Foul Play

The latest Dota Underlords update added inventions to the game and made creatures of the 5th rank the leaders of their alliances. If your leader gathered his alliance (at least the first level), he gets the effect of the leader.

For example, the Disruptor became the leader of the Warlock Alliance, and its effect - a connection from the Warlock Alliance is formed with two allies instead of one. In addition, the collected alliance by 15% increases the chance that the hero leader in the shop will belong to your alliance.

Inventions can be placed on the battlefield. They will act like ordinary creatures, but are not taken into account when counting creatures. They can be moved, they have health and armor. So far, Valve offers 4 inventions of 2-4 categories. They can block, provoke, heal and call on zombies.
