Doing a very thorough patch soon so I appreciate the feedback. Push has been one of those things that is immediatly intuitive to teach during play but Ive really struggled to put concisely into words.
When you push an enemy they move 1 space away from you. The three available spaces are the space opposite you and the two spaces orthogonally adjacent to that space.
There is no agi roll on push or followup. Only roll agility rolls for the move action and things that tell you they are (as the move action) like charge or impetuous.
Thank you for buying and I hope this clears things up. You can also ask about rules and find pick up games on the discord!
