Paw sweep: A paw appears at the top-left corner of the Bullet Board and sweeps in an arc to the top-right corner, leaving a trail of fireballs. When the paw reaches the other, the fireballs will launch towards the SOUL and bounce off the walls. In later rounds, the attack contains a second paw that starts at the bottom-right corner and mirrors the first. This attack ends immediately if the SOUL touches either paw.
Fire waves: Streams of fireballs fall from the top of the Bullet Board in a crisscrossing double-helix pattern and accumulate at the bottom. The streams have holes in them to dodge through, and this attack also has a safe spot in both top corners.
Fire waves 2: The Bullet Board is shorter, and fireballs are hovering at the sides. The safe corner spots still exist despite this but are smaller and harder to reach.
Fire helix: Thicker streams of fireballs, too thick to dodge through, but they do not sweep back and forth, allowing a careful SOUL to remain safe between the streams.
Faltering: Fireballs fall haphazardly from the top of the Bullet Board, but deliberately move away from the SOUL if they come close, making it impossible to take damage from this attack. If the protagonist's HP is 2 or less, Toriel will use this attack exclusively, and she will end her other attacks immediately if they reduce the protagonist's HP to 2. She will also use this attack after the 11th Spare, regardless of health. After the 12th, she stops attacking entirely.
It is still possible to die in this fight by taking a high damage attack before entering critical health. If the protagonist does die during her battle, Toriel gasps in horror for one frame before the "GAME OVER" screen appears.
