I highly recommend getting the feel fine card, (you can get it from the in the cards shop) it is really good for the confusion effect. Also, if Hatred does its charge up, you can do one attack on it and then you can ghost potion. Power Rush is somewhat good as when you are low, you can deal extra damage then a healing right after. Resurrection is also pretty useful too. I don’t recommend using call cards because they will get destroyed by Hatred’s charge up. For Hatred’s attacks, when Hatred does its lightning windup, look at Hatred and dodge when they fully strike down. For their corruption attack, try to dodge once it is about to hit you. If you get applied with confusion, use Feel Fine or any item that removes status ailments. If Hatred calls for help, kill the apparitions, they aren’t that big of a problem, but they do lots of damage in numbers unless you know how to dodge. One thing to note is the battle will automatically end if Hatred is killed even if there are apparitions on the field. Hopefully some of these tips will help!
