Well, I see it. In that case, that would apply to machinery that doesn't have the mechanical ability (and I can't even think of one!), or plants that doesn't have the Plant ability (and I can't think of one again!).

It would appear that the description is very misleading.

Here's the translation of those 2 abilities:

Plant:
Thorn Hunter, Thorn Warrior, Royal Thorn, Ent, Royal Ent
All plants have 100% vulnerability to Fire
50% poison resistance
Resistance to the following spells: Healing, Resurrection, Plague, Weakness, Necro Call
Resistance to the following abilities: Healing, Resurrection, Prayer, Necro Call
Resistance to the following debuffs: Bleeding, Shocking, rage (it cannot go out of control when bitten by a wolf, werewolf, etc.)

Mechanical:
Droid Guard, Droid Mechanic
Always neutral morale
Immulity to Poison (80%)
Vulnerability to magic (-50%)
Cannot be healed or resurrected

EDIT: BTW, sorry about my previous posts. The russian version didn't have that idiotic discrepancy, so I expected everything to be normal here as well. I guess I was sorely mistaken.

Prayer description in the Russian version:

Heals and resurrects units around the paladin, recovering 24 points (24 for each paladin in the stack) of health. Affects only level 1-4 creatures. Undead and Demons next to the paladin receive 14-16 magic damage and run away in fear. Does NOT resurrect dead stacks, plants and mechanic units.
