I can't know if you can have all of them...
I do and you cant ...
There is enough material to create only two items of your choice.
what I can say though is that you might be able to apply the adamantine material to anything if you are better than me at understanding how the item visuals are defined (the bar is low I would say ^.^') and apply it to a copy of the base metal gloves and boots.
Well ... if you are talking about moding, that is not my jam either.

I was talking about the uggly habit Larian have with giving us only some parts of sets ... and im talking here purely visual side of things, i dont really care about stats.
So far we can get:
- Githyanki armor ... but not gloves, boots or circlet ...
- Druid armor (boots i gues, kinda) and some kind of Druidic head gears ... but not gloves
- Mail gloves and Boots, but no fitting chestpiece (if you find any, please show me ... ringmail is not fiting tho :P )
etc. etc.
There is many and i dont wish to list them all. :P
Theese "if you heal, target gets" are perfect for supporting Clerics ... and if you combine them right, you also gets some benefits ...
thanks for the tip, I was so foccussed on my own op modded gear, I missed half of those
You welcome.

So far its my favourite Cleric gear ... usualy i combine that with either that Mace from Minthara, or Vision of the Absolute ... since both can give my meele targets debuff causing advantage when attacked honestly, OP as hells.

I absolutely agree and my mage with its 50 AC and +39 to hit also thinks that those +x bonuses are nice and all but it just lacks fun and diversity. on the other hand, some bonuses help, so... it's always a matter of balance
Something tells me your wizard is a little higher level.

But anyway, agree ... both options is welcomed!
but I guess it would still be more useful on some character than others.
This was exactly my point.

If you play Barbarian you will hope for different bonuses than if you play Wizard.

I like this necklace, it is one of those always useful items you were asking for. I guess I am not the best at balancing things ^.^
Well ... its usefull for caster who have Magic Missiles, yes ...
Its strong artefact, no doubt about it ... almost ridiculously strong ...
But again, if you give that to Lae'zel who is battlemaster, you only get one cast per long rest ... quite strong cast, and guaratnted hit cast ... but still just one, unable to crit, and honestly in many cases weaker than your other abilities ...
And switching it in battle costs Action.

Phalar Aluve gets an Excalibur level introduction, and then it's just a vanilla +1 like the stuff you already bought from Dammon.
It was worst in previous patches, it might get better and / or get a specific model, I'm not that worried, just curious
Personaly i really hope for some blood based Sorrow-like magical effect. :3
I know you didn't asked me but I'll still tell you that 300 is mighty cheap for the adamantine property since uncommon items in d&d are priced at 500 gold pieces (50 000 copper coins if you are trying to sell food and tableware to get those)
I believe you have that other way around ...
Its not like Regular Steel helmet have property of Adamantine one ... its tht Adamantine helmet have property of regular helmet + its own for material used.
