I'm looking to make an ability where if you use it, you deal 2/3/4/5x of the unit's damage. I tried using Frost Arrows with GDD like I would for autocast spells that add damage like DotA's Glaives of Wisdom or Impetus. I can't just use the unit's base damage + unit's main stat since it might have items that give it bonus damage rather than just stats.
Any suggestions?
