Be aware that any attack action can only target one square : if you have a quickened Thug or SC with a frost brand, a horned helm, and a kick attack, if your frost brand kill all units in the target square with its area frost effect, the gore and kick attack will be wasted.

However, quickness add another attack action, meaning you can then target another square, and such secondary attacks are useful to make sure that you kill any unit that survive the area attack, and do not waste your second action by targeting the same square where there were just one injured target remaining.
