When a full screen spell is performed, an image flashes on-screen for a few frames. In the Japanese and World 900623 revisions, it's a hexagram, which the symbols inside of it being astrological symbols for Saturn, Mercury, Venus, the Sun, Mars, and possibly Jupiter; the symbols on the outer circle are unknown and possibly made up.

The other two revisions (USA and World 900725) feature a lightning bolt instead.
