As the topic says, blasting a combofield only grants its effect in 360 range like retalation. If you blast the combofield with Phase Smash on a range higher than 360 you dont get the buff yourself. So you get handled like you dont teleport (like Drop The Hammer), but you get interrupted by static fields, lines etc. when using Phase Smash.
So either remove that you can get interrupted, or add the selfblast.
