I told him no right off the bat...But he's extremely insistent about
Just tell the player "no," again; you are allowed to do that as DM
There are a number of reasons for this.
An invisible stalker is an elemental; PCs are humanoids1
The CR of an invisible stalker is 6; it usually takes 2 or 3 PCs of
level 6 to defeat an invisible stalker; the ...
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 ...
There aren’t rules for doing that: the rules offer “half-elves” (and “half-orcs”) as a race, but in both cases they aren’t mix-‘n’-match options, but static races that always offer (more or less) the same features—and whose other half, in both cases, is always human. In other words, Wizards of the Coast figured out what someone with an elf and a human parent ...
Ask the player "why?"
First step to solving these types of issues is asking why they want a thing. If the character wants to be invisible all the time just for the sake of that, just say no. If they like the idea of being able to attack from being hidden or that type of thing then you can help them out.
The Gloomstalker Ranger is invisible in darkness to ...
This is answered directly by the box text at the beginning of every single Unearthed Arcana article:
This Is Playtest Content
The material here is presented for playtesting and to spark your imagination. These game mechanics are in draft form, usable in your campaign but not refined by

RAW, this isn't possible.
There are limited choices available for RAW races, and being an undead skeleton isn't one of them.
Given that you are just starting out as a DM, I highly recommend sticking with the vanilla rules as much as possible as you learn the system. This does mean asking your players to limit themselves as well to what they can build ...
This is likely unbalanced
For your tiefling paladin, this is likely at least a +3 to AC, which, depending on their build, could give them 21 AC at level 4 (shield + chain mail from Paladin starting gear, +3 base CHA modifier.) This is quite powerful relative to other options, and will improve with any additional ASI.
If this doesn't look that powerful to ...
First things first, your best bet is to pick a race that has the same build that you want your homebrew race to be like. If you want a Dextrous build; fast, light and agile, go with an Elf, for example. If you want a strong, resilient, brutish build, start with an Orc.
Try not to look at the race itself. As bad as it sounds, each race is just a collection ...
I've deliberately not covered aspects that are irrelevant to a mechanical evaluation.
Ability Score Increases: Charisma, Wisdom, and Constitution all increase by one.
Okay - Three static +1s is uncommon, but not unheard of (Triton is an example).
Age: Agias are created by magic and divine rituals, they do not age.
Excessive - No ...
Overall, Looks Good!
Almost all of these abilities have a precedent. Damage resistance is shared by dragonborn. Proficiency in what is essentially a two handed weapon does not currently exist RAW -Dwarves and Elves are only proficient in 1 handed weapons- but I don't think this is a big deal. Any class that isn't proficient in a two handed weapon ...
It's a little bit dangerous to experiment with custom rules as a beginning DM. The risk is that you hand out something that's too good, and then one of your characters is more powerful than the others and it creates tension.
(In particular, we have an existing antipattern where the DM invites their significant other to the table and then makes a bunch of ...
WotC didn't, so you shouldn't either.
There are currently no WOTC-produced player character races that are Large. I could speculate as to the reasons, but I have no designer-quote evidence to support it.
One answer to Are there any rules or guidelines for large character races? does bring up some good points, however.
What WotC did instead.
I will highlight specific problem points.
The ability score increase of four dexterity is too much, and the corresponding decrease does not balance it out. This is because normal character builds in DnD tend towards not using all ability scores equally, resulting in almost any trade that results in more primary at the expense of a "dump ...
Orc sub-races are not yet in 5e
As you noted, Volo's Guide to Monsters doesn't do this but a future supplement might. Given how orcs have become more humanized in recent editions, in terms of their background and culture getting a little more meat on them than "big humanoids with axes and fangs," it would make as much sense to make sub-races of orcs as it ...
This type of creature is not described in the rules
After sifting through all of the celestials and all of the fiends, it appears there is no mention of a pair that could procreate in such a way to create a part-celestial/part-fiend individual. You could, however, create such a creature using the Dungeon Master's Toolbox in the Dungeon Master's Guide where ...
