TACTICS
Before Combat A PRANKSTER Operative uses Silent Spell and Still Spell with her enchantments, attempting to keep any disruption of her cover to a minimum.
During Combat A PRANKSTER Operative casts improved invisibility and then uses bestow curse, dominate person, and blindness/deafness to incapacitate foes before she dispatches them with her elven curve blade.
Morale PRANKSTER Operatives are highly valued by the cabal but avoid capture at all costs, fighting to the death if they cannot flee when reduced to 12 hit points or less.
