[Spell] Making a channeled healing spell

[cm15]

Hi all,

I'm trying to make a channel spell which heals the target over time and drains the casters' mana. My first instinct was to try to adapt siphon mana but the best i can do is to transfer HP to a friendly unit (i.e. the caster is losing HP over time instead of mana).

Is there something I'm missing? Or will I have to resort to triggers for the desired effect?

Thanks in advance

I believe this will need to be triggered. Look on here in the spells section someone may have this done already. I have a doom heal in my sig but it does not remove mana over a period of time but you are welcome to edit it if you want to use it. The config is in GUI but the triggers are in JASS.
