The riddle is to kill the slavers by boosting their targets. Even if boosted to the value above the slavers strength, nothing happens. they just keep beeing damaged even tho their strength is higher [contrary to the description of the card]
Ohh damn i stuck more than an hour at this puzzle than i gave up. I just do not see any reasonable method to to solve it.
I'm stuck there too. Spent some time on that puzzle last night.
