Harmony - Troop Symmetry

Regarding racial features: - We have the characteristic Necropolis ability, "Undead." - We have the characteristic Inferno ability, "Demon." - We have the characteristic Orc ability, "Raging Blood." Currently, the following changes have been made: - "Demon" is now a racial ability for the Dark Elves (grants immunity to Unholy spells and vulnerability to Holy spells). Renaming options for Dark Elves: first option, make it consistent with the lore as "Malassa's Apprentice" (ability for all Dark Elf units from Heroes 6); second option, "Mark of Darkness," "Shadow-branded," etc., as calling all units from 1 to 7 "apprentices" seems somewhat awkward (in my opinion). - "Raging Blood" will now be "Blood of Demons" and will be possessed by two races: Demons and Orcs. Should other races be given a racial ability? For the Dwarves, it would be natural to have a connection to defense, for example, "Rune Power," "Arcata Warrior," etc. Mechanically, this could be implemented as an inability to reduce the defense of Dwarf units (an ability called "Armor"). For the Elves, something related to agility could be given, for example, the ability "Etherealness" could be renamed to "Elven Agility" and the chance of it triggering could be reduced to 25% (meaning that an agile unit has a chance to dodge a physical attack from the enemy). Since the Magic army is a collection of constructs and elementals, they don't really need a special ability (the abilities "Construct" and "Elemental" already serve this purpose). Finally, there are the Humans - since Humans are canonically balanced and unremarkable warriors, they don't really need a special characteristic.
