Great upgrade for 17th level casters (and 20th level clerics) to get a free permanent, scaled to 8th level, flying mount.

Now, why fullcasters needed a better Find Steed for Wish is a bit of a mystery, given this is supposed to be the Paladin's steed... so it is very peculiar that the best "Find Steed" will always be a Wizard's Find Steed (or any fullcaster taking a 5-level dip into Paladin). It seems a bit short sighted and a fairly disappointing choice by the 2024 PHB design team.

Now, if the goal was to give the 2024 PHB Paladins their iconic magical steed from the heavens (or whatever), a good first step would have been to make Find Steed / Find Greater Steed a non-Wish target by making it feature (say, by tying it to the Paladin's Channel Divinity) non-spell.

Hell, it certainly should not scale past 5th level, because, Paladins don't get a spell slot above 5th level. Instead, the team made Find Steed (2024) scale entirely off spell level, so anyone committing to Paladin will never have the best version of their own iconic feature. Now, Divine Smite has a similar issue after the removal of its previous spell level cap and being turned into a 1st level spell, it just scales faster and much better multiclassing, prompting the 2024 PHB Paladin (who doesn't even have exclusive access to smite spells like Wrathful or Searing) to never be the best at what is supposed to be their spells. At least it isn't a Wish target.

The Paladin class feels like a prestige 6 level dip for a charisma based full-caster, with its main stick from 2014 being disseminated to the Warlock, Moon Druid, and Zealot Barbarian, before being turned into a BA spell variant of Brutal Critical for the 2024 PHB Paladin, oh well.

 Nothing you wrote here is different from the way paladins have always been since the 2014 rules.  There was never a single thing a paladin did that wasn't done better by Paladin 6 / Bard X or Paladin 6 / Sorcerer X, including the 2014 version of Divine Smite because a multiclassed full caster would just have more spell slots than any paladin at the same level.  

How do DMs rule this spell working in Sigil? Any changes or flavor of steed summoned?

Compared to 2014, I think this is more streamlined as you are given a stat block that has scaling through upcasting.

In regards to the unclear rules regarding to mounting, and controlling the Steed's (and any mount) Action and Bonus Actions, I would rule that it takes an action to mount the steed and you can control it within you turn. Its Action and Bonus Actions are separate from yours.

This gives you the ability to fully use your movement and Bonus Action allowing a Paladin to cast a spell before striding into battle.

Alternatively, a DM could rule that it takes 15-feet of movement to mount allowing you to use your Action while on the mount.

The character would have to be off the mount. The spell explicitly states the mount is controlled while ridden.

(Edit) These are bonus actions & mounted combat makes no statement about those.

Can the Celestial steed heal itself? I would assume so, as many spells and abilities that have the range of Touch can target the caster.  This is similiar logic.  That would make the steed significantly more durable in combat.

It would have been nice to give it a couple of saving throws (like Dex and maybe Con) and skills (like perception and athletics) and attack damage that would benefit from your proficiency bonus, like the Artificer's summons (look at Steel Defender, for example).
Also, change the to HP to (10+ proficiency bonus) per spell level. So the hp would be:
LVL 2 (Paladin level 5, PB +3): 26 HP
LVL 3 (Paladin level 9, PB +4): 42 HP
LVL 4: (Paladin level 13, PB +5): 60 HP
LVL 5: (Paladin level 17, PB+6): 80 HP
The steed then stays at around half as much HP as the Paladin through all the Paladin's levels, as opposed to dropping off sharply to around 1/3rd of the Paladin's HP at the higher levels.

The reason its saving throws are poor is because it's designed with a paladins aura of protection in mind. 

Hello quick question from a newbie.
So lets say I am a paladin summoning the stead with the lvl 5 faitful stead trait. Does that count as the speel beeing cast at lvl 2, so the hp equals 25?
Second question. If my Paladin is mounted on the celestial stead, and the stead uses Healing Touch and my paladin regains hp, does that also activate Life Bond so the stead regains hp at the same time?

1. Yes. If you're casting it without a spell slot (which that Faithful Steed feature lets you do once per day) then the spell is cast at its minimum level, which for this spell is level 2. This means the steed has 25 HP (5 + (10 * 2)).

2. No, because Life Bond only applies when the Paladin regains HP from a spell, and the steed's Healing Touch ability is not a spell.

Yes, it can. This actually doesn't have a range of Touch (despite the name) but rather 5 feet. But it doesn't matter, because any creature is always within 5 feet of itself.

If it were intended to not be able to heal itself, it would say something like "one creature other than the steed within 5 feet".

Thank you

The reason that nothing except d20 Tests, Feats, and Species Traits use your Proficiency Bonus in D&D2024 is because your PB is tied to your total character level, not your class level. So with your change you could literally just go Paladin 3/Barbarian 17 and still improve your mount's HP.

It makes sense for d20 Tests, Feats, and Species Traits because you get better at those through just general adventuring - but the intent with most other features (such as spells) is that you have to improve them intentionally, such as by upcasting, or increasing the relevant ability modifier.

Does the Fey Step not need LOS now?

This stat block is not able to added to the Extras page, and/or doesn't show up after cast like the other animals do. I've currently modified a warhorse with a bunch of customizations. Could we get this added as an option in the character section for adding companions?

You generally want to use the D&D Beyond Feedback forum on the main forums if you want anyone with the power to make changes to see it. That said, one thing they've said several times is that there is currently no way to add stat blocks to the Extras page that have stats that change dynamically with the spell slot level used to create them, which this one has a bunch of.

Good tip on the feedback forum, didn’t know that existed. 

kind of figured it would be a dynamic thing and might not work. They do have the ability to adjust for and/or note differences based on a spell level casting; more damage, etc. Figured there might be some way to do this for the summoning too?

Can someone please explain how I add Find Steed to my character sheet? 

And thank you

In the character builder, go to the "Class" tab, and you'll find a "Spells" section. That's where you select which spells your character has prepared.

If that's not working for you, please give us some more specifics about what the problem is.

Is there a way to add this into the 'extras' section of the character sheet without picking e.g. warhorse and modifying it?
