Better Effect

[pearl gate]

Hello!! I'm looking for a mod or way that improves and adds onto the /effect command, as I've run into a few problems with it. First off there is that it takes in seconds instead of ticks, which is annoying but not the worst- What really is annoying is there isn't a way to add/remove from effects, like making an effect last 5 seconds longer or such.

I'd like to know if there is any way or mod that allows for this, as the only solution i can think of is making 100s of predicate checks

You can add to the length of an effect, by reading the nbt, adding to it in storage and using that as a macro to set the new length.

You can get the duration in ticks using area of effect clouds iirc. Not sure about the specific method - but like most things, there is a hacky data pack way xd

Oh that would be great, just a small limitation is that that i'm 1.20.1, and iirc macros were introduced in later versions. Thanks a lot tho !

I think you can do everything through area effect cloud

you can get durations of ticks via apply mob effect in enchantments

set it to the saddle slot, on tick, then remove
