Example, sense motive to catch a lie might be spot (catching facial ticks) + listen (hear stress in voice). A pc with high spot might catch the lying npc, a pc with high listen might catch them, but a pc that's not especially high in either might get a clue via spot, then confirm things via listen.

What this script does is combine the values of two skills, and then check them against a DC like a normal check. You do generally need to set the DC higher to account for the fact that a combination of two skills are being checked.

Derived skill check.
Instead of a straight skill check we're going to check something based on a combination of two skills
