In Numenera, players can apply effort to increase their chance to hit with an attack and/or to increase the damage of the attack.
Thus far, my group has been playing that they can apply the effort to increase damage after making the attack roll and thus knowing that it has connected. I get the feeling however that maybe the players would need to declare before rolling what effort is being applied to the attack and/or damage for the attack, but I can't find a clear ruling in the book. Which scenarios correct?
