Sometimes the DM will want players to perform an ability check and not set a DC. They will instead use the result of the roll to give a sliding scale of success.
Example:
Two players are asked to make an ability check for Perception.
- Dave the human fighter rolls a 10, he sees webbing in the corners of the room.
- Alice the dwarf cleric rolls a 17, she also sees this and the giant spider above them.
Is there a specific name for this practice? Because everyone seems to do it (adds flavour to ability checks) but I've not seen a name for it.
