Eclipse adds damage and survival to short trades that land a shadow and shuriken together, while Serpent's Fang pressures shield-heavy targets. Serylda's Grudge penetrates Armor, Spear of Shojin accelerates ability rotations after Death Mark, and Guardian Angel provides a safety net after a backline assassination. In the combo simulation, Electrocute triggers on the third hit and most reliably reinforces the short burst window.
