First up, the RAW. This is pretty simple: Divine Sense works on celestials, fiends, and undead. Player characters are all humanoids (see page 11 of the PHB), and the Tiefling traits do not say anything about making the character a fiend in any way.
Next, we have the lore. In 3.5e, tieflings were the descendants of actual fiends, whereas in 5e, they are ...
Yes, a tiefling can have two human parents
Borrowing from my question What's the difference between a Tiefling and a Cambion?
From Xanathar's Guide to Everything, we have this table on page 62:
1-4 Both parents were humans, their infernal ...
While it may not be "game breaking", it is unbalancing enough that it is disallowed for Adventurers League play (same as the Aarakocra PC race, which also grants flight):
All sidebars and optional rules in the Sword Coast Adventurer’s Guide are legal for D&D Adventurers League play with the exceptions noted below.
The following rules options are ...
Such a character can't cast augury, barring some kind of magic item or homebrew
Augury is a 2nd-level spell. It is not a tiefling racial spell, as you noted, nor even a warlock spell.
The Sword Coast Adventurer's Guide and Mordenkainen's Tome of Foes add a number of other tiefling variants with different racial spells - but none of them get augury as a ...
No material specifies that they cannot, nor any mechanical effects or penalties for a tiefling that is mutilated in such a fashion. The DMG, on page 272, includes an optional rule about lingering injuries which has examples including severed limbs. For instance, losing an arm:
Lose an Arm or a Hand. You can no longer hold anything with two hands, and you ...
Here is what flight does: it makes the player character immune to certain types of monsters. For example if the party gets attacked by bears, or wolves, or lions, or tyrannosaurs, your tiefling variant can fly into the air and now the monsters can't hurt him.
Usually this is not a huge problem, because the monsters can still hurt the rest of the party, so ...
The rules are quite clear (emphasis mine):
[...] If you are able to cast spells, you can't cast them or concentrate on them while raging. [...]
[...] you can cast the hellish rebuke spell [...]
So by the rules, you are not able to cast any spells independent on what kind of action and components they need as ...
Paladins in D&D 5e don't have to be of good alignment.
Firstly, even in earlier editions of the game, a tiefling could be of any alignment, even lawful good, and become a paladin. In D&D 5e, it's even easier as there are no longer any alignment limits or racial restrictions on any character class.
In particular, the Oath of Vengeance paladin (PHB ...
OK so let's be honest - these "Virtue Names" are basically like choosing Smurf names, and tieflings are way more emo than Smurfs. So listed "Virtues" include normal positive things we'd normally think of as virtues, but also things we wouldn't necessarily pick for a brainstormed list of virtues IRL, like torment, weary, creed, and despair. And, as you ...
Casting Hellish Rebuke when raging is not possible.
If you are able to cast spells, you can't cast them or concentrate on them while raging. (Player's Handbook, page 48, under Rage)
The casting time or source of the spell doesn't have an impact here - a raging barbarian simply can't cast spells at all.
They do not stack because the damage roll of Flames of Phlegethos is separate from any spell's damage roll
The first bullet of Flames of Phlegethos states:
When you roll fire damage for a spell you cast, you can reroll any roll of 1 on the fire damage dice and use the new roll.
And thus it can only apply to damage rolls of spells you cast. The other ...
By RAW, the Paladin's divine sense gives them the ability to sense celestial, fiend or undead beings (PHB 84, "Divine Sense"). Tieflings are not fiends - they don't have the "fiend" keyword, specifically - and thus are not able to be sensed by the Paladin's ability.
It's always a tiefling offspring.
The PHB, in the section on tieflings says (emphasis mine),
Their appearance and their nature are not their fault but the result of an ancient sin, for which they and their children and their children's children will always be held accountable.
Based on that, I would say a tiefling/human pairing would result in a ...
There are no rules that prevent this. Furthermore, there's no in-fiction reason that would prevent a DM from having a world where this is possible.
In most fictional worlds, as in the real one, one person is the product of many bloodlines:
Public domain image (source). Click to enlarge.
A Tiefling has at least one bloodline that is derived from an ...
