No, there is nothing to pay. As I replied in the thread you need to go back and play earlier levels for higher scores translating into more stars per level until your boosters get strengthened (+1 ones become +2 ones). Good luck.Well this one is easy. You need to choose a +2 boosting artifact at the start of the level instead of the default one.
