[@Cu Chulainn] No. Mostly on the basis of armor of fafnir. It nulls anything below B-Rank. I'm putting in enemy heroes like Spring Heeled Jack, and Mori Nagayoshi (who on the topic doesn't have a phantasm strong enough to apparently pierce it despite being defense nulling since its C). Once again i'd be in a situation where i'd have to throw in a top tier servant like say Lancelot in these distortions just to give Siegfried a fair challenge outside the boss enemies.
