- Absolute Suggestion: Sigyn's suggestion ability is only ambiguously magic. Thus, it's a mystery whether she really counts as a magician or not, not that Gremlin cares as long as they can use her ability. Her ability is that she is able to give a suggestion 100% accurately, and thus can make anyone succeed. For example, when Marian and her wanted to meet up, Marian suggested that Sygin could just give her the suggestion "find the lost Sygin" to find her. Similarly, the narration stated she could use her suggestion ability to make up for Marian's lack of skill in direct combat. However, Sigyn cannot use her ability on herself. Her nature is to give what she has to others to make up for what they lack, so if she tried to be perfect she wouldn't be able to make up for what she lacks. It was hinted that if she did, she could even reach the realm of being a Magic God. She is referenced as being originally able to not only give suggestion to her allies, but also give wrong suggestions to the enemy and cause them to self-destruct.
