Acquisition[edit]

Swords with a Vampiric mod, Hundred Blades, Order of the Vampire, Conjure Flame/Frost/Lightning, etc. synergize well with Sun and Moon Slash because the effect triggers twice.
Unlike Dual attacks, both attacks from this skill hit simultaneously, meaning both hits will connect even through skills such as Shield Bash or Shield of Judgment.
