Eternal Artefact is an Item in Divinity Orginal Sin 2.
It's hard to say whether this is magical or mechanical. Or both. You can probably put this thing to good use somehow...
Location/Where to find
- Act 2 - One can be found in a container inside the Ancient Temple in Blackpits Cave
- Act 3 - Several can be found around the island inside the black containers.
- Act 3 - One can be found, hidden, in the southeast corner of the "water temple". It's burried and needs to be dug up.
- One in a chest in underground Temple with Automatons guarding the Eternal Stormblade
- One at a hidden dig site near the Place of Longing
- One in a chest next to the portal to the Academy Proving Ground
- One on an Eternal Sentinel inside the Academy Proving Ground
- One in the library of the Academy
- One in the left side table (facing the Wells) inside the Arena of The One
- One more I can't remember but outside on Nameless Isle for sure...
- Act 4 - Several are in the doctor's prison. Another can be found in Lord Kemm's vault in a dsiplay case.
There are two types of artefacts (same name, different icons)
Combined with armor gives (tested on lvl 18 armor):
Works with some unique items
- Chest: 10% air res
- Belt: 2 Strength, 1 warfare
- Gloves: 2 constitution, 10% earth res
- Leggings: 1 polymorph, 10% air res
- Boots: 1 thievery, 0.1 move points
- Neck: 10% Fire Resist, +2% Crit, +5% Dodge
- Ring: 10% Poison Resist, +1 Scoundrel
Combined with weapon
- (Dagger, Bow, Axe, Mace, Spear, Sword): +25% (of weapon damage) as bonus Air damage, +15% chance to set shocked for 1 turn
- Works with some unique items
- Adding poison or shock damage to a weapon overwrites the other damage, but not the on-hit proc effect. IE: Adding poison damage using (for example) an ooze barrel and then adding shock damage with an Eternal Artefact will make a weapon with 10% chance to set poisoned and 15% chance to set shocked, but it would only have bonus shock damage.
- The bonus shock damage from an Eternal Artefact is notably higher than the bonus poison damage when enchanting weapons.
- Example: Level 20 Falone Scythe: 16-19 poison vs 31-37 Shock. Ignoring resistances, one's Geomancer skilll would have to be much higher than one's Aeromancer skill to overcome this difference (~20 Geo to 0 Aero, for example), such that it is essentially always better to have the shock damage. Shock is also generally less resisted than poison, thanks to undead creatures.
There is also one item called "Ancient Artefact." If right-clicked on, it does not have "combine with," meaning there is no recipe associated with it. It is also only worth 4 gold. There is no known quest associated with it. It is Vendor Junk, seemingly.
