A ruby dice roller
require 'dice'
Dice.roll('1d100') # => 57
You can also add static modifiers
Dice.roll('1d100+5') # => 57+5 # => 62
And you can modify the dice rolls them selves by dropping the highest dice result
Dice.roll('3d100dh') # => [57, 14, 88] # => [57, 14] # => 71
Dice.roll('3d100dh2') # => [57, 14, 88] # => 14
Or dropping the lowest dice result
Dice.roll('3d100dl') # => [57, 14, 88] # => [57, 88] # => 145
Dice.roll('3d100dl2') # => [57, 14, 88] # => 88
