Due to the additional cost of the extra apprentices (news 2460) some innkeepers
regrettably had to slash their security and personal defence training budget.
--- Out of context: as long as "rent" required the physical presence of an
innkeeper, several innkeepers had to be made ultra-strong (in some cases
stronger than a Balrog...) to ensure that they would be available most if
not all of the time. Now that the original problem has been addressed,
these innkeepers have returned to being "normal" mobs. We made a couple of
exceptions where the innkeeper has strategic importance to gameplay.
