How do i handle If a mini want to shoot at an enemy mini locked in close combat with a nother mini?
Might already be mentioned in the rules but i cant find anything cleare about it.
You can't use ranged weapons in close combat. If you have no melee artifact you can always use improvised attack ehich give you none of the gear bonuses.There is no minimum range for ranged weapons.
Unsure if you could Charge with a ranged weapon. The action says "rush into close combat", which could be ranged weapon. The bonus section says "+1 for charging (only melee)"
I see no reason why you should be able to fire a pistol in close combat. A flame thrower might be a little more tricky, but better keep it simple. As a houserule I could imagine, that you could only attack the connected model and not being in touch with one, but attack one on the other side of the table.
