Spawning particles randomly around the player

[Tr3nd1ngT0p1c]

Basically im trying to make it so a certain piece of armor spawns a cool looking effect around the player but in a singular particle pattern.

on player armor change:
    wait 1 tick
    if player's chestplate is leather chestplate:
        set {cp1.%player's uuid%} to true
        wait 1 tick
        loop blocks in radius 3 around player:
            add loop-blocks to {_b::*}
            set {coords} to random element of {_b::*}
            wait 1 tick
            if {coords} is set:
                play 1 dust using dustOption(blue, 2) at location {coords}

this is what I got and it spawns particles 1 at a time but at the players feet but I cant seem to make it spawn the particles randomly around the player.

I used this for one of my past projects, hope it helps. (Uses SkBee in case you do not, even tho it seems you are)

every 0.5 second:
    loop all players:
        loop-player is {MER}
        chance of 10%:
            play 10 of falling water above loop-player offset by vector(0.5, 0, 0) with extra 0
        chance of 10%:
            play 10 of falling water above loop-player offset by vector(0, -0.5, 0) with extra 0
        chance of 10%:
            play 10 of falling water above loop-player offset by vector(0, 0, 0.5) with extra 0
        chance of 10%:
            play 10 of falling water above loop-player offset by vector(0.5, 0, 0.5) with extra 0
        chance of 10%:
            play 10 of falling water above loop-player offset by vector(0.5, -0.5, 0.5) with extra 0
