I am a little late in replying, but here is a list I made for you of Skills and in what situations their bonus is applied.
Agility: used for various traps and geographic conditions
Aware: used when testing Petrify, Surprise, and various traps
Bravery: used when testing Fear
Dodge: used when testing Fire, Freeze, Stun, Web
Escape: used when Adventurer attempts to Escape from combat and also to Block Escape of Monsters
Locks: used for tests of Locked Doors and Treasure Chests
Lucky: used when testing Petrify, casting spells, scrolls, and various traps
Magic: used when casting spells and scrolls
Strong: used when trying to open Jammed Doors, lift or move traps and obstacles, swim, climb, etc.
Traps: used for various traps, including Trapped Doors and Treasure Chests
Additionally, World Builder adds these skills, which are fairly self explanatory:
Fishing, Haggle, Hunting, Riding, Survival
I made the following as a quick reference which I update as my adventurer’s characteristics (Str, Dex, Int) as well as Skills improve.
Surprise: Int-10 + (Aware) = _____ [F: Mon Atk]
