Help

Is there a way to write a macro so that it comes up with a roll based result? Like it rolls a d4 and on 2-4 it rolls damage and on a 1 it says fail? My 5e party is making grenades and explosive ammo using gun powder, but I don't want it to work every time due to it being a very crude system. 

There is - what's the damage of the grenade? Logic statements do not exist, so you have to do something a bit messy like this: &{template:default}{{name=Grenade Attack}}[[[[ceil(([[1d4]]-1)/3)]]d6]] {{Throw=$[[0]]}} {{Damage=$[[2]]}}

Was thinking of something like 2d8 force damage with a 75% chance to actually explode. There is an Artificer in the group, so the odds are better than average of it actually going off.

Righto, probably a bit more like this then: &{template:default}{{name=Grenade Attack}}[[[[2*ceil(([[1d4cs5]]-1)/3)]]d8]] {{Mechanism Roll=$[[0]]}} {{Damage=$[[2]] force damage}} or you could display [[1d4-1]] for the mechanism roll, that way it would be an angry red 0 for failure: &{template:default}{{name=Grenade Attack}}[[[[2*ceil([[1d4cs5-1]]/3)]]d8]] {{Mechanism Roll=$[[0]]}} {{Damage=$[[2]] force damage}}