He was a human from the Tabaxi tribe
The book makes this all very confusing, but Ras Nsi is indeed a Tabaxi. Except... he's not a cat person. In ancient Chult, the people of Chult lived in various tribes, and the largest of these tribes was the Tabaxi tribe.
It's a bit uncertain in-universe if the tribe was named after the cat-like humanoids, or if the ...
There are some descriptions in official lore, but nothing really showing the actual anatomy. There is, however, an article in Dragon Magazine #103, describing (But not showing) the anatomy.
Rules Cyclopedia (1991) gives the following description (and this description is repeated in several sources):
A centaur is a creature with the head, arms, and upper ...
I have never had a game where character creation was that prescriptive around the order things are done. The rules might say one thing, as Dale M points out, but just ask your DM and they are unlikely to enforce it.
The technical term is "Khoravar".
From the section on half-elves in the Wayfinder's Guide to Eberron (p. 77-78), under the heading "The Khoravar":
When two half-elves conceive, the child is always a half-elf. Over
the course of generations, families and communities of half-elves have
developed their own cultural identity. Members of these families
Wayfinder’s Guide to Eberron states that both high elves and wood elves are found among both the Aereni and the Valenar, so these groups are not subraces. Wayfinder’s Guide to Eberron does offer Aereni the option of a skill or tool proficiency with doubled proficiency bonus, and Valenar the option of alternate weapon proficiencies, but those modifications ...
Simply allowing more arms is overpowered
Allowing a PC to use a two-handed weapon with a shield is overpowered indeed. The game wasn't created with that in mind: either your character use a two-handed weapon to deal more damage or use a shield with a one-handed weapon, trading-off the higher damage for better protection.
By simply allowing a PC to have ...
On its own, the ooze type has (almost) no direct impact
There are virtually no race/class features or feats (or spells, or magic items) that apply specifically to oozes.
Only two spells, sunbeam and sunburst, do specify:
Undead and oozes have disadvantage on this saving throw.
The ooze creature type can also be chosen by a ranger as a Favored Enemy, ...
There are no hard rules associating a creature's size with their ability to sneak in this way. Mechanically, the Loxodon is as capable of learning the art of stealth as any race.
The fifth edition of DnD does allow for a way for GM to introduce "common sense" elements into difficulty: advantage and disadvantage. Having one's ankles chained together would be ...
Eberron Shifter is your best bet
The Wayfinder's Guide to Eberron has a new race, Shifters. Their "Similar and Diverse" description gives great flexibility to their appearance:
Shifters are similar to humans in height and build but are more naturally lithe and flexible. Their facial features have a bestial cast, with large eyes, flat noses, and pointed ...
This is an interesting question that could be rephrased as "What's not in 5th edition...yet?" because Wizards has indeed been filling in some of the gaps.
To start with, though, 4th Edition had much more source material... velocity(?) than 5th. (This is intended, as I understand it). Races are actually one of the easier things though!
At its start, 5th ...
Ask your DM
There isn't any official cross-over rock/forest gnome option, but it sounds like all you're doing is choosing Forest Gnome but building your personality similar to that of a Rock Gnome.
Ultimately, that's between you and your DM, but developing your own character's personality really shouldn't be a problem even if it's not your typical forest ...
I think this race is mostly balanced, but I have a few suggestions. Let's take each trait in turn from your stat block.
Ability Score Improvement: +2 Wis, +1 Con, +1 Str, -1 Dex
+2 to Wis and +1 to Con and Str would be balanced without needing the -1 Dex to counter-balance it, if we compare with Half-Elves (PHB, p. 39), who get +2 to Cha and +1 to two ...
This truncated table shows the ranges for the races in the Basic Rules
I didn't include the remainder of the races in the Player's Handbook because the table used to calculate those tables is not available in the SRD and therefore cannot be published due to copyright.
This table uses the Random Height and Weight table found in a number of rulebooks and ...
