Essence 20 (Power Rangers) Dice Roller

I'm trying to make my own macros for attacks since the official character sheet has some issues. I'm at a bit of a loss on how to approach this since Essence 20 rolls have a lot going on. Essentially each roll is a d20 plus a skill die (d2, d4, d6, d8, or d12). The skill die can then be up shifted or down shifted to the next highest or lowest skill die. The dice shifting mechanic is something I have no idea how to handle. The d20 can also be affected by edge and snag (advantage and disadvantage from 5e) Another bit that's wonky is criticals occur when the skill die rolls its highest number as opposed to the d20. I'd appreciate on any help or advice on how to approach this. Thanks.

bumping as I would like it for the GI Joe game as well.

I'd recommend giving feedback on the sheet in it's forum thread . Based on some tests with the sheet, the Essence system just has too much going on to handle with a generic macro. It needs either an API script or the custom roll parsing of the sheet. EDIT: You could make a macro that would handle edge/snag and shifting the skill die for non specializations, but constructing the ladder is where it gets beyond what a macro can do unless you want to hardcode in the ladders.
