Talk:Modifying Dice/@comment-191.85.33.110-20180105025403/@comment-454133-20180105061811

Adding or subtracting the number of dice in your hand before the initial roll is not dice modification. If Jan Ors lets you roll 4 dice instead of 3, that works even against Omega Leader. This is what is meant by "adding or subtracting the number of dice that are rolled".

After the initial roll, you'll be left with some number of dice results (hits, focuses, crits, blanks on red; evades, focuses, blanks on green). However, adding a Hit Result (which is adding dice results) is dice modification. So is rerolling a die, or changing one result to a different result. These are blocked by effects that don't allow dice modification, such as Omega Leader.

Cancelling dice is not modification. For example, when you cancel hits with evades during the Compare Results step, you can cancel dice that are protected from modification (e.g. by Emperor Palpatine). Crack Shot and Accuracy Corrector are other example effects that cancel dice.

I hope that helps!
