roll:tldr:4caee

This command is likely used in a tabletop or role-playing game and involves rolling a series of dice to generate a sum.

Here is a breakdown of the command's syntax:

• "roll" is the command keyword that initiates the dice rolling process.
• "--sum-series" is an option or flag that specifies to calculate the sum of the rolled dice series.
• "${3{2d5}}" is the expression that represents the dice rolling series to be calculated.

Breaking down "${3{2d5}}":

• "${...}" is an indication of an expression that needs to be evaluated by the command. It specifies the number and type of dice to be rolled.
• "3" indicates that you need to roll three times.
• "{2d5}" specifies the dice to be rolled. "2d5" means rolling two 5-sided dice. So, in total, there will be three sets of "2d5" rolls.

For example, if the two 5-sided dice (d5) rolls result in 3 and 4 on the first set, 2 and 1 on the second set, and 5 and 3 on the third set, the sum of all three sets would be 3+4+2+1+5+3 = 18.

The command will calculate the sum of all the rolled dice sets based on the provided expression and return the result.
