Tale of the Last Promise is a dungeon-crawling RPG, which means that the game’s battles take place from a first-person perspective, too, similar to Etrian Odyssey or Wizardry. Since you can’t see your own characters on the screen during battles, enemies get all the love, and the interface looks very neat.
The system being described in the video above is “control of hate.” In Tale of the Last Promise, certain attacks draw the enemy’s attention. For example, Kain’s attack does a fair bit of damage to the knight in the video, which makes the knight turn on him.
The opponent in the video is powerful enough to knock a member of your party out in two hits, which means you need to get him to keep shifting his attention between different party members. To draw his attention away from Kain, Wolf uses Defense Line in the following turn. This allows Sara to heal Kain while the enemy isn’t paying attention to him.
Imageepoch look like they’re trying to keep the first-person battles feeling lively, too, with a bit of dialogue between characters.
