@ariarhythmic @davidrevoy It casts a ring of fire, rather than the fireball you'd get by casting "PyroBolus". (I should know, since I was the one that came up with that spell.) You could also try casting "PyroTriangulus Aequilaterus" to draw a flaming pointer into the air.

Just don't confuse any of them with "Ignisme", or your eyebrows will not be the only part of your body that's on fire.
