Much like Fam Taos, Siegfried is strictly an Anti-Shield card, notably effective against enemies who use Unbreakable Shields. Siegfried by default is just a 2x attack, with the ability to deal even more damage against Dragon enemies (which of course makes him a strong hard counter to Fafnir). But if the enemy has a Shield effect active, Siegfried's attack will bypass it and replace it with a Damage UP effect. As mentioned earlier, Siegfried is notably effective against foes who use Unbreakable Shields, as the only way to remove them is by overwriting it with Damage UP.
Siegfried's Sub isn't anything particularly special; he heals for 8% HP on Skill Activation, and if a target doesn't have a Shield effect active, they have a 20% chance to get a 1-tick Iron Wall. Unfortunately, the chances of getting the Shield is quite low, making it a bonus at best.
Siegfried (also known as Sigurd) is a famous figure in Norse and Germanic Mythology, known for slaying the dragon Fafnir.
