But then it would take longer to defeat the two side monsters, but if you have a strong Darkness attack, you can deafeat both of them with one/two attack instead of taking two turnes. Like, two dark KNights will destroy both side monsters in one of thier turns, hopefullyright behind each other while your alchimist can just use mega potions or revive and whatnot while if you simply have one gunner doing damage, it will take a lot longer to defeat him
