And something else to warn you about Honor mode.
It is not just traps and fights that can go wrong.
Here is example what can go wrong
In my game I allocated points to Jahan to raise his Hydro skill to 4 at level 12. Only to learn later that spells which require level 4 are locked until character level 15. So I wasted the points there pre-maturely.
Honor mode is able to load a save if you catch the mistake on time. But because it is single save file, it may overwrite the save file and then you screwed.
