I think you need to trigger that and as far as I know that's impossible in GUI. And since I don't know JASS I'm afraid I can't help you.

You can modify an max life+ gaining item ability to unit ability and add this to your hero while casting spell X. but you cannot change that to a %.

Can you still increase HP if it's at maximum? Hehe. Is this a healing spell or just increase hero's HP pool?

There is a buggy but effective way to do this. Set an integer to the unit's max health, divided by 100, multiplied by 30. As long as the life isn't one HP, it won't bug.

Then add that integer every ten seconds.

But that wont show that the unit has more hp
I think you should be able to use the JASS system Bonus:

use skills based on item skill hp bonus, having ten levels each, giving 1000, 100, 10 and 1 hpper level and set the levels. Note that this way it gives the bonu s over a constant hp maximum, changing the base wont change the bonus, exept you make additional AI that matches increasements.
