Calculated Risk is a small Foundry VTT module for D&D 5e that shows your chance of success before you roll.

Settings
Settings are under Configure Settings --> Calculated Risk.
You can choose whether players see exact percentages, simple labels like Likely or Risky, or nothing at all.
Calculated Risk can also pull AC from a targeted token.
Hidden numbers
Some numbers are filled in for the player, like a target's AC or the DC on a spell save button. The Hide filled-in numbers from players setting decides whether players see them:
- Match D&D 5e's visibility settings (default): a DC stays hidden whenever D&D 5e hides it on the chat card, and a target's AC stays hidden unless D&D 5e shows AC on attack rolls.
- Always hide: players never see a filled-in number.
- Always show: players always see it.
When a number is hidden, players see where it came from, like the creature's name. Players can still type their own number instead. The GM will always see all values.
