In the past, Acid Armor was only available by breeding a Goomy/Sliggoo/Goodra with a Skrelp who knew it, but there's no Skrelps in this game (as far as I know, haha). Are there any Pokemon in S/M that I can breed with Goomy to obtain this egg move?
Skrelp is the only Pokemon that can breed Acid Armor onto Goomy. Like you said Skrelp is unobtainable in S/M, so you will just have to wait for Pokemon Bank to be release for S/M.
