Any of the above types may have additional fields from mods. `reason.from` will be `mod` or `engine`. `modifier`: when true, the function should return the actual `hp_change`. Note: modifiers only get a temporary `hp_change` that can be modified by later modifiers. Modifiers can return true as a second argument to stop the execution of further functions.
