Alter Center Mass

Up to three creatures of your choice that you can see within range must make Constitution saving throws as you generate minor mass effect fields that alter their center mass. Whenever a target that fails this saving throw makes an attack roll or a saving throw before the power ends, the target must roll a d4 and subtract the number rolled from the attack roll or saving throw.

At Higher Levels: When you cast this power using a power slot of 2nd level or higher, you can target two additional creatures for each slot level above 1st.
