Reminder, once you kill an (S)EG (whether your own or a shared one), you can encounter a new one. So the one EG you cause to flee could give one SEG and 3 more EGs to continue the encounters. So I do find both potions and elixirs to be of no use once your friend list starts getting properly populated.
