Travian Hero's Mansion Building Costs

Hero's Mansion

Hero's mansion is needed when you need to occupy an oasis. At level 10, it will allow you to occupy 1 oasis, 2 oases at level 15, and at its maximum level (level 20) you can occupy 3.
Sending the Hero to other villages

The hero is often moved to another village with a view of conquering an oasis from that village. The attacking village must be the hero's mother village, otherwise, he will not be able to be included in the attack. a hero is moved to another village by sending it to aid there and also ticking the box "Move the hero".
Occupying oases

A village can occupy an oasis if it attacks the oasis with a force great enough to subdue all the animals that are present. The attack must also include a hero, who must survive the attack. The oasis will only be captured if there is a level 10, 15, or 20 hero's mansion built in the attacking village, and can still conquer an oasis (1 on level 10, 2 on level 15 and 3 on level 20). When the oasis is captured, it will be seen in the report, as well as in the 25% increase of corresponding resources in the village.
