This mod adds a command that lets you damage entities however you want.
requires fabric & fabric api: https://fabricmc.net/
example-
[ ] = required
( ) = optional
{ } = optional with certain damage types
/damage [target entities ] (damage type) (amount) {source entity}
/damage @e minecraft:Generic 5.5
/damage @e minecraft:Arrow 20 @s
With projectile damage types I remade the damage handler for projectiles so that a real projectile is not required.
If a mob dies from a damage command with a player as a source it will drop xp as if it was killed by the player.
