Hello,

Had a question about Grenades or explosives in general and i could not find the answer.

When tossing or activating a explosive. IN between two opponents, how do you determine the range of the explosion???

ENgaged/SHort/Medium??? LONG for bigger explosions??

Grenades "blast range" would be engaged. So those two opponents you mention would need to be engaged with each other.

[EDIT] I believe thermal detonators break this rule... something like short range.

First off, there's not really a "blast radius" for grenades in this system. You throw a grenade, you select a single target, and you only deal damage to that target.

However, if you are able to trigger the Blast quality, that's how you deal damage to opponents other than the initial target. Typically the weapon will make note of which range band the Blast quality works, with most of them defaulting to Engaged; I think only the Thermal Detonator is the exception, and its Blast quality hits targets that are out to Short Range from the initial target.

And if you can't trigger the Blast quality, then mechanically there's no explosion. Narratively it could be described as the explosion going off too far away to affect anyone but the primary target, or if the damage was enough to kill the primary target, that they jumped on the grenade and thus absorbed the blast, killing themselves but protecting their comrades.

The Blast quality is activated by spending 3 Advantage, that's on p.155 of the Core Rulebook. The default range is all characters Engaged with the original target. I couldn't find any examples of equipment with larger blast ranges. You can activate Blast even if the attack Fails. I couldn't find any examples of equipment with larger blast ranges. Edit: The Thermal Detonator does affect every character within Short Range of the original target if Blast is activated.

A Success with 3 Advantage would represent putting the grenade in the optimum place to injure everyone.

A Success without 3 Advantage would represent only being able to get the original target in the blast, either from a poor throw or a quick reaction from the others.

A Failure with 3 Advantage would represent the idea that "close counts with horseshoes, hand grenades, and tactical nuclear weapons". Edit: The Thermal Detonator is, effectively, a tactical nuclear weapon.

A Failure without 3 Advantage would represent a malfunction, or a throw that goes so wide it is totally ineffective.

House rule, I'd say that if two targets were at Short Range from each other, a character could aim at a point in between them (this point being Engaged with each of them to allow Blast to work), by upgrading one Difficulty to a Challenge.