XGtE is optional
It's important to remember that most of XGtE's content comprises optional rules, and this particular section on character generation is no exception. In fact, the opening on page 61 explicitly states:
IDEAS, NOT RULES
Even though these pages are full of tables and die rolls, they don’t make up a rules system — in fact, the opposite ...
In D&D lore, there are indeed tieflings of races other than human. The stats in the Player's Handbook represent human-tieflings, but this does not preclude the possibility that there are others. Ultimately, the tiefling's human-centered nature is a leftover from AD&D 2nd edition, which was considerably more human-centric than later versions of D&...
Almost human, with a variety of fiendish traits.
Before D&D 4th edition, tieflings were simply the descendents of humans and evil extraplanar beings, such as demons or devils. 4e retconned them to be humans who had acquired devil-like features in a pact for power with Asmodeus.
When tieflings were introduced in AD&D 2nd edition, they ...
Warlocks with fiend pacts are mortals,1 and therefore do not have any relevance to any fiendish hierarchy—in life, anyway.
Fiend-pact warlocks are rather likely to find themselves on the Lower Planes after death, either because they actively enabled an evil entity to advance its aims on the material plane and thus are judged evil themselves, or because ...
The quoted sentence is not enough to imply that the the chance of manifesting the taint starts low, or that the chance of an individual getting it increases with latter generations. In fact, the chance of it manifesting can go down significantly over time and still make that sentence true. Let's look at an example.
To simplify the math, let's imagine that:
It depends on your campaign
The strength of any kind of damage depends on the campaign. While Sparksbet mentions the resistances from Monster Manual in this question - it matters a lot less than it seems. You are not using every monster in the Monster Manual. You are not even randomly picking monsters from the monster manual using an uniform distribution (I ...

I wouldn't. A tiefling is a humanoid, not a fiend, and therefore escapes the notice of Divine Sense. #DnD https://t.co/JXoB4gK7iU

Short answer: Cantrip's damage is affected by character level, no matter their origin.
Not-too-long answer: Cantrips increase damage as you gain character levels, as the description of Vicious Mockery explains. Since Devil's Tongue doesn't give any extra rulings in this regard, it's safe to assume that the damage increases as you level. In fact, the ...
It depends on the campaign, for the "Is this balanced?" question.
I will focus on that in my last section, comparing your race to similar other races.
It's hard to say if features like Flight will be balanced without playtesting it. But, as can be seen in this question, the major problems dwell in early levels. While essentially granting a slower Fly spell ...
You can't gain the favored class bonus unless you are taking a level in it. That means if if you have a level in Paladin and take levels in Oracle, you still cannot take the favored class bonus for Paladin, only Oracle.
The favored class ability does still apply to the Oracle's lay on hands however, if you had taken it before.
There are a couple novels which reference tiefling children, one being the Neverwinter sub-series of the Drizzt series (Elf + Tiefling = Tiefling) and the Brimstone angel series:
Prior to Asmodeus's ascension to godhood, the infernal blood could be diluted through intermarriage, but afterward, the union of a tiefling with another race always produced a ...
This depends on which type of damage you change it to.
When it comes to Hellish Rebuke, different monsters are resistant or immune to different types of damage, and some types are more often resisted than others, which could make your altered versions of the spell more or less useful. According to this answer, which accounts for the monsters in the 5e ...
Yes, a Tiefling can be a Paladin (and Tieflings don't have to be evil)
In general, there is no restriction on any combination of race, class, and alignment in 5th Edition D&D. The very first editions of D&D did restrict Paladins to only being humans, but that restriction was abandoned by 3rd edition, and any race could take up the mantle of a ...
Tiefling tails look pretty flexible, but they probably don't have much fine control over them
The books published so far (for 5e, at least) seem pretty thin on description of tieflings in the detail you want. By searching, the most I could find that referenced the tiefling's tail is the default description given in the Player's Handbook (pg 42):
The Spell save DC would include the proficiency bonus.
Player Handbook (p.205)
The DC to resist one of your spells equals 8 + your spellcasting ability modifier + your proficiency bonus + any special modifiers
A special modifier would be a bonus from a magic item for example.
