Ahh ok, I think I understand now, thank you! Earlier, the beast says your armor is strong enough to walk on spikes. You do not need the beast near the spikes. As the knight, you can walk across them to jump up to the crystal from the platform.
just finished replaying the game :D adjusted my ratings, thanks for that.
or also use that as a reminder, that some player doesn’t really pay attention to the text in the game and just rely on previous gaming experiences.
