I noticed a few other threads have kombo lists so I decided to make one for shinnok considering right now he's my best character.
In Impostor: Right now my go to combo is 1,1,2, DF2 MB at last hit, Dash, 1,1,2, DB1 This combo hits pretty hard but it's a little advanced to pull off. I've actually done it fully once in a live game so far but it gives you your stolen power so it's nice. Also depending on who you steal from the power is really really good with mixups.
ANY: Same lead up just ending with DF2 instead of DB1. I hit this combo for 31%
I'm not very good at the game and these are pretty basic kombos. But I figured i'd create a thread to help considering we don't' have one for shinnok yet.
