Soul Crusher
Defeat the betrayers within three and a half minutes.

This battle occurs shortly after escaping from Goose. As usual, skip all cutscenes. You will only be fighting against one this time, while the other will summon magic to protect the main attacker.

Use your favourite weapon or Dark Hand to inflict damage. Just like your previous battle with them, after being hit they will teleport away. Swing your sword and attempt to get an extra 1-2 hits beforehand. Repeat this strategy until she is defeated and a cutscene will play. After the cutscene, you will be fighting the other. She will have minimal health, but will unleash a continual barrage of magic. A couple of hits with your magic or sword will end the battle and unlock the trophy.
