I'm writing a roleplaying game based on the Gumshoe system (I swear this is a language question rather than one for rpg.stackexhange.com!).
Characters in this games have a set of Investigative Abilities and a set of General Abilities.
The two sets of abilities function in very different ways and have very different purposes, and in playing the game previously, there was some confusion because they're both described as "abilities" despite featuring different rules.
Investigative Abilities are things like forensic science, evidence collection, research - things that allow the characters in the game to find clues. They always succeed.
General Abilities are things like driving, fighting, pick-pocketing - things that don't in and of themselves lead to clues, and that also might fail.
Is there a better way of describing these two sets of abilities that more clearly delineates them?
