class upgrade.
But, the only creatures capable of unleashing a magic circle of this caliber are boss monsters and some Elite Tier enemies that have the job or affiliation to magic knowledge. I have never seen a boss that is just a goop use magic of this scale.
The magic immediately fired off, and from the looks of it, it looks like the modified version of [Dark Ray], a 7th tier magic that only the Magician class up, Black Magician can use. However, this one is much more powerful since this version [Dark Ray] is more focused and only appears as one beam compared to the [Dark Ray] that Black Magician's form which is scattered and smaller beams to deal with multiple enemies. This one is specialized to deal with AOE damage while maintaining itself as one single beam.
