Immolation damage based on attributes

[arielavi]

I've searched and I can't find anything related. I don't even know where should I start: I wanna make an Immolation spell that consumes mana to damage nearby units. The problem is: I wanna burn 1% of total mana per second to damage an area based on a hero's strenght.

Any tips? Should I use issue orders? Or spell events?

Add the unit into a unit group when it acquires the ability.

Periodically pick units in the group. For each picked unit, pick units in range and manipulate their stats.

If your spell is the active Immolation, I'd suggest using the spell cast for it.
You would need to use a timer and periodically check the unit for the Immolation buff to reduce mana and damage nearby units with group enumerations.

This is simple spell and can be done with basic knowledge of how the World Editor is working. There are a lot of tutorials that can fully help you create the spell some of them even include test maps. Yet here are some tips:
When the casting unit cast the spell set it to caster (variable) then create another periodic trigger that will run every X seconds to do your actions. The actions are as follow. Set unitgroup (variable) unit around the caster (variable) within XXX range. Pick every unit in unitgroup (variable) and apply the damage that you need to be done. Set the mana of caster (variable) to his current mana -1% of his maximum mana (for how to calculate % of a number refer to the local school). The check if the caster (variable) have enough mana if not deactivate the spell and order the caster (variable) to deactivate immolation. Play around the editor and search the "Google" he is not bad person just you must not be afraid of learning basic knowledge. Have fun creating your spell.
