Heroic

In Heroic Mode u have 5 lifes and when they run out u can buy a life for 29 R$ or go back to the lobby. Also the NPCs and bosses are a bit harder to take care of and u have lower chances of clearing the dungeon on this mode. You can select it while u are looking into the dungeons from the left window that says "Difficultiy" You choose Normal Difficulty then select the dungeon you want to raid and then wait for a party or just go solo and u are done
