Cloyster SW's Spine Missile

[ZAKtheGeek]

If you choose the same pokemon twice with this attack, does it take 20 damage twice?

If so, then if you have a Double Rainbow attached to Cloyster, does it do 10 damage twice, or do you first add up to 40 and then reduce by 10?

20 damage each time, for a total base damage of 40.

In the case of DRE, you would apply the -10 damage to the total base damage of 40 - for a total of 30 damage.
