[Spell] Using HP to restore mana

[Superfrycook]

I need to create a custom spell to use HP to restore mana, TY.

Do you want it to be % or flat, can the Hero die from sacrifing life for mana? Level scaling? LUA, JASScode, GUI?
Some extra details would be for sure helpful the good news is this should be fairly easy to make.

EDIT:
Here is a simple spell using flat values, since it runs instantly there is no need for any fancier things.

DoomBlade's way will work but here's how I implemented it in one of my maps. I based it off the Channel ability and I called it Life Burn. Burns 10% health to generate equal points in mana. Casting below 10% health can kill the hero. Higher ranks decrease cooldown and mana cost. I used this icon and added this sfx as Art - Caster in Object Editor. Currently the only benefit of going up in rank is a slower cooldown. Not sure this is the most fun way of doing it for players.

• Life Burn Cast
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Life Burn (E)
  • Actions
    • Set VariableSet pyro_burnt_PN = (Player number of (Owner of (Casting unit)))
    • Set VariableSet pyro_burnt_hp[pyro_burnt_PN] = ((Max life of Knight_Hero_Var[pyro_burnt_PN]) x 0.10)
    • Unit - Set life of Knight_Hero_Var[pyro_burnt_PN] to ((Life of Knight_Hero_Var[pyro_burnt_PN]) - pyro_burnt_hp[pyro_burnt_PN])
    • Unit - Set mana of Knight_Hero_Var[pyro_burnt_PN] to ((Mana of Knight_Hero_Var[pyro_burnt_PN]) + pyro_burnt_hp[pyro_burnt_PN])

I basically do the same thing for my "Cup of Blood" item in my map (but I have jass functions to show mana-text (my heal-text function does not work with negative values when I did this, so need to do it manually)).
AND I allow the hero to die and spawn a demon if that happens...

• CupOfBloodOnUse
  • Events
    • Unit - A unit Uses an item
  • Conditions
    • (Item-type of (Item being manipulated)) Equal to Cup of Blood
  • Actions
    • Set temp_unit = (Hero manipulating item)
    • Set temp_point = (Position of temp_unit)
    • -------- +hp --------
    • Unit - Set life of temp_unit to ((Life of temp_unit) - 125.00)
    • Floating Text - Create floating text that reads -125 at temp_point with Z offset 80.00, using font size 8.00, color (50.00%, 75.00%, 25.00%), and 25.00% transparency
    • Floating Text - Change (Last created floating text): Disable permanence
    • Floating Text - Change the lifespan of (Last created floating text) to 0.65 seconds
    • Floating Text - Change the fading age of (Last created floating text) to 0.50 seconds
    • Floating Text - Set the velocity of (Last created floating text) to (128.00 + (Random real number between 0.00 and 32.00)) towards (75.00 + (Random real number between 0.00 and 30.00)) degrees
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Life of temp_unit) Less than or equal to 0.00
      • Then - Actions
        • Unit - Create 1 Clicky Daemon [Boss 4 Summoned] for Player 9 (Gray) at temp_point facing Default building facing degrees
      • Else - Actions
        • -------- +mana --------
        • Custom script: call RestoreManaWithText(GetTriggerUnit(), 225.0, 1.2)
    • Custom script: call RemoveLocation(udg_temp_point)

Is it Real, Integer, or Boolean?

Simpler way without trigger is by using the Scroll of Restoration ability and just have negative values on the amount of health restored.

Is it Real, Integer, or Boolean?

Managain = real variable
Level = integer variable

Thats all you need for this.
Using indexing and whatnot for a spell that runs trigger instantly is redundant.
