How to dodge

Asriel's kit is rainbow and star shaped. Fire Magic shows up before the true final battle line and hits softer than the rest. Named attacks players look up include Star Blazing, Shocker Breaker, Chaos Buster and Chaos Blaster, Chaos Saber, and Hyper Goner.

  • Star Blazing: large stars fall and burst into rings. Galacta Blazing is the spinning upgrade.
  • Shocker Breaker: lightning hits the board after [!] warnings. Shocker Breaker II adds targeted strikes and a left-to-right sweep.
  • Chaos Saber: blade swipes across the board, then leftover sparks fly. Chaos Slicer is faster and adds a sixth swipe.
  • Chaos Buster: a blaster fires wave patterns, then a charged beam. Chaos Blaster fires at random and the beam bursts across the board.
  • Hyper Goner: the board fills the screen, a vortex pulls the heart, and a hit drops HP to 1. Later hits during that stretch deal no damage.

In the larger Angel of Death form, the menu locks to Struggle until SAVE appears. Comet waves come in from the sides and can hit you even while you are on the menu. In this project, arrows move, Z selects, X cancels or speeds text, and P toggles shake.

Spoilers

The SAVE stretch

After Hyper Goner, Struggle does nothing for several turns. Then ACT becomes SAVE. You save Undyne, Alphys, Papyrus, Sans, Toriel, and Asgore as Lost Souls. Each save heals you. Fighting them misses. After all six, Someone else opens the slideshow that ends the fight.
