## Explain dX and YdX Syntax[edit]

Can somebody explain what does d10 or 1d10 mean?

For example, Weapon does 2d8 damage.

Posible meanings:

1) damage = random number between 2 and 8, i.e. damage = rand(2..8)

2) damage = maximum number of two randon numbers bwteeen 1 and 8, i.e. damage = max(rand(1..8),rand(1..8))

3) it does 2 damage at distance 8

- # of dice then sides of dice. so 1d10 (or just d10) is a 10-sided dice. 2d8 is 2, 8-sided dice, ect.--Name Violation 06:08, 3 March 2010 (UTC)

- To clear something up, 1d10 and d10 are NOT the same. The former explicitly says to roll a ten-sided die one time. It literally means "the sum of rolling one time a ten-sided die." The latter is a reference to a ten-sided die outside the context of how many times it should be rolled. It is literally means "ten-sided die." Examples: A ranger uses a d8 (eight-sided die) for his hit die. A 5th-level ranger has 5d8 (the sum of rolling five times an eight-sided die) hit points. —Sledged (talk) 15:29, 3 March 2010 (UTC)
