Do Pokemon with the Slip Through ability use a different formula for damage calculation that only uses BP, Pokemon's Attack Stat, STAB, Weakness/Resistance, and Defending Pokemon's HP?
Method of Testing: Compare the damage output of a Mischievous Heart Erufuun and a Slip Through Erufuun with Energy Ball. These Erufuun should have the same nature boost for SP.ATK and a similar IV (+- 5 points I'd say). Test on the same pokemon when doing this to avoid error.
Edit: To be slightly more blunt: Does Slip Through completely ignore the defending Pokemon's attack stat when attacking?
Also, do Power Items still "carry over" IVs in the daycare like in HGSS?
Policy Question: Would is be wise to put the tests of things proven in the OP? (i.e. have the link to the video/post that is supposed to prove/disprove it)?
