More often than you'd imagine. That is why a lot of demi-humans were taking thief as one of the component of their multiclass. Then when max level was reached in a class, the demi-human would often use a wish to wave the limit by one at a time! It was as simple as that. All you needed was the following:Honest question - how many times have you had a player hit the level cap on a demihuman character and then keep happily playing along with no possible chance to advance or gain hp? Because I find this scenario really, really hard to wrap my head around.
I have plenty of firsthand experiences of playing demihumans in various 1E games. Generally, the level limits were rarely an issue because, as we almost always started at 1st level, most games were done well before anyone came to a level restriction.
In the handful of cases where this actually happened (I.e. hit the level cap), tge level cap rule was always house ruled away to maintain peace at the table.
1) The spell magic jar so that the M-U casting the spell would do so from your body. And thus it would be your body that would age.
2) A ring of regeneration in case the age effect would kill you. Regenerating would keep you from dying from the system shock.
3) A high enough mage willing to cast that spell for you.
4) A DM fair enough to allow this.
It was a great money sinker, an excellent reason to keep adventuring and an easy plot advancement to keep the players going.
