Bellona

Hey everyone. This is the guide for Bellona, Darmoor’s apostle who only feels alive at the edge of death. Here you’ll find the boss details, the Insane gauge, all of her attacks on Easy, Normal and Hard, the mark collection and the rewards, so you can decide if she’s really worth it.

Values use the format EasyNormalHard: the first number is for Easy, the second for Normal and the third for Hard.
01

Boss overview

Bellona is a fight with almost no map mechanics: it’s you against her. Her red attacks take a life instantly, so every hit counts.

Death Count and the Insane gauge

These are the two mechanics you need to understand before fighting her. The Insane gauge decides when Bellona gets aggressive, and the Death Count decides how many mistakes you can afford.

Insane mode

  • When the gauge reaches 1000, Bellona enters Insane. If she is in the middle of an attack, she enters once it ends.
  • The screen goes dark and Bellona only appears right before she attacks.
  • She only uses red attacks, and all of her cooldowns reset when Insane starts.
  • She takes 30% more final damage, so it’s the best moment for your burst.
  • Every attack she uses costs her some of her own HP. That segment shows up on her HP bar in a different color.
  • If she hits you, she recovers part of that HP: 1% per hit (2 players: 0.5%, 3 players: 0.33%). When Insane ends, the remaining damage is locked in.

Leaving Insane and recovering a life

  • Insane ends when the gauge goes back to 0. If she is in the middle of an attack, it ends once she finishes.
  • If you get through the whole Insane without taking a single hit (mark collection included), you recover 1 life. This is individual: each player recovers it on their own.

Tips for managing the gauge

  • When you bind Bellona outside the frenzy, she switches to the next state right away: from normal to Insane, or from Insane to normal. Use it to line up Insane with your burst.
  • During Insane, every hit you take gives Bellona HP back. Dodging well is also dealing damage.
  • In a run close to the minimum damage, keeping Bellona in Insane as long as possible adds up a lot, because her self-damage stacks.

Phases

The fight has two phases, and in the second one Bellona attacks much faster. Some attacks change their warnings or don’t show them at all.

  • Bellona attacks as she appears at the start of each phase. Her entrance animation also deals damage.
  • In phase 1, players spawn on the right and she attacks the left side of the screen.
  • In phase 2 she hits 3 times, so if you stay close you can lose up to 2 lives. Binding her during the entrance cancels it.
How to dodge it: Get away from where Bellona lands as soon as each phase starts.

Tips for purple attacks

  • Fight on top of Bellona. That way the swing doesn’t hit you and you stop her from teleporting.
  • Purple attacks don’t take lives, but they do lower the gauge. Avoid them so Insane comes when you want it.

Red attacks

She uses these both inside and outside Insane. Each hit lowers the gauge by 200400600 and takes 1 life. Their cooldowns reset when Insane starts, and on Hard, during Insane, they appear up to 0.12 s later.

  • If she can create a mark during Insane, she creates the Sword mark.

How to dodge it: The first hit comes from the center, so get out of there fast. Then follow the path with your eyes and move where it won’t go. The final ground slam is dodged by jumping (65 px). This is the attack most players struggle with, so practice it.

Tips for red attacks

  • Learn to read the somersault posture: upright, crouch; upside down, jump.
  • For the phase 2 tracking attack, memorize the order of the 3 warnings before she starts attacking.
  • During Merciless Charge, don’t stay against the edges of the map.
  • If the pinball gives you trouble, practice it before anything else. It’s where most lives are lost.
