More potions in ancient city

We need to change loot in ancient city. Besides the regeneration potion, ancient city must have another one. In chests of ancient cities should also spawn healing potions. It might also be worth adding the potions on night vision, but only at level 1, so that the passage of the dungeon does not seem like such an easy task. A reward in the form of more potions would add even more meaning to going to this dungeon.
