The trick is that they never got that trait working so they mentioned it in the pinned bug thread for that source.

Don't worry, you aren't the first person to make a thread without checking other threads first or even the first dozen or so.

This still doesn't appear to be fixed. Any word on an update for it? I'm soon running an Eberron campaign for new players and would like to make the process as easy as possible for them.

 I haven't heard an update. It really is taking too long.

Nuff said.  The arcane lock, armor of agathys etc.. are not showing up in my character sheet for the Mark of warding Dwarf.

Some advice? Check pinned threads. They usually have info.

Literally first post in that thread. I'll even put it in red and bold, even make parts bigger.

RACES

• Goblinoids - This is Bugbear, Goblin, and Hobgoblin. These races are presented as functionally identical to their publication in Volo's Guide to Monsters and thus the standard descriptions from that sourcebook remain in place. Eberron: Rising from the Last War Chapter 1 gives background lore for on these races for the Eberron campaign world.
• Dragonmark variants/subraces - there are 13 of these presented in Chapter 1. All of them have a racial feature named, "Spells of the Mark" that adds spells to the character's spell list, if that class has spellcasting or pact magic. We haven't been able to model that correctly at this time, but will implement as soon as we are able to.

This is being worked on and they have started rolling out backend changes that will enable them to soon add this.

Ah, yes, very sorry.  I did look at names of threads but it wasn't obvious.  I'll try to do better :-)

Hello Laserwhit! This feature is not yet available, but the team is working on the development needed to support this unique feature. 

We'd always rather have too many reports of an issue, than too few, so thank you for your report. :)

This feature has been missing for quite a while now. It didn't take this long for the guild backgrounds to get a similar feature, any feedback in regards to that? I know class variant UA came out at around the same time, is that related?

I am currently playing a Mark of Shadow Elf named Dorian. He a Lvl 5 Gloom Stalker Ranger, and Lvl 3 Assasin Rogue. On both the mobile and web versions of my character sheet, the spells I am supposed to get from the Spells of the Mark feature of my race, do not appear on my spell list. The exception to this is Disguise Self, which is also a Gloom stalker spell and shows up as such. Anyone know if there is a workaround or if I just have to add the spells manually?

This is known - and something covered in the pinned Eberron: Rising from the Last War - Bugs and Support thread.

You'll likely find a workaround in that thread too.

Oh ok, thank you, I wasn't aware that this was a known issue.

Still no fix :(

Eberron Dragon Mark races gain the Spells of the Mark trait which reads, "If you have the Spellcasting or the Pact Magic class feature, the spells on the Mark of Healing Spells table are added to the spell list of your spellcasting class." I have a Mark of Healing Halfling Wizard at 1st Level and the two 1st level spells cure wounds and healing word are not available to add to the character's known spell list from the character sheet page.

This isn't a bug, the feature just hasn't been implemented yet. If you go to the Eberron thread in this channel, you'll see this is mentioned in the first post

I tried searching the forums for "Spells of the Mark" and "Eberron" but both came up with empty results for some reason. I was able to find the Eberron thread you mentioned though. Thanks for directing me to the thread!

I am trying to create a multiclass Rogue/Warlock, 4 levels in rogue (Arcane Trickster), and 3 levels in Warlock (Hexblade). My race is Mark of Shadow Elf, however, the mark of shadow spells aren't showing up in my spell lists. I have level 2 pact magic from warlock, but I do not see pass without the trace spell from the Mark of Shadow Racial Spell Table. Help?

Spells of the Mark have not yet been implemented yet

Well that would explain a lot. Thanks

The search function is bugged ATM (and not that good when it isn't). There is a pinned thread on the front page for ERftLW and this is mentioned in the OP.

I made a rogue Mark of Shadow Elf with the first few levels and added warlock. But the spells from Mark of Shadow Elf dont show up on the known spells.
I have try to make a warlock only, but the spells dont show up there ether.
