Yes. I posted it already. I thought you had read it.Let's say I agree with you for a second. Point #5 "Gains no benefit from magic resistance because there is nothing in the effect's description that would include it in the type of magic that can be dispelled, anti-magiced, or resisted by magic resistance."
This right here tells me that there is a type of magic that can't be dispelled, resisted, yadda yadda.
"You might be thinking, “Dragons seem pretty magical to me.” And yes, they are extraordinary! Their description even says they’re magical. But our game makes a distinction between two types of magic:
• the background magic that is part of the D&D multiverse’s physics and the physiology of many D&D creatures
• the concentrated magical energy that is contained in a magic item or channeled to create a spell or other focused magical effect
In D&D, the first type of magic is part of nature. It is no more dispellable than the wind. A monster like a dragon exists because of that magic-enhanced nature. The second type of magic is what the rules are concerned about. When a rule refers to something being magical, it’s referring to that second type. Determining whether a game feature is magical is straightforward. Ask yourself these questions about the feature:
• Is it a magic item?
• Is it a spell? Or does it let you create the effects of a spell that’s mentioned in its description?
• Is it a spell attack?
• Is it fueled by the use of spell slots?
• Does its description say it’s magical?
If your answer to any of those questions is yes, the feature is magical."
Maybe.So, a Revenant;s Vengeful Glare is magical...
It may or may not be magic, but it doesn't fit any of the categories listed in the official clarification that would make it a spell or spell-like effect. Therefore if it is magic, it is of the first type of magic that is "the background magic that is part of the D&D multiverse’s physics and the physiology of many D&D creatures."but it is not #magical#gamemechanictag.
You can't dispel a dragon's ability to breath fire and you can't resist being hit by it using magic resistance or gnome cunning. You can half the damage from fire breath if you have fire resistance.
You can't dispel a revenant's ability to paralyze and then frighten a target and you can't gain resistance to being hit with the effect using magic resistance or gnome cunning. You can however be resistant or immune to being paralyzed or frightened and mitigate the effects of this monster's ability in that way.
According to the sage advice, if the description of the ability says it is magical, then it is a spell or spell-like effect and it can be countered, dispelled, yadda yadda.And so, being listed with "magical" in the text only applies if it is a type of magic that can be countered, dispelled, anti-magicked or resisted by magic resistance.
Not being listed as magical in the text (or not specifying that it is equivalent to a particular spell, or not calling it a "spell attack," or not using spell slots, or not being cast from a magic item) means that it is either not magical or it is the type of magic that is inherent to the physics of the world or to the physiology of the creature and it can not be effected by anti-magic game mechanics.However, not being listed as "magical" in the text does not mean it is not magical. Because there are types of magic that aren't tagged "magical" because they are too diffuse to interact with the game mechanics.
I'm not going to say it's beautiful game design, but they have laid out their intent pretty clearly.
