Questions about RPG Damage Engine.
The practical details behind the request, access and result.
Can RPG Damage Engine help me balance my D&D 5e boss fights?
Yes, it lets you see how much damage a boss deals over multiple attacks and what the odds are of your party surviving. It helps you ensure the fight is challenging but fair.
Does it handle advantage and disadvantage?
Yes, it can calculate how those mechanics shift your average damage and your success rates for specific dice rolls.
Can I use it for homebrew weapons?
Absolutely. You can input any damage expression and get the stats for it instantly, making it easy to balance your own unique gear.
How does it help with elemental resistances?
It applies multipliers like 0.5x for resistance to the final damage calculation, giving you an accurate look at how defenses work.
What kind of dice does it support?
It handles standard TTRPG dice like d4, d6, d8, d10, d12, and d20, covering almost all common gaming systems.
Can it tell me the range of a damage roll?
Yes, it gives you the minimum, maximum, and average for any expression you provide, so you know the best and worst case scenarios.
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.
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.
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.
