I have already finished all my bosses attacks but i need a way to keep track of the attacks and phases. I was thinking that i could just do a repeat until and then a pick random and send a message for the attack i want to do but some attacks break if i message it while its attacking so i need a way to exclude attacks that are currently being used.

Could you link the project?
I used variables for my boss game, I made a “roll” var and I made it pick random 1 to 4 every 10-15 seconds. Then, the bullet sprite linked to my boss would do a certain attack if the roll was a certain number.
EX:

if <(roll) = [1]> then
do something
end

If you want to keep track of the phases and attacks, you could just make a variable for the phase and the current attack. The roll i mentioned previously would do well for that, since it is a variable and you could keep track of it by just showing it and looking at what attack is currently playing.
For phase, just make a phase variable and whenever the boss reaches 0 health or something set the phase to whatever phase it's going to next.
TL: DR: use variables

Hmm… you're using list blocks (and my game uses purely variables for attacks) so I do not know how to help you. Someone who knows how to use list blocks better than I do should. Sorry for the inconvenience, I wish you good luck on your game!

If you are using a list, you could simply remove the attack from the list when it is triggered, then add it back again after said attack is done playing.

So I'm making a boss and I want the boss to have phases with different attacks. I don't know how to activate different phases using health because I want phase 2 to trigger when his health is at 400, phase 3 to trigger when he's 300 until he eventually gets to zero and it ends. If anyone knows how to do this, PLEASE tell me.

This might help,

if <<not <(phase) = [3]>> and <<not <(phase) = [2]>> and <(bosshealth) < [401]>>>then
set [ phase] to [2]
end
if <<not <(phase) = [3]>> and <(bosshealth) < [301]>> then
set [ phase] to [3]
end
