Honkai Impact 3rd recently released the newest S-Rank battlesuit, Lunar Vow: Crimson Love. For the sake of this guide, the battlesuit's name will be shortened to just Lunar Vow. Lunar Vow is the first battlesuit for fan-favorite character Theresa Apocalypse since Starlit Astrologos in 2020. As is the case with every Theresa battlesuit, Lunar Vow's weapon type is a cross. This Theresa, however, also happens to be a vampire, and her actual attack animations use a large chainsaw.
