Macro for Empowered Magic missle

Good day folks, I am currently trying to get a macro set up for a CL 7 Wizard casting Magic Missile. I have it set up as: /em casts magic missile! [[1d4+1]], [[1d4+1]], [[1d4+1]], [[1d4+1]] This would work fine if i didn't have it as empowered. I would need my 1's=3, 2's=4, 3's=6, and 4's=7. I've been looking at the dice reference page but havent found anything that could help me do this.

[[floor((1d4 + 1) * 1.5)]] for each missile. 

sweet, thanks.

If you want to get a little fancy and make it an option you can choose each cast: /em casts magic missile! ?{Empowered?|No,   [[1d4+1]] • [[1d4+1]] • [[1d4+1]] • [[1d4+1]]   |Yes, [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]] } Or can even fancier with it by having an option to cast it against one person, multiple targets, one person with empower, or multiple targets with empower: /em casts Magic Missile! ?{Casting Type?|Single, [[1d4+1 +  1d4+1 +  1d4+1 + 1d4+1 ]]  |  Multiple,  [[1d4+1]] • [[1d4+1]] • [[1d4+1]] • [[1d4+1]] | Single(Empowered),  [[floor((1d4 + 1) * 1.5) + floor((1d4 + 1) * 1.5) + floor((1d4 + 1) * 1.5) + floor((1d4 + 1) * 1.5) ]] | Multiple(Empowered),   [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]] • [[floor((1d4 + 1) * 1.5)]]   }
