5e Effect help?

[The Scriven One]

This is a long shot, but I figured I'd ask.

I also hope this isn't confusing. It's really late, but I had the idea and I wanted to see if it worked. So far, no.

My setting has places of power. Each place of power has a signature of promoted energy types/effects ranked 1-5, with an equal and opposite negated type of energy/effect. So in one area, necrotic effects are enhanced, while, say, fire effects are hindered.

Characters have a personal signature and countersignature, based on level, that has the same range, but applies somewhat differently. For anything that is signature for a character, I'd like them to add their Rank to checks related to those attacks. I'd also like to let them add their Rank to Saves versus anything that they negate- their countersignature. I'd like a character with say a fire Countersignature of 3 to give a penalty to various actions taken against them by any creature with a fire Signature.

The only thing I can think of, which I've been playing around with, was to create conditions called "FireSig" or "NecroticCount" and another condition named SigRank, along with a CountRank condition.

This is the part I'm clueless about- is it possible to put a variable number into SigRank and CountRank, and then use it in the FireSig Effect? So for example, if a creature's CountRank was 3, and they had the FireCount Effect defining an interaction with FireSig, could I then place a variable penalty to attacks equal to CountRank and vice versa?

If so, how? If not, it was a long shot anyway.

If somehow this is possible, I'd also like to reduce or increase SigRank and CountRank relative to a Place of power's Signature or Countersignature as signified by a condition I place on characters when they enter an area.

Thank you very much in advance.

There's no mechanism for custom conditional tags in the effects system. Something of the type you are describing would have to replace the effects system with one that supports what you need. It would take a fair amount of custom extension work, and it would need to be updated whenever the effects system changed.

I guess you could just add the modifiers manually with the modifier box or make an effect for each skill/ability you want to modify. Not as good as having one catch-all effect but it might work

Thanks. I figured as much, but I wanted to make sure I wasn't missing something obvious.

I think we're just going to have to do that. Fortunately, places of power are somewhat rare, and personal signature/countersignature interactions are reserved for encounters with major NPCs and monsters.
