 The notation has the form of '''''n''d''y''''', where ''n'' and ''y'' are variables:
 *''n'' is the number of dice rolled
 *''y'' is the number of faces on each die
-For example, if an article states that a [[weapon]] has a [[damage]] of 1d24 (''roll one die with 24 sides''), it can do a damage between 1 and 24. If an article states that a weapon does a damage of 2d24 (''roll two dice with 24 sides each''), it can do a damage of (1..24) + (1..24).
+For example, if an article states that a [[weapon]] has a [[damage]] of 1d24 (''roll one die with 24 sides''), it can do a damage between 1 and 24. If an article states that a weapon does a damage of 2d24 (''roll two dice with 24 sides each''), it can do a damage of (1..24) + (1..24). When calculating potential damage from hit dice, hitmu(mhitu.c) sets the attack's base damage to ndy, then mhitm_ad_phys(uhitm.c) adds the weapon damage.
-If ''n'' is omitted, it is taken to be 1.
+An additional notation that can be encountered is '''''n''d''y'' &times;2''', for the [[double damage]] property. For example, [[Grayswandir]] has 1d8 &times;2 +(1d20) damage. This means that a single die roll of 1d8, plus enchantment, is multiplied by 2; the die is not rolled twice. The 1d20 is added to the result of the multiplication.
 Some cases, such as calculating the amount of conditions to be cured by a [[unicorn horn]], will use the result of one or more rolls to determine how many sides will be on a die used for a subsequent roll. For example, a blessed unicorn horn will cure (d(2d4) &minus; 1) ailments. Two four-sided dice will be rolled and their values summed, then a die with the number of sides equal to the prior result will be rolled, and finally one will be subtracted from the result. This produces a range of values weighted toward lower results.
-== Probabilities ==
+==Probabilities==
 {{randomvariable|name=d(n,x)|graph=3d6.svg|caption=[[wikipedia:Probability mass function|Probability mass function]] of a roll of 3d6 and [[wikipedia:probability density function|probability density function]] of the normal distribution with the same mean and standard deviation.|distribution=[[Wikipedia:discrete uniform distribution|uniform]] (n=1)<br/>[[wikipedia:triangular distribution|triangular]] (n=2)<br/>approx. [[wikipedia:normal distribution|normal]] (n>2)|mean=<math>n(x+1)/2</math>|stddev=<math>\sqrt{n(x^2-1)/12}</math>}}
 Rolling a single die gives any possible roll with equal probability, but multiple dice will tend to give many rolls in the middle of the range and few at the ends. Therefore, rolling 3d6 is not the same as rolling 1d16 and adding 2, even though both give a range from 3 to 18 and a mean (average) of 10.5.
