Coding question

[Markd102]

My character has a Periapt of Wound Closure, which amongst other things, doubles hit dice rolls (5E).
Does anyone know how to either code an effect, or alter the actual hit dice math to accomplish this?

We just do it manually. You could write an extension for this, of course.

Roll the hit die. Then drag the result into the HP field. This heals you that amount twice: once on the roll, once on the drag.

You'd need an extension to actually double it on the roll.

Also +heal effects don't work on hit dice. Not sure if that is intended or a bug.
