The skill Leo Ray used was exactly [Thunder Light Phantom Body].
This Tier 5 thunder buffing spell that significantly enhances one's own speed was enough to make Leo Ray's speed unrivaled at the Tier 4 level.
With the assistance of the Power of Divine Grace, Leo Ray's speed received a new boost.
Additionally, Leo Ray also used [Thunder Sky Diversion].
This Tier 5 thunder auxiliary spell, learned not long ago, not only creates a thunder domain around Leo Ray that automatically attacks nearby targets but also enhances the effect of thunder magic.
This includes not only attacking techniques like Thunderfall but also buffing techniques like [Thunder Light Phantom Body].
Thus, with the triple buffs of [Thunder Light Phantom Body], [Thunder Sky Diversion], and the Power of Divine Grace, Leo Ray's movement speed reached a terrifying degree, enough to take on ordinary Tie 5 Powerhouses with the strength of a Peak Level of the Tier 4.
