 Most die rolls in Dominions 5 involve one player rolling higher than another player using the DRN system. To give players some idea of how likely something is to happen, here is a table that shows the difference between two values on the left, and the chance of beating that value using two open-ended dice on the right. Most die rolls in Dominions 5 involve one player rolling higher than another player using the DRN system.

 What does this mean? It means that if you have a Jotun Moose Rider with attack skill 9 and your opponent has an Abysian Infantry with defense skill 10, your chance of beating him with two openended dice (and thus scoring a hit) is 38%. If the values were reversed, your chance of success would be 54%. Why the seeming disjunction? Because the “zero-point” is only 46%. Remember – the table shows the chance of beating your opponent. Thus, if you are evenly matched, you need to roll higher than he or she does on the same type of dice, and thus your chances of doing so are less than even. 46%, to be exact.  What does this mean?

 Sometimes the manual will state that a given effect requires a morale check (or some other ability check) “against” some number. This is simply a way of saying that a unit’s morale (or other ability) + DRN is compared to the stated number + DRN. So if a unit has to “take a morale check against 12,” this means the unit’s morale + a DRN is compared to 12 + DRN. If the unit has a morale of 10, the chart above would indicate that the chance of this unit passing the check is 30%. Sometimes the manual will state that a given effect requires a morale check (or some other ability check) “against” some number.

 +===== Rolls for success =====
 +A common situation you'll find yourself in is trying to win one at least one of a series of particularly difficult rolls, such as trying to get a [[Soul Slay]] cast through the [[Magic Resistance]] of a [[super combatant]]. Here are a few values to orientate yourself around what to expect:
