Does Ahri's legend give all attacking units -1 Might, or just one? Does Ahri, Inquisitive give all units -2 or target one unit?
If you Ambush a unit into combat after Ahri's legend ability has already resolved on your other attacking units this combat, does that ambushed unit avoid her -1 Might trigger since it's a triggered ability?
If an Inferna ambushes in during combat, is it affected by Ahri legend? Also, if Blue Ahri is defending into a Deflect unit, can I choose not to apply the -2 to avoid paying the Deflect cost even though the wording does not say 'may'?
Diana's player moves into a battlefield where Ahri Inquisitive and another unit are present. In response to Ahri's When I attack or defend trigger, Diana plays Star-Crossed Lovers targeting Ahri and a unit in base. Does Ahri's -2 Might still resolve, or does removing her prevent the reduction? Does Ahri Inquisitive's -2 Might resolve if she is bounced before resolution?
A follow-up discussion asks why one champion's ability targets while another similar legend ability does not, specifically comparing legend versus champion wording about enemy units. Why does the blue champion target enemy units while the green champion does not?
