Boss mechanics

Disobedient

This was a tv show but it was so cool. Deep, deep down on a dungeon’s bottom floor was a giant skeleton grim reaper, with flaming blue eyes, torn robe and a scythe bigger than his massive body was waiting. The candelabras around the cavern lit with blue flames, giving an eerie ambiance. One of his attacks were the blue flaming candelabras went out, causing pitch black darkness, then blue flames starting from where the was boss was last see were sent out in waves, lines and balls all of which had to be dodged or blocked with a elemental water shield. I thought this was an incredible scene, would be cool if a game boss did something like that lol

Would be great to hear what show it was from so that we might be able to see it ourselves
