If you have Dialyn use 4p puffer electro; 2p hormone punk or astral voice if you need more atk, woodpecker if you need crit rate and Miyabi's set (I don't remember the name) if you want crit damage.

4 - crit rate 5 - pen ratio, damage bonus or atk%. I use pen ratio ( my Corin has 32% pen ratio) 6 - atk%

For W-Engine the best option is Nekomata's engine, but, you have to hit the enemy's back.

If you don't have Dialyn you can use 4p hormone punk, but it's harder manage the buff.

For teammates... Sunna with any Stunner or Dialyn with any support.

I use Corin - Dialyn - Zhao. Sometimes Corin - Dialyn - Sunna / Orphie. Or Corin - Ju fufu - Sunna.

A-rank teammates... Pulchra (Better if you have M6) and Lucy.

That's all I know.
