Level 5
Jun 5, 2015
Help Please, how do I create Spell Lifesteal?
Example there is a Lich that cast Frost Nova for 300 damage, how to make 25% of the spell damage converted to health for the Lich?
Please post triggers In GUI. Thank You.
If you don't want to trigger the damage from your Frostnova by yourself.
We need a DDS (Damage detection System) for example this one:
GUI Damage Engine v3.6.0.1

to the Triggers:
  • Frostnova cast
    • Events
      • Unit - A unit starts the effect of a spell
    • Conditions
      • (Ability being cast) Equal Frost-Nova
    • Aktionen
      • Einheitengruppe - Add (Triggering unit) to FrostNovaUser
  • Frostnova cast end
    • Events
      • Unit - A unit stopps casting
    • Conditions
      • (Ability being cast) Equal Frost-Nova
    • Actions
      • Einheitengruppe - Remove (Triggering unit) from FrostNovaUser
  • Frost Nova dmg
    • Events
      • Game - DamageEvent becomes Gleich 1.00
    • Conditions
      • IsDamageSpell Equal True
      • (DamageEventSource is in FrostNovaUser) Equal True
    • Actions
      • Unit - Set life of DamageEventSource to ((Leben of DamageEventSource) + (DamageEventAmount x 0.25))
