Make a spell or item have a chance to cast a spell such as frost nova. Like i want a passive spell to have a 20% chance of casting frost nova on striking or something like that.

Please help and thanks in advance.

Unit - A unit Is attacked
Conditions

You can do that, but just for ease of implementation I suggest using the Lightning Orb or Black Arrow Bonus spells. These are under items. Now you will create the Frost Nova you want fired then go and make the spell based on Black Arrow(name is actually Item Attack Black Arrow Bonus). There are 3 fields you want to fill in
-Chance to Hit Heroes
-Chance to Hit Summoned Units
and
-Chance to Hit Units
You just fill in the percentage you want and there you go, nice fast and no triggers
