Whether in team fights or solo fights with this opener you are usually well advised.
Aim at your opponent or your opponent's running route. First Sonya triggers her Ulti "Wrath of the Berserker" (from lvl 10) and then throws her "Ancient Spear" at the target to pull to him only to give him another one with "Seismic Slam". This combo also works before lvl 10 then of course doesn't trigger the Ulti.
Pitch Front: Seimsmic Slam
Pitch Back: Combo (Ulti-Spear-Slam)
Roll left: Attack
