Ability and Skill Checks

Ability Check

Roll a D20 and compare to relevant Ability Scores. The Player wants to roll under the relevant Ability Score, but above the GM Difficulty.

Skill Check

The same roll and mechanic as an Ability Check, with an extra rule:

If a Character has points in a skill related to a skill check, they get to roll a bonus die based on their level in that skill:

d4>d6>d8>d10

Then roll both the d20 and this bonus die and choose the best for the result.
