Why all the hassle with Mullich? Empty prisons, tavern bans, right-click reveals, etc... Why not just change his specialty to +350 gold? It solves all the problems with one action. Or am I missing something, and changing the specialty is more complicated than with Ione or Serene?
I don't see any particular hassle. In one case, and in the other, one line of script is added. It's clear that this method is also kept in mind as an alternative.
Just better not to give him gold, but wood, or pikemen specialty.
Giving a pikemen specialty makes sense for one of the regular knight heroes. But Mullich only appears in the dungeon. The specific specialty isn't particularly important in this case.
