warm ups in mobs of death are rewards for beating waves, for exampleyou will be given an specified ammount of gold and health, or heck! an whole ahh group of soldiers for just beating a mob of minecraft mobs!! but the only thing is that, when your almost at the final wave, there are no more warmups so you have to prepare. also did i mention that i tried to make the game easier with a few stuff that i will talk about later
