Reiger had learned a total of five types of magic from Revelia Leos Alfr, the strongest Magic Guide in the city known as the "Nine Demon Princesses" — three defensive spells and two offensive spells.
The three defensive spells are as follows —
A supplementary defense spell that can enhance both physical and magical resistances, protect the target of the spell, and even slightly heal the target's injuries — "Life-bound Illusion".
A defensive spell that can resist all of an enemy's attacks and protects the target of the spell — "Thin Veil Breath".
And a barrier spell that can completely block the enemy's attacks on both physical and magical levels — "Dimensional Blockade".
From Revelia, Reiger had first learned these three defense spells. It probably was her way of telling him that protecting oneself and one's allies is more important than attacking the enemy.
Then, Reiger had learned the two offensive spells from Revelia.
