1st Ed. D&D question (or HackMaster v4.)
I was about to ask what happens when a character's ability scores fall below the minimum for a class. Do they lose the class?
i.e. If a Magic User becomes too stupid to be a Magic User (e.g. Int falls below 9), do they cease to be a Magic User? If the Wisdom falls below 9 do they cease to be a Cleric.
I couldn't actually find a rule outside of initial character creation minumums.
Then my attention was drawn to the ability table for Wisdom in HackMaster and they listed chance of spell failure for scores below 9.
