More spell help please

ok so not to give away my spell i will not use its name or ability so if your thinking why would you want a spell like that then now u know...

i want a ultimate spell that say for example puts a needle in someones arm the at MY will i can activate that needle to heal them

how would i go about making this spell (lets call it) "hypodermic"

btw i already have a dummy spell set up (holy light) so how i do it?

p.s i presume it must be done by triggers???

thanks 4 any help :dance:

cud u just replace the unit, like when the spell is cast replace the existing unit witha unit with the needle attached to it then just have that unit being healed and when the spell stops or the needle is removed replace the unit back

im not the best with spells but its just my little input

i got past that bit i just disabled ability"a" and gave ability "b"

then when abilty "B" used i diabled it and enabled "a"

the problem is this...

how do i get it to remember which unit i cast it on (as too heal it at will)

Have you tried saving the target unit as a variable? That would mean that the "needle" would disappear if the original spell was cast on another unit, however.

you could use an array with the unit's ID (the 4/5 number code after unit's name)

That way the unit would always be remembered (i think)

u could edit shadow strike to deal 0 damage but the buff damage will then heal the by using negitive damage of course u couldnt choose when the buff would activate....

Pirogen you ans was the one im looking for but how do i actually do it? (whats the trigger?)

what happens is the spell "hypodermic" is cast then the spell is removed and replaced with another called "inject"

so what would be the trigger to make it so when i cast "hypodermic" it adds target unit to a variable (you know what i mean its 5am in the morning here)

then whats the trigger (if you can be bothered) to cast "inject" on the unit?

thanks for all the help so far.....
