A good strategy is to activate it right before attacking and deactivate it immediately after, using it in short bursts. If Shanoa's health is low, using Arma Custos would be a better strategy.
Dominus means "Lord/Master" in Latin, and the Glyph's name roughly translates to "Lord's Agony", with "Lord" referring to Dracula in this case. This glyph does less damage to Shanoa than Dominus Hatred or Dominus Anger.
