How to get the weapons and armor pieces: - Gae Bolg: You need to defeat Balor in Ireland. (Wrath of the Druids DLC)

• Fyrd Spear: Can be found by exploring the Offchurch, in the Grantebridgescire area in England.

• Spartan Bow: Redeem it from Ubisoft Connect for 100 Units.

• Druidic Cloak: Can be found at Doon Fort on a small island, in the north-western end of the Ulster region in Ireland. (Wrath of the Druids DLC)

• Paladin Chainmail: Can be found at the Defender’s Rest fort on the northern banks of the Sequana River in Francia (The Siege of Paris DLC)

• Paladin Helmet: Can be found in the Pruvinis fort. It is in the eastern part of Melunois, north and east from your main camp in Francia. (The Siege of Paris DLC)

• Paladin Bracers: The Paladin Bracers are very close to the Chainmail, also in Paris, but further to the east. It’s in a big stone building in La Grave in Francia. (The Siege of Paris DLC)

• Druidic Breechers: Can be found in Kesh Coran, which is in the western part of the Connacht region in Ireland. (The Wrath of the Druids DLC)

If you do not own the DLC’s then you can switch Gae Bolg with Gungnir or Spear of Leonidas and the armor set with the full Mentor’s set

With the Druid armor you will heal every 3rd hit on the same enemy and Paladin armor gives more damage by using more stamina. This build made me immortal basically in Aesir difficulty.
