@Dandoclase you need to choose your words wisely before calling someone “scum” in the forum. Based on your posts, you do not understand the game. I will attempt to help you understand below.
The first image you posted is an edited item by GINZO. The Stolen Galea gear does not have Armor affix.
Eternal Divination with Cyan\Obsidian All Resist affix is possible. The epic affix “All Resist” can become obsidian affix. All eternal gears with affixes in the obsidian affix pool (below) has a chance to become cyan\crystal affix.
The last one you posted is also possible. The Stolen Galea gear has epic HP% Which can become obsidian affix. You cannot see in the legendex image there is an HP% epic affix…
If a gear has an epic or legend affix that is in the obsidian affix pool (below), there is a probability that gear can drop with the obsidian affix. I provided examples of this yesterday to other players.
