I would need some definiton here ...
Bcs if nothing you "can do" is an exploit, then exploits dont exist. O_o
Blowing hundert barrels of gunpowder to kill whole goblin camp with single cantrip? Game allows it > not an exploit!
Locking NPC in dialogue and steal all his stuff with other characters? Game allows it > not an exploit!
Locking NPCs in combat and sneak through whole goblin camp, while wearing heavy armor and have 8 dex, by simply avoiding their view cones? Game allows it > not an exploit!
See what i mean?
Anyway as far as i know:
https://en.wikipedia.org/wiki/Video_game_exploitIn video games, an exploit is the use of a bug or glitch, or use of elements of a game system in a manner not intended by the game's designers, in a way that gives a substantial unfair advantage to players using it.
