The fight can quickly mean the end of your Honor Mode. As far as I know, barrelmancy no longer works there or backpacks with explosives, as the Apostle only takes limited damage from it and can no longer be killed like that. A few pieces of advice that you should perhaps take into account, depending on how you want to fight the battles yourself, some of them could possibly be a savior in an emergency.

- you don't have to fight against Kethric with the right conversation selection.
- Scratch is always the best boy with the "Help" ability. He likes invisibility potions.

- Scrolls are good, 1-2 fire elementals take care of the Necromites on the side.
- The Mindflyer should be noticed by someone who can kill him instantly.
- A bottle of water can make a difference in the fight... in combination with chain lightning
