Hero on ruin add undead lore points for usual battles

[Solo]

Is this right that a hero receive additional strength points from undead lore when he stays on a ruin?
I see this in my game AmIEvil. A ranger attacks a dwarf in ruin and she has own strength 45 + leadership 6 + undead lore 16 and result strength is 67.

This is true, heroes fighting on ruin terrain add to their strength all UL they have.

Regular units (scouts/wizards/ghosts) add their UL to their own strength too.

Thank you, my friends.

But only on land ruins, not shipwrecks!
