If target hp less than "x" = exori gran ico

I want a script that if target (creature) hp < "x" , use Exori Gran Ico ( i want "x" amount to be 300hp or something that i can edit )
and preferably use Exori Gran Ico if theres only one creature around, 1sqm from me


OBS: I'm NOT asking for a script that use spell when creature HP Percentage is lower than "x"

bump.

I have forgot if you can use $target.hp but try it!

auto(200,300)

if $target.hppc == 'Swarmer' and $target.hp < 300 then

	if cancast('exori gran ico') then

		cast('exori gran ico')

	end	

end

yeah, doesn't seems to work, i don't think you can use target.hp then... but thanks anyways for answering
