 ===== Vehicles ===== ===== Vehicles =====
  
-(Paolo, Work in Progress) Issues: how to treat passengers; tidy up. 
  
- +This vehicles ​rules are meant to replace and improve the mounted combat rules. ​Dnd5 rules do not cover vehicles well and mouting rules have few issuesif mount and rider have different initiative fights can be impossible; intelligent ​mounts ​cannot be ever be controlled; the reach when riding ​is unclear...
-Vehicles ​rules are meant to replace and improve the mounted combat rules. ​Vehicles are creatures (possibly constructs),​ but depending on the vehicle they are basically normal mounts or a second skin just like Druid Wild Shapes. +
-Vehicles that behave like a second skin and protect the driver fully (exactly as a Druid Wild Shape) or partially à la Shield Guardian. +
- +
-We call this kind of vehicles**mounts**, **fully enclosing**,​ **partially enclosing**. E.g., dragon, a hovering bike, or a flying skateboard are mounts; ​a Mecha can be a fully or partially enclosing vehicle depending on the model; a war tank is a fully enclosing vehicle. +
- +
-If the vehicle allows to use larger weapons we convert the dice following the tableThe damage changes are inspired by the Spell Enlarge/​Reduce. +
- +
-For example, let us think to a Large Mecha robot with a Battleaxe. Battleaxes normally deals 1d8 damage (1d10 two handed), in the hand of the Mecha the Large Battleaxe will deal 1d12 or 2d8. +

-We remove the size limitation as some Sci-Fi mounts would be probably smaller than their rider, for example a flying ​Skateboard ​would be probably a Small creature able to carry a Medium rider. As usual particular beats general, this rules are meant as default.+We remove the size limitation as some Sci-Fi mounts would be probably smaller than their rider, for example a flying ​skateboard ​would be probably a Small creature able to carry a Medium rider.

-Normally, we assume all characters have an universal driving license. ​But in case of difficult ​driving a check may be requiredIn this case if you have the Vehicle Proficiency you can add your proficiency bonus.+Vehicles are willingly creatures (possibly constructs) that can be controlled by pilot inside them or controlled by a rider on them. 
 + 
 +Riders are not protected by their vehicle, but they enjoy increased speed. Pilots instead are fully or partially protected by the vehicle surrounding them. 
 + 
 +The first kind of vehicles are **mount**, the second are **enclosing vehicles**. 
 +E.g., a dragon, a hovering bike, or a flying skateboard are mounts; a mecha or a tank are an enclosing vehicles.

 To enter or mount a vehicle, you need to use half of your movement and you cannot enter a vehicle if your speed is zero. For example, a Human needs to use 15ft of movement to enter or mount a vehicle. Dismount or leave a vehicle costs the same. To enter or mount a vehicle, you need to use half of your movement and you cannot enter a vehicle if your speed is zero.

-Vehicle and pilot initiative are the same: if the pilot enters, or mounts, the vehicle mid-fight the initiatives become for both the lowest of the two. If the initiative is rolled when the pilot is already inside or riding a vehicle, then the vehicle rolls for initiative and the result applies to both rider and vehicle.+pilot and its vehicle share the same initiative: if the driver ​enters, or mounts, the vehicle mid-fight the initiatives become for both the lowest of the two. If the initiative is rolled when the driver ​is already inside or riding a vehicle, then the vehicle rolls for initiative and the result applies to both driver ​and vehicle. 
 + 
 +//Similarly to the original rules, this is the only way to change initiative in dnd5, it may bring strange situations like a player that have to do his turn interleaved to other player turns or a tiny abuse to lengthen effects that lasts "until the end of the turn." However, unless gameplay proves otherwise I assume it keeps the game fun and it does not need extra rules.//
  
 When you entered or are riding a vehicle, the following rules apply: When you entered or are riding a vehicle, the following rules apply:

 ====Mounts==== ====Mounts====
   * You and your vehicle are basically two creatures sharing the same space.   * You and your vehicle are basically two creatures sharing the same space.
-  * Mechanically both use the same space, just consider that depending on the mount the rider might be in a elevated position so he needs to use a reach weapon to be able to hit. (e.g., an Halfling on a Elephant may need a lance to hit) //It appears a bit ridiculous if the rider is surroundedbut without facing rules I think it is a good compromise// +  * Mechanically both use the largest creature ​space, just consider that depending on the mount the rider might be in a elevated position so he needs to use a reach weapon to be able to hit.

But without facing rules I think it is a necessary evil.// 
-  * If an effect moves your mount against its will while you're on it, you must succeed on a DC 10 Dexterity saving throw or fall off the mount, landing prone in a space within 5 feet of it. If you're knocked prone while mounted, you must make the same saving throw.+  * If an effect moves your mount against its will while you're on it, you must succeed on a DC 10 Dexterity saving throw or fall off the mount, landing prone in a space within 5 feet of it. If you're knocked prone while mounted, you must make the same saving throw. If you succeed the saving throw you are still on the mount, but have the prone condition.
   * If your mount is knocked prone or killed, you can use your reaction to dismount it as it falls and land on your feet. Otherwise, you are dismounted and fall prone in a space within 5 feet it.   * If your mount is knocked prone or killed, you can use your reaction to dismount it as it falls and land on your feet.

   * If the mount provokes an opportunity attack while you're on it, the attacker can target you or the mount.   * If the mount provokes an opportunity attack while you're on it, the attacker can target you or the mount.
-  * You can give commands to the mount using one hand. Some creatures may require specific equipment like bridles and saddleSome creatures may receive ​commands ​in different ways, for example a Dragon will perfectly understand speech; a hovering bike won't need any special equipment a free hand is enough to give commands; a flying skateboard is controlled with the feet.+  * You can direct ​the mount using one hand. To be able to be directed properly some creatures may require specific equipment like bridles and saddlesBesides, some creatures may receive ​directions ​in different ways.

