Does anyone have specific rules they use to determine a skill check's difficulty class for players?
I've been using this rule of thumb:
- DC 5 = Very Easy
- DC 10 = Easy
- DC 35+ Extremely Hard
However, this doesn't really work as players level up.
Specifically, I've got a player with a fighter (level 14) that has a +26 Intimidate. Granted in most cases he is going to pass his intimidate check, but I need a good scale for things.
I originally thought of doing this:
- Easy = Must roll 5 or higher (regardless of skill ranking)
- Medium = Must roll 10 or higher (ditto)
- Hard = Must roll 15 or higher (ditto)
- Very hard = Must roll 18, 19 or higher
However, this doesn't always cover every scenario. If my fighter wants to intimidate a black dragon, that might scale based on level, the dragons intelligence, etc.
This could also apply to Disable Device and other checks.
I know the most common answer is going to be "Determined by the GM", but I like using formulas for things to make it simpler and easier for larger campaign calculations.
Is there a formula that you use that would make this a bit easier to figure out?
