Boss Battle with 4 Phases

[JEIA_CORP]

I'm making a boss battle with multiple phases. So far I have when he (the boss) gets down to half HP, he shifts phases.
After that, it won't let me shift again using the When Enemy HP is __% command because it still thinks the first phase is the only enemy.
Advice?

Never mind I got it.

@JEIA_CORP In case someone else has the same query, it would be nice if you would post the solution.

When creating a boss with multiple phases, make sure you give the first phase a large amount of HP.
This is because it will still be the bosses HP even after it changes phases.
Use the When Enemys HP is Certain% below 100% and select the Transform action.
Then choose the next phase of your boss.

The transform action keeps the remaining HP of the target so you all really need to do is create 4 separate enemy IDs that have identical HP, preferably the total combined HP of all 4 phases, and transform them when needed. Unless they are supposed to be entirely different enemies on different phases with different HP pools, in which you simply had to use a recover HP command to heal them back to full when the next phase starts.
