[Trigger] autocast question

[raid1000]

so i see these descriptions on items like "gives a 15% chance to cast spell x on attack" how does that 15% chance work?

It is an item orb ability. It is slightly bugged thou so it may fire more than or less than 15% of the time (atleast one of the orb abilties).

• Events
  • Unit - A Unit is attacked
• Conditions
  • Level of *your ability* equal to 1
  • Random integer number between 1 and 100 less or equal than 15
• Actions
  • Set temppointA = (Position of (Attacking Unit))
  • Unit - Create 1 *dummy* at temppointA for (Owner of (Attacking Unit))
  • Unit - Add *your spell* to (last created unit)
  • Unit - Order (last created unit) to *whatever spell*
  • Unit - Add a 2 seconds general expiration timer to (last created unit)
  • Custom script: call RemoveLocation(udg_temppointA)

Shall work.. be sure to set the ability's manacost which you give to the dummyunit to zero
