Here is the links to the armor part of your question. As for the pieces of armor need to get hero armor. They come from different areas in, NF and EotN.
NF has Stolen Sunspear Armor that comes from Dajkah Inlet Challenge Mission. It does not drop, but instead appears in players' inventories at random as a reward after killing a Corsair Guild Lord.
The chance is per individual player, so killing a single Guild Lord may result in more than one player receiving the item.
Heros that can take use this upgrade. To apply the armor you need to visit the NPC Bahldasareh in Dajkah Inlet.
* Koss
* Dunkoro
* Melonni
* Acolyte Jin
* Acolyte Sousuke
That mission I've done with Heros and Hench just like fighting countless Corsairs thru the storyline of Nightfall.
Ancient Armor Remnants can only be obtained in the Remains of Sahlahja Challenge Mission. It does not drop, but instead appears in players' inventories at random as a reward after killing a Lost Soul or Maddened Spirit.
You will not receive Ancient Armor Remnants for every Lost Soul or Maddened Spirit you kill. They are randomly given to the player.
Heros that can be upgraded with Ancient. To apply the armor, you need to visit the NPC Johe in Remains of Sahlahja.
* Tahlkora
* Zhed Shadowhoof
* Margrid the Sly
* Master of Whispers
* Razah
This one is a bit of pain because it is a solo challenge mission.
Primeval Armor Remnants can be obtained in the Domain of Anguish and during The Ebony Citadel of Mallyx mission. This item does not drop, but instead appears in players' inventories at random whenever a Domain of Anguish chest is opened or one of the Lords of Anguish is defeated. Furthermore, when Mallyx the Unyielding is defeated a chest spawns which contains one Primeval Armor Remnant for each party member. One Primeval Armor Remnant can also be obtained randomly from a Coffer of Whispers.
Heros: Koss, Dunkoro, Melonni, Acolyte Jin, Acolyte Sousuke, Tahlkora, Zhed Shadowhoof, Margrid the Sly, Master of Whispers, Norgu, Goren, General Morgahn, Zenmai, Olias, and Razah. To apply the armor you need to visit the NPC Armorsmith of Whispers in Gate of Anguish.
These might be one of the hardest ones to get thru the normal ways because its hard to find a good pug for this elite mission. But thank god that ursan is gone because it was making the worst of players able to finish it.
Now for EotN:
One Deldrimor Armor Remnant can be acquired from the Hierophant's Chest, which spawns upon defeating Duncan the Black as part of the quest The Last Hierophant.
Heros:
* Vekk
* Ogden Stonehealer
* Jora
* Pyre Fierceshot
* Kahmu
* Gwen
* Xandra
* Livia
* Hayda
* Anton
To apply a Deldrimor Armor Remnant, you need to visit the NPC Gunnar Poundfist in Gunnar's Hold.
Cloths of the Brotherhood drop only from the Chests of the Brotherhood spawned after winning the Glint's Challenge mission. It's a guaranteed drop from the chest.
Heros: All GW:EN heroes may have their armor upgraded.
Talk to Master Armorer Kor in the Central Transfer Chamber to apply a Cloth to a hero's entire armor.
Hope this helps Nos.
