For the archer template, would be lot better to have bushido on him for maximum luck. Question: if u embrace honor, and u attack something, does everything else attack u then? Or just the creature u attacked? Might be a way to pull it off, kill sidespawn first, then honour Leviathan and finish him off...?
Unless they changed honor, you honor a monster and that is it. It does not immediately attack you. You still have to engage it in combat. Other spawns will still attack you naturally. Attacking something else will break your sequence in the honor attack (the more consecutive hits the more damage you do). You cannot honor anything injured (if leviathan uses bless you can't honor him until that damage is healed). You can switch back and forth between different monsters. You can use ranged melee attacks, magic, and summons/pets, but you will not gain as much honor when you kill the beast. You also won't gain as much honor if you get the first attack on the monster. If the monster gets to hit you first you will gain honor. Honestly, just honor whatever you attack and play as if you were fighting it normally.
