FAQ
Questions RPG Damage Engine owners ask.
- 01
What damage expressions can I parse?
You can use standard dice notation such as 1d8+4 slashing or 2d6+3 fire. The engine parses the quantity, die type, modifier, and damage type.
- 02
How do critical hits work?
The engine supports D&D_5E (doubling dice) and PF2E (doubling the final result) rules. You can specify these using the critRule parameter.
- 03
Can I calculate the chance of killing a boss?
Yes, by using calculate_encounter_probability, you can input your attack damage, number of attacks, and the enemy's HP to find your success probability.
