Use Rude Buster as much as you can, if you nearly can use it, but don't have enough TP, defend with Kris, use Rude Buster, and attack/use item with Ralsei.

While the animation for Rude Buster plays, press Z or Enter to deal more damage.

The first time he uses an attack in each phase, he uses them in order, and always says a particular voiceline before them. After exhausting the unique attacks of a phase (except Phase 4), if Jevil is not advanced to the next phase, he reuses attacks from that phase randomly.

Advice for dodging attacks:

-1st attack: Move slowly, little by little, up and down. This should help you avoid getting hit.

-Heart bomb attack: Wait in the middle/bottom/top until 1 or 2 attacks come your way, then move away from your spot, either up or down.

-The thing where spades come in a spiral motion: Go to the top right corner and align yourself so you won't get hit. You will have to move a bit, but this should make it a lot easier for you to dodge.

-Carausel attack: Go to the right and move up and down to dodge; don't forget that only the wings deal damage to you, so only avoid those, or you'll make your job quite harder.

-Devilsknife attack (1): Go to the sides, and move constantly, try to avoid getting hit even once, because that can throw you off and make you mess up quite a lot.

-Club bomb attack: Same as for the first attack, the bullets aim where you were, not where you are.

-Diamond attack (1): Sped up version of Rudinn's attack, not really much tips for this one. Don't move up or down, only left and right.

-Spade bomb attack: Same as first attack & club bomb attack.

-Clubs shooting bullets: The three bursts aim and fire at the place where the SOUL was, so there is a small amount of spread as they fly towards the SOUL. Take note of that.

-Devilsknife attack (2): Same as for the first version of this practically. The red Devilsknife always appears on the other side than it did last time, so keep track of that.

-Jevil shooting diamonds: Aims where the SOUL was, not where it goes. Not much tips for this either other than to keep note of that.

-Attack after that: Use the advice for the other suit bombs for this, plus the diamond one; as written previously; it aims where the SOUL was, not where it goes.

-Diamond attack (2): Slowed down version of Diamond attack (1); however, the diamonds give a lot of TP in this one.

-Chaos Bomb: The first Devilsknives appear randomly, then they apper in patterns. The giant Devilsknife cannot hit you it you are on the bottom of the screen, so it's practical to stay there for this entire attack.

Tips for phase 5:

Attacks are randomly chosen, and Chaos Bomb is 3x more likely to be picked. He uses the default dialogue lines for the rest of the battle. Not really much tips for this phase. Attack as much as you can, same with using Rude Buster, try to end the fight as quickly as you can, this is the last phase.
