Event checking if player has potion effect

[success009]

after doing that some research I made this script

on potion effect added:
if player has permission "member.wizard":
execute console command "effect clear %player% minecraft:slowness"

Problem with this is this only works if I use command to give the player effect
This doesn't fix the problem with the splash and drinking and tipped arrow.

I tried looping every second but that takes too much load on server and doesn't even work for effects like harming

Is there a way to provide immunity of negative effects to a specific group of player which have specific permissions?

every 2 seconds:
    if player has permission "member.wizard":
        execute console command "effect clear %player% minecraft:slowness"

should stay updated and not cause a lot of lag, you can change the timing to what fits your server best

on join:
    if player has permission "member.wizard":
        
        async run 0 ticks later:
            while player is online:
                remove slowness from player if potion effects of player contains slowness
                wait a tick

SKBee required.

Will do an async loop so "wait a tick" isn't a problem.

Thank you for you guys help
but After some more research I found a better approach

on entity potion effect modification:
    if event-entity has permission "member.wizard":
        if event-entity is a player:
            if event-potion effect type = poison or darkness or slowness or weakness or mining fatigue or wither or hunger or levitation or unluck or nausea or instant damage:
                cancel event
                send action bar "&aMagic has prevented &c%event-potion effect type%&a!" to event-entity
