Heroes 6 - Discussion

Ment, you're copy-pasting again without reading.

Once per battle, one friendly core or elite stack can be enhanced. Bonus creatures disappear after the battle.

How should I understand this? I enhance a unit (associations with a stone face or shield, and after the battle, the bonus creatures disappear. Nonsense.) If you translate the original, it turns out that the unit will be reinforced. I don't know how it works in the game, but please correct it to make it clear.
