some questions

[Requiem]

1. Does water resist rock in this game. Whenever I use a rock move against water it always says that it's not very effective

 

2. Why do I hit like a wet noodle? A stone edge from my lycanroc should have one shotted the opposing mamoswine but it didn't even do half. I EV trained my mon 252 in attack

Typing are default unless changed by the field.

 

Also who were you fighting that had a mamo, and where?

are you fighting on an icy (or snowy mountain) field? rock attacks are part-ice there making them resisted by both Water and mamoswine's Thick Fat

 

(also mamoswine has really good physical bulk I definitely wouldn't be expecting most neutral attacks to ohko)
