Mending

In the SPECIAL column in the Cleric spell list it does not show "M".

Then when I go into the spell itself it shows "M".

This is true of a number of spells in the special column in spell lists.

Is the special column in the spell list of any use if I have to go into each spell to find out the requirements?

Can no longer be used to repair constructs. Only difference.
So basically, where this was incredibly useful for an Artificer with a Defender before, now it is incredibly less so.

I've heard before you can use Mending on a corpse to reconnect severed limbs (or even a head), since a corpse is an object and a severed limb could be considered a break or tear in it. Then after Mending the corpse, you can use Revivify or Raise Dead to restore a PC with all restored limbs since Regeneration spells doesn't come into play till 15th level. Is this legit?

According to the 2024 PHB, within the rules glossary:

"An object is a nonliving, distinct thing. Composite things, like buildings, comprise more than one object."

Well, a corpse is distinctly a corpse, which are famously known for being not alive. I'd say it's more clear cut than ever in this edition. Also, if you want to use Revivify on a fresh corpse you plan to mend, you must first cast Gentle Repose! By the time you've finished casting Mending (which takes 1 minute), the time frame for Revivify to work will have already passed.

So you're saying this isn't in the new artificer list?

I don't think that's true. It doesn't say it can't be used to repair constructs, and the description of the Steel Defender feature still explicitly says that if this spell is cast on it, it regains 2d6 HP. That still applies.

Also worth noting that with the 2024 update, all of the normal healing spells can now be used to heal constructs as well.

 In Eberron Forge of the Artificer they don’t state that casting mend on the steel defender heals it anymore.

I like this spell, good

Kinda curious what the collective wisdom says....

Party I was DMing interrupted a magmin in the process of burning up the personal letters and journal of a recently deceased wizard. I had created the notes so that about 1/3 of each of the messages, more or less, was burned away, leaving them to connect some dots. Enter the bard with MENDING. 

No doubt that mending would mend the parchments themselves. But would it restore the writing on the parchments? In this case, I allowed it to, because I default to things turning out in the players' favor when they make good use of abilities and resources, but I'm curious what other players and DMs think.
