5e changes things, which YOU argued when YOU said demigods can only be children of gods and mortals. You don't get to argue out of both sides of your mouth. Find me a quote that says planetouched exists if you can.
I'm not arguing outside of both sides of my mouth. Planetouched were only an organizational tool to put similar mechanical options with similar origins in the same box. Those options still exist. They have remained largely unchanged in origin.
Demigods were a power level and are now just the children of gods and mortals. Planetouched were a group that included Aasimar, Tieflings and Genasi who find their origin in extraplanar roots. Teiflings, Aasimar, and Genasi still exist, and they still find their origins in extraplanar roots. Nothing about that has changed, the only difference being that they didn't see a point in making an organizational group for them, since they were so scattered over three different books.
No plane touches any of them, or ever has. They have the blood of fiends, celestials, etc. in their blood. "Planetouched" was just a poetic way to group the various races with bloodlines from planar creatures.
If you want to see it that way, sure, and that poetic device is still true. Tielfings still have the blood of fiends, Aasimar still have the blood of Celestials, ect. So, if nothing has changed, why are you declaring that something must have changed?
You don't need to disprove. You need to prove. You need to prove your claim that races with no connection in 5e(they are all listed as separate races) are suddenly all one race.
And how am I supposed to do this when you have provided no defintion of race or subrace? I did my best with my previous examples, but you declared that sharing genetic material doesn't make you of the same race, then you declared that canonical origins for tieflings and Aasimar actually make entirely new beings that don't even exist in 5e.
You have refused to define the terms, that way you can alter them at a whim to continue declaring yourself right.
Talk to a new player and mention martial, and yes they will be confused.
Unless they have ever heard the term "Martial arts" or "Martial Law" or any of the million of other places that this word is used that would make it a fairly obvious term.
Because it's a ridiculous supposition. There aren't any like that. It's not as if any of them have celestials, fiends or whatever as parents.
Except in the example I gave they literally did. So again, you seem to just ignore my posts and respond to strawmen because that is more convenient for you.
So first, we're talking PC races here. Second, devils, celestials an demons all have blood. Third, so what. This response is just a Red Herring of my point. It doesn't matter how many races don't have blood. All the ones that do would still be "bloodtouched" if we go with your logic.
So, first, no we are talking about "races" I never once said that I was limiting this discussion to playable races. Especially since any race is playable.
Secondly, can you prove that devils, celestials and demons have blood and not ichor, bile, sap or some other fluid?
Thirdly, if it doesn't matter and you don't want to discuss it, why bring it up? As a category it could exist, if you wanted to define creatures on that line. I won't dispute that. Does that make them all the same race? I don't know, you haven't defined race yet so I would have no way of knowing if it would match your definition.
Show me such a grouping in 5e, which is the edition under discussion here. 5e changes things, so you need to prove it under 5e rules.
So, we immediately pivot from you being wrong that they weren't being grouped together in 3e to you suddenly demanding I provide the same grouping for 5e.
But again, because Tieflings were in the PHB, and Aasimar didn't come out officially til years later in Volos and Genasi were first introduced in the elemental evil companion.. they've never actaully all shown up in the same book.
Additionally, not having a stated official group doesn't make the group not exist. For example, "Playable Small Races" is a group that exists. There is no category name for them, but they certainly exist and can be discussed. Generally we do so by saying "small races". Therefore, since the planetouched do exist, and planetouched still means the same thing... then there is no logical reason to assume that it doesn't exist as a category.
