In many force powers it does say - You can activate this power multiple times. The Enhance power lacks that. Does this mean that you can only add one Success or Advantage to the enhanced check or you can add one for each "success" you roll on the force dices?

With Enhance they kinda did it backwards. They put in the assumption that you could use effects multiple times unless it says you can't.

So for instance, the Range upgrade days you can't activate it multiple times, so you can only add 1 range band to your Force leaps. The other powers it grants you (Enhancing skills, boosting characteristics) it doesn't say, so the assumption is that you can spend multiple Force points or commit multiple dice to those effects.

This assumption didn't last as new powers were created,so it seems a bit backwards looking at it now.

Thank you. That was my interpretation as well but I just wanted to be sure. With high Force ratings those powers become an amazing skill booster for just 5 xp. (Despite the fact I'm still to find a good use for coordination)

Coordination is manual dexterity and agility along with quick reaction timing.

Balancing on a rock, avoiding a dart trap, sliding under a closing door, crossing a bridge that is falling apart as you run across, dancing, balancing on a finger tip etc.

Athletics is raw physical strength and endurance, jumping across a pit, pulling yourself up a ledge, outrunning a boulder, doing one finger push ups etc
