I was thinking about the old joke of "where are those onion cutting ninja!" when something makes you cry.

Shinobi technique : Cuts the Onions

Using a variety of scents and sounds, the Shinobi brings forth memories of pain and grief in the victim. While wafting a variety of smells from bottles of oils, and making soft, unheard whispering sounds, make a Skulduggery (air) check with a TN of the target's vigilance. Effect lasts 3 rounds, plus rounds equal to bonus success. Every round, target gains one cumulative strife (one strife round one, two strife round two, so on) as the smells and sounds bring memories of loss. If the target becomes compromised, they must immediately unmask by weeping in grief. Knowledge of a particular loss the target has suffered, such as sound of the person's voice, or a smell associated with them that can be copied with the oils used, reduces the TN of the check by 2 (minimum one).
Opp

1: learn something about the person the target is thinking of. Their name, family/clan, something personal about them, as the target mutters to themselves while lost in memory

2+ add one strife per round per 2 opps spent
