Scythe Summons LS Tie Fighters

If the ally Capital Ship is Executrix, at the start of battle summon two crewless Imperial TIE fighters, and while an ally Imperial TIE fighter has Foresight, they are also Marked. The first time an allied Imperial TIE fighter defeats a ship, all allies gain 100% Turn Meter.

Inflict Speed Down, which can't be evaded or resisted, on Jedi enemies for 2 turns. If the allied Capital Ship is Executrix, inflict Fear on all enemies for 1 turn, which can't be copied, dispelled, or evaded, and summon two crewless Imperial TIE fighters.

Either with the unique or reinforcement Scythe summons maximum of 2 Tie Fighters and they seem to be having LS tags rather than DS. 

There are some ships that do more vs DS and/or Empire ships.

An Example 2nd Special of Han Falcon :

Deal Physical damage to all enemies and grant all allies Defense Penetration Up for 2 turns. This attack deals 25% more damage for each Dark Side and each Empire enemy.
