Longdead Archery vs SC's/High Quality Summons

[Saber Cherry]

Ethereal and Astral Shield cannot block magical arrows. Luck and Twist Fate can.

SCs are usually regenerating (if alive) or immune to Bane venom (if dead). Live SCs are also often poison-resistant to some extent. Bane venom is not automatic death; with high HP, poison-resistance, regeneration, and reinvigoration, an SC will normally survive Bane venom unharmed. But it will certainly make it easier for other units to take out, as the reinvigoration and regeneration will have to deal with Bane effects in addition to normal damage and fatigue.

Staff of Storms is also a pretty effective counter, if the SC is not solo.
