ToME: the Tales of Maj'Eyal

I would like to propose an addition to knockback: if the subject of the effect hit an unwalkable tile (wall/tree/etc.) it will be stunned for a number of turns equal to the remaining tiles it would have travelled. If it seems ovepowered to make it the general rule maybe it could be fine for a specific skill, for example for the brawler and his push kick.

I wouldn't say a stun, but bonus damage if the monster got knocked into a wall or other monsters. A little bit like Push kick works now.