Outside what is written in this rules, mechanically //you are// the vehicle. So, for example, to direct the vehicle to do an Action you use your own Action
-  * Enclosing vehicles protects you, the exact effect depends on the vehicle. ​But when the vehicle reach to 0 hit points it is destroyed and any excess damage carries over to you. For example, if you take 10 damage in tank that has only 2 hit points left, you take 8 damage. As long as the excess damage doesn’t reduce your hit points to 0, you aren’t knocked unconscious. But you fall prone in the vehicle space surrounded by the wreck. +  * Enclosing vehicles protects you, the exact effect depends on the vehicle ​(see the next two bullet points)When the vehicle reach to 0 hit points it is destroyed and any excess damage carries over to you. As long as the excess damage doesn’t reduce your hit points to 0, you aren’t knocked unconscious. But you fall prone in the vehicle space surrounded by the wreck.

For example, if you take 11 damage in tank that has only 4 hit points left, you take 7 damage
-  * **Partially enclosing** vehicles takes half damage (round up), the other half (round down) is taken by the pilot. ​As in the previous ​example, if the vehicle has 2 hit points left and you take 10 damage ​then 5 hit points will be taken by the vehicle and will be taken from the driverSince the vehicle had only 2 hit points ​left the excess damage ​of 3 also goes against the driver.+  * **Partially enclosing** vehicles takes half damage (round up), the other half (round down) is taken by the pilot. ​For example, if you take 11 damage ​in partially open mecha, ​the mecha takes 6 damage, you take damageHad the mecha less than 6 hit points ​then the excess damage ​would go to you as normal.
   * Your ability to be heard, take any action that requires hands, cast spells or using skills is limited to the capabilities of the vehicle. Entering a vehicle doesn’t break your concentration on a spell you’ve already cast, however, or prevent you from taking actions that are part of a spell, such as call lightning, that you’ve already cast. For example, a mecha normally allows to do all kind of actions; a tank allows only to make its own attacks.   * Your ability to be heard, take any action that requires hands, cast spells or using skills is limited to the capabilities of the vehicle.

 +====Passengers====
  
-====Vehicle properties====+Up to now we assumed the driver (or rider) was the only creature on the vehicle and rules focused on the interation between the vehicle and the external world. 
 + 
 +However, depending on the nature of the vehicle there might be space for passengers.  
 + 
 +Passengers are treated at the same as drivers, but they cannot direct the vehicle and in the case of partially enclosing vehicles who takes the damage after an attack to the vehicle is randomly decided. 
 + 
 +Some vehicles may have multiple driving control posts; if two different characters try to direct the vehicle at the same time then the proper skill check contest decide witch one is understood. If the 
 +contest is a tie the vehicle understand both; what happens depends on the situation. 
 + 
 +For example: Jozan and Tordek are sitting in the two control posts of a plane. Tordek is driving and Jozan acts as a passenger. Suddently, Jozan understands that Tordek is actually a doppelganger and it is flying torward an enemy base; Jozan takes control and they do a contest skill check on Vehicle Planes to decide which one of the two gives direction to the plane. 
 + 
 + 
 +===Inside the vehicle space=== 
 + 
 +If a battle happens on a mount or inside a vehicle then it is necessary to know the exact position of each combatant inside the mount or vehicle space for it will not be enough to state that rider and mount share the space and that the driver is the vehicle. 
 + 
 +When this happens consider that the vehicle can rotate only once at the end of his turn. 
 + 
 +====Larger weapons==== 
 + 
 +Enclosing vehicles may allow to use larger weapons. To know the damage we convert the dice using the following table. The damage changes are inspired by the Spell Enlarge/​Reduce and the DMG rules about creating new monsters. 
 + 
 +For example, let us think to a Large Mecha robot with a Battleaxe. Battleaxes normally deals 1d8 damage (1d10 two handed), in the hand of the Mecha the Large Battleaxe will deal 1d12 or 2d8. 
 + 
 +^ Small/​Medium ^ Large  ^ Huge       ^ Gargantuan ^ 
 +|              |        | +5ft reach | +5ft reach | 
 +| 1d4          | 1d8    | 1d12       | 2d10       | 
 +| 1d6          | 1d10   | 2d8        | 2d12       | 
 +| 1d8          | 1d12   | 2d10       | 4d8        | 
 +| 1d10         | 2d8    | 2d12       | 4d10       | 
 +| 1d12         | 2d10   | 4d8        | 4d12       | 
 +

 **Speed**. Vehicles have the same kind of speeds of other creatures; plus few ones for Space Operas. **Space Speed** and **Hyperspace Speed**, those speeds are expressed as factor of the normal travel speed. **Speed**.

So it can use weapons, cast spells, manipulate foci... In addition of the mecha action any action the driver is able to undertake are possible via the mecha body.

Line 105: Line 133:
   * **Death-trap**. Once the vehicle is destroyed the wreck locks you. You are Prone, your speed becomes 0, and you cannot benefit from any bonus to your speed. To leave the death-trap you need to use an Action to pass a Strength (Athletics) or Dexterity (Acrobatics) check as contested by the vehicle Strength. If for any reason you have advantage (or automatic success) escaping grapples you can use the power here.   * **Death-trap**. Once the vehicle is destroyed the wreck locks you.
