I'm breeding a male Vanillite with Ice Body with a Ditto to try and get a Vanillite with Snow Cloak. (Not a hidden ability) Is this possible or am I wasting my time? Ive got a box full with them all having Ice Body.
From gen VI (X) onward if a male or gendarless Pokemon breed with ditto or a female Pokemon it has a 80%(60% for HA) chance of passing down it's ability. So that means you have a 20% chance of getting a Pokemon with random ability that means the hatched venilite will have snow cloak chance is 20%/2=10% and it will have ice body chance 80%+(20/2)=90%. So your success rate of getting a snow cloak venilite is 10%. Hope I helped.
