Any way to reset hero to single profession?

I tried using search but it don't seem to work, is there any way to reset a hero profession back to single, ie koss choosing a secondary prof lowers hps didn't want to do that.

I haven't actually noticed any change in HP for changing secondary professions or taking a secondary profession. Do you have some proof for that? It seems that it would be quite a game-breaker if it really happened.

What the heck? That is complete rubbish, add a 2nd profession doesn't lower the HP in any case and form.

Only thing that effects health is skills, conditions, effects and runes with negative HP.

The base stats of ANY character is always:

Health will be 480 at level of 20.
Energy capacity will be 20 at level of 20.

Not sure what gave you the idea that having a 2nd profession lowers your health?

To answer you question you cannot change a hero back to a single profession once you changed to two. But there no reason for 1 profession anyway!

Second profession has nothing to do with total health whatsoever. Did you put any major or superior rune on Koss?

To the basic question. No.

2ndary profession does in no way lower health.

Got your answer, so I'm closing.
