Here's what I've come up with so far for MgT2.
Stray Shots
Determining Collateral Damage in a fight
Using Mongoose 2022 Update rules, Effect Results could determine collateral damage if a shot misses.
0
- Glancing Shot
Marginal Success: There's a chance that the shot hits something else after hitting the target. Damage to the Target could be minimal. Something gets hit behind the Target on a 2 on a 2d6 roll. 1 in 36 chance.
-1
- Near Miss
Marginal Failure: The shot misses, but barely. The target might hear the bullet whistle past or there's a sizzling sound in the air. Their hair could be blown round a little. Unless there's a blatant wall or hill behind the target, which would definitely be hit, something significant behind the target gets hit on a 2 or 12 on a 2d6 roll. 2 in 36 chance.
-2 to -5
- Complete Miss
Average Failure: The shot definitely misses. Unless there's a blatant wall or hill behind the target, which would definitely be hit, something significant behind the target gets hit on a 2, 3, 4, 10, 11, or 12 on a 2d6 roll. 12 in 36 chance.
-6 or less
- Wild Shot
Exceptional Failure: The shot goes wild. It might even ricochet off of one thing and hit another thing. Unless there's a blatant wall or hill behind the target, which would definitely be hit, something significant behind the target gets hit on a 2, 3, 4, 5 or 6 on a 2d6 roll and there's a ricochet to something else that gets hit. A 15 in 36 chance. On a 9, 10, 11, or 12 on a 2d6 roll, something significant behind the target gets hit. A 10 in 36 chance.
