In 8.3 Visions patch we get a corruption value for our personal stats. When these values reach certain break points they have different effects. Such as when you have NET 40 corruption you can spawn a "thing from beyond" which follows you. A WA that would target this issue wouldn't need to load unless your net corruption was 40. An example I considered was a variation of the Algan WA that shows an arrow / plays a sound when the mob spawns.

** Other solutions **
I also considered something like a 2nd trigger where Item Equipped Corruption -> Value could be useful as well.

Additional context
Adding corruption info available for WA to make conditionals on could be useful down the line as well. Not sure how just yet...

We in general don't add support for features of a expansion that are likely only temporary, as the whole adding, deprecating, removal dance is a lot of hassle.

For corruption I even doubt the general usefulness of a load/conditon option. A custom trigger sounds entirely reasonable for that and would be as performant as a load option.

Maybe that'll change if there's lots of demand for complicated auras that have to take corruption into account, but I doubt that.
