Hi All!
The advantage of a hidden weapon is obvious in a non-combat situation. The rules of hidden/concealed weapons are almost clear at the surprise round. But what about the in-fight rules? The rules state that any fighting combatants are aware of the others. What about the hidden weapons? My rogue has a visible short sword in his right hand and a hidden dagger in his left hand. My enemy fights with my teammate 25 ft away. Range and ranged attack into melee penalties doesn't matter now. Can I throw my dagger and cause sneak damage?
