Ilberd's Lionshead attack was definitely named after his sword used to cut off Raubahn's arm, but he's not even using that sword anymore when we fight him. ¯\_(ツ)_/¯

At least that's my assumption since Lionshead, rather aptly, had a Lion's head on the guard and is easily wielded with one hand. Meanwhile, the promotional image of the Griffin wielding his sword has Ilberd using it with 2 hands and it definitely has a Griffin/Eagle's head on the pommel. Also the blade is much wider, lol SO DIFFERENT SWORDS AND IT BOTHERS ME, OKAY?
