Wait for all the spells and abilities to appear. Hover your mouse over each spell/ability and see what happens. Every 10 seconds, they blink as well. If they turn into a shade, click him to revive them. Circle all around the knight, touching every spell and charm, will give you a glitch. Every sound effect at once. It broke my PC after a while, so don't do it too much.
This little guy can do BIG things and have BIG dreams. Credit to Team Cherry for the amazing Metroidvania game Hollow Knight. I do not own any of these sprites you see before you. Team Cherry owns everything except the slight redesign of Ghost and its Shade.
