When are attacks considered ranged

[majulen]

when using a weapon like blunderbuss how close to no longer consider it ranged (is their any indication of this on the battlefield or character information?)

[Boeroer]

It's always considered ranged - no matter how close you get. So abilites that are restricted to melee will never work with a ranged weapon. An exception is Backstab. There you have to get <= 2 meters with a ranged weapon.
