FYI - no matter how much suppression you put on the character -they only take 1 immo token. you cannot freeze any saber users except Op Vader (but he can Spur to move speed 1)
if you double check the wording its "each enemy trooper unit that gains at least 1 suppression token in this way also gains 1 immobolize token"
the wording is not 1 immobolise token per suppression
