Rules for damage from forced movement.
inspired by MCDM
When a creature would be forced into the space of another creature or object, both take damage and potentially absorb movement.
If the impacted object or creature is two or more sizes smaller than the moving creature, and not fixed in place, it is harmlessly shoved aside or prone.
If the impacted object or creature is within one size category moving creature, both targets take 1d6 bludgeoning damage and the remaining forced movement is reduced by 5 feet. This damage is then repeated for each 5 feet until either target is reduced to 0.
Size difference. When a moving creature would be forced into the space of an object or creature that is two or more sizes smaller than it, and is not fixed in place. The impacted target is harmlessly pushed aside or knocked prone without reducing the remaining movement. If the movem
Moving through creatures and objects. If the impacted target is reduced to 0 hit points as a result of slamming damage, the moving creature then continues moving for the remainder of the forced movement.
Resilient Objects and Creatures. The DM may decide that some creatures or object cannot be moved through, regardless of the damage they take from moving creatures. For example, robust cave walls or solid iron doors are unlikely to be significantly harmed by moving creatures.
For these objects, they do not take damage from being impacted by moving creatures. The creature stills takes damage from slamming into these objects based on the remaining movement. The movement is always eventually reduced to 0.
Version 2
simplest use of existing rules but does mean tracking object hp and that damage movement will rarely surpass 1d6
Slamming into other objects and creatures
When a creature would be forced into the space of another creature or object, treat the moving creature as if it fell the remaing distance (including the rules for falling onto another creature). An impacted object also takes the same damage the moving creature (before any resistance or reactions).
If the impacted target is reduced to 0, the moving creature keeps moving for the remaining movement reduced by a number of feet equal to the damage taken by the impacted target.
The DM might decide that an impacted object, such as a thick stone wall, would never take significant damage from moving creatures and, as such will not bother tracking its hit points and the moving creature always stops moving.
Examples:
Adam the fighter is thrown 30 feet. He flies 10 feet and then impacts a fragile wooden table with 6 hit points. The remaining movement is 20 feet, the DM rolls 2d6, dealing 9 bludgeoning damage to both Adam and the table. The table is reduced to 0 and destroyed. Adam keeps moving, the 6 damage absorbed by the table reduces the remaining movement by 6 feet to 12 feet.
Optional Rule: Shove Slams
When a creature use the Shove action to force a creature into the space of another creature object that is the target's size or larger, the moving creature can be treated as if it was forced 10 feet for the purposes of damage.
