Sources of Temporary Negative Levels

[HalifaxDM]

So in reviewing the Energy Drain ability and the rules for negative levels, I noticed this line in the PRD regarding negative levels:

PRD wrote:

A creature with temporary negative levels receives a new saving throw to remove the negative level each day. The DC of this save is the same as the effect that caused the negative levels.

With the energy drain spell and the energy drain ability the negative levels become permanent after 24 hours if the Fort save is failed and with the enervation spell the negative levels do not last long enough for this to come into play. With raise dead a permanent negative level is gained.

As far as I know, these are the primary sources of negative levels.

So is anyone aware of any sources of negative levels that remain temporary indefinitely until the save is passed?

This is neither a complaint or rules query ... just a matter of personal curiosity. :-)

Holding a holy weapon when you're evil (and unholy if you're good, etc) gives you a negative level until you put it down. There's some other aligned items like that.

The witch's Summon Spirit Grand Hex gives her a negative level until the summoned ghost is dismissed.

Soul Drinker is interesting in that it gives the ability to bestow (apparently permanent, though I'm not entirely sure if they are meant to be) negatives levels with a touch attack as a standard action.
