Using Curses

Sam and the team moved to the city where Leader 3 is currently located.

Both leaders are in the same realm at the moment but in extremely different situations. Leader 1 lost almost all of his troops except for some close confidants.

The rest of them all died. Now all that is left is a direct clash between him and Leader 3 which could subvert the situation.

While Leader 3's group is tracking, Leader 1 is escaping and hiding while killing Leader 3's troops here and there. He threw all the rules of war out of the window. Since all his territory is occupied by Leader 2 and Leader 1, there is nothing much they could do to him in return. 

But he is sure that once he was spotted, the game would reach the final stage and he wanted to deal as much damage as possible.

The team got this information and decided to help Leader 3 a bit by tracking the other party. So, first, they placed surveillance at Leader 3's place and then waited for his move.
