Hey quick question, cuz Im not sure what this is about since Im only lvl 58

About Ricochet, it says its a 100 potency strike on target and 200 split on nearby enemies.
But what happens if there are none? Its a simple 100 potency strike? or it becomes a 300 potency?
Also what happens if there are 2 targets? is it a 100 potency on target and 200 on the one at its side? or is it 200 on target and 100 to the one at its side?
