So, yesterday, when I was grinding levels on my Onix in the NatDex area of Victory Road, I got in to a double battle. One of the trainers had a blissey, that used minimize twice. The fog weather condition was also in effect. I brought my rampardos, and I used head smash (and didn’t expect it to hit) but it did, and it OHKOd. How likely was that move to hit?

Head smash has 80% accuracy.

Fog multiplies accuracy by 3/5.

+2 evasion multiplies accuracy by 60%.

The resulting chance to hit is 0.288, or 28.8%.

They used minimize twice, so it’s 4+ evasion
Minimize only raises evasion by 1 in Gen 4.

Head Smash is base accuracy 80%. The fog modifies the accuracy of the move by a factor of 60%, meaning the accuracy is 80% × 60% = 48%.

Minimise being used twice means an evasiveness of +2 (it only raised the evasion by 1 stage in gen 4), which is effectively multiplying the accuracy by 60% yet again. The formula is:

base accuracy × (accuracy - evasiveness)

with any extra effects (e.g. fog) applied to the base accuracy.

The 48% accuracy in addition to ×60% from minimise results in a 28.8% chance to hit. Not so lucky after all, and sumwun was correct.

What do you mean?
My previous comment was responding to what your comment said before you edited it. Now that you edited your comment, my comment doesn't make sense anymore.
Oh! I accidentally copied something and typed the second but twice and forgot to delete the second bit lol.
@sumwun, it is 4+ evasion, becuase it used minimize twice
2 people already said that minimize raises evasion by 1 in gen 4. Why do I need to repeat this a third time?
