Would you be able to find or define what, for you, would be the difference between a Clever Exploit and an Abusive Exploit? However you define it?In my experience, many -- possibly even most -- players have a bit of the exploiter in them, just waiting to find the right unintentional synergy in the rules. The primary difference, as I see it, is that a cheater is embarrassed or apologetic when caught, while an exploiter can't wait to show off their "accomplishment." I take great pleasure in letting them finish their explanation before declaring that it doesn't work the way they think at my table.
For example, back in the day, we used to give +2 / +10% to stealth checks for people underground or in stone buildings if they had a stoneskin spell active. The idea being that the spell had their skin adopt a stony appearance. It also meant that they would need to be nude, or nearly so. Did it come up? Well, at least once, obviously, and one or two times after that. It was a highly situational advantage.
