Misdirect duration upgrade and Illusions question

By Metushelah, in Star Wars: Force and Destiny RPG

Hey guys,

I wanted to ask you about the Misdirect Illusion duration upgrade as it relates to the strain the target suffers when you activate it via 1 DS pip.

According to the rules he would suffer strain on the count of ALL the pips you invested (even though only 1 was dark). So does that mean that when you then commit 2 force dice to extend the duration, he continues suffering that amount of strain each round?

What about the master illusion upgrade? can you invest your pips on the same target and will be "bombarded" with illusions according to your cunning+deception ranks and EACH of them makes him suffer the number of strain invested? or only those strain invested without the 2 you need to use to activate this upgrade?

how does that compare to the Influence force power?

The Duration upgrade only maintains the Illusion, it does not keep inflicting Strain each round.
