Sonic/Sonic

I've got him to 50, but unsure as to how to build him outany advice?

After the rework Sonic Blast really only needs a few Single Target powers alternating each other in order to cap out the -res debuffs.
Realistically you can get by with just Scream and Shriek and Dreadful Wail; plus Siren's Song and/or Aim. (And perhaps a procbombed Weaken Resolve...)

 

Shockwave and Siren's Song and Aim don't inflict any -res; but the rest all inflict Sonic Vibrations #1 (-12% res for 12s; doesn't stack) plus one other type:

Scream and Shriek and Shout and Screech all  inflict Sonic Vibrations #2 (-8% res for 12s; stacks up to 4 times)
Howl inflicts Sonic Vibrations Wide (-8% res for 12s; doesn't stack)
Dreadful Wail inflicts Sonic Vibrations Extensive (-8% res for 20s; doesn't stack)

Siren's Song also deals decent damage now, on top of inflicting a Mag3 sleep.

As for Sonic Resonance?

Skip Sonic Cage and Sonic Repulsion and maybe Clarity (personally I take it, as IMO being able to preemptively stack enough mez protection on your allies to let them ignore the likes of Ghost Widow's Mag100 hold is worth the power pick). Slot the rest. Even Liquefy is worth taking now ever since its recharge time was drastically reduced - it wants ED-capped recharge and -ToHit.

My closest relevant toon is a Sonic/Elec/Mu: Defender - Sonic_Elec (Energize+TCage).mbd zDefender - Sonic_Elec (AidOther+NoSJ).mbd
(I flick between ArcaneWard+Energize and AidOther+AidSelf; but the former is probably a smidge better performing)

Also, don't be surprised if sometimes whenever you throw out a Siren's Song; it seems like the sleep doesn't work. Whilst the damage built into Siren's Song doesn't override its own sleep effect... unfortunately additional damage from other sources such as your Interface Incarnate slot will still wake 'em up. So if you ever find yourself soloing on higher difficulty levels it can make sense to slot a NON DAMAGING interface slot like Diamagnetic instead of Degenerative/Reactive.

Personally I'd still lean towards a different secondary; but sometimes thematics trump performance 🙂
