Beautiful painting and great concept. What do you mean when you say that you've converted d6 into 3d6?
Well we took a break from Warmachine and came back down to the Underhive about May (after several years spent on the surface
).
We decided we wanted better ruleset than straight from the rulebook (which aren't very exciting actually) so game after game we were adding new stuff to make gaming more demanding and cool - especially after few beers
One of mods was changing range attack d6 rolls into 3d6 - it's more-less like: old 4+ to hit on d6 is now 11 or 12+ on 3d6 (forgot exact number). More dices adds elment of statistic to the game. And of course we also had to change to-hit modifiers to fit new rules better.
