Crossbows are ready to fire once per action. Reloading occurs immediately before firing as a free “interact” action, similar to drawing a sword. So you still keep a bonus action and your movement. So, yes, you can fire the crossbow once per round as long as you have ammo.
Per the official errata, “Loading a one-handed weapon requires a free hand.” This means that after errata and using Rules-as-Writed (RAW), you cannot fire unlimited two-handed crossbows in the same round.
You both need a free hand to load. Whether you’re doing this as part of the attack or as an object interaction. So the answer is no, you cannot wield crossbows two-handed then, as one hand must be available to load it as part of the attack.
So yes, Crossbow Expert needs to use Extra Attack with the crossbow, but is not required to use two attacks from two actions with Action Surge.
Yes, but ask your direct message. Certainly there is no rule that says loading must be done immediately before attacking, but depending on the level of reality of the game, it can be dangerous. An unloaded crossbow cannot misfire and in real life a crossbow that stays loaded will break pretty quickly.
When using Expert Crossbow, people typically fire the hand crossbow three times and have the other hand free to load the crossbow. In your case you want to use a heavy crossbow that requires two hands and then use a handheld crossbow but then it seems to me you would run into loading problems.
All Light Crossbow and Hand Crossbow users in the MM apply a Dexterity bonus to the damage roll. Most other Heavy Crossbow users have a +0 Dexterity mod and therefore have no damage bonus, but the Half-Red Dragon Veteran (p. 180) has a +1 Dexterity mod that applies to the Heavy Crossbow’s damage roll /p>
Does Crossbow Expert let you fire a hand crossbow and then fire it again as a bonus action? It does! Take a look at the third perk of talent. It states that if you use the charge action to attack with a one-handed weapon, you can attack with a hand crossbow as a bonus action.
Yes, a ranged attack with a ranged weapon would include your Dexterity bonus on both attack and damage rolls. The Player’s Handbook mentions this twice. You add your Dexterity modifier to your attack roll and damage roll when attacking with a ranged weapon such as a slingshot or longbow.
When you attack with your main hand (e.g. with a scimitar), the talent allows you to fire the hand crossbow as a bonus action. Only works once as you can’t load the hand crossbow with both hands.
No, you cannot load a hand crossbow while holding a shield. The Errata added a new condition to the Ammunition trait: loading a one-handed weapon requires a free hand. A hand holding a shield is not a free hand, so you cannot load your hand crossbow while using a shield.
When it’s your turn, you can use a bonus action to regain hit points equal to 1d10 + your fighter level. Once you use this feature, you must take a short or long break before you can use it again.
