A complete strategy for damaging the Sun, hitting weak points, and topping the damage leaderboard for Star rewards.

Overview

The Sun is the central PvE boss with over a million HP. Beating it isn't about soloing - it's about dealing the most damage to claim the largest share of Star rewards.

Because the reward pool is split by damage contribution, your real goal is climbing the damage leaderboard. Every extra percent of damage you contribute translates directly into more Stars at the end of the fight.

Sun HP:1,000,000+
Goal:Top the damage leaderboard
Reward:Stars

Sun Damage Strategy

A repeatable routine for maximizing your Sun damage across every attack window during a fight, no matter how strong your current holes are.

Each step increases your share of the reward pool, and timing matters more than raw hole power in most fights.

Launch when your strongest holes are ready and protected, and chain your attacks around the cooldown for steady contribution throughout the event.

1

Build Strong Holes

Reach late tiers for enough base damage to compete for the top reward shares.

2

Launch at the Sun

Send your strongest holes at the Sun the moment an attack window opens so you don't lose uptime.

3

Hit Weak Points

Aim for weak points the moment they spawn, since they deal heavy bonus damage and decide your leaderboard rank.

4

Claim Rewards

Earn Stars based on your damage share when the Sun finally falls, then reinvest them into boosts.

The Sun is a group effort - you don't need to solo it. Focus on maximizing your share of total damage.

Why Weak Points Matter

The Sun and its planets spawn weak points during the fight. Hitting a weak point deals bonus damage, which is the key to climbing the damage leaderboard and claiming a top reward share.

Without targeting weak points, your raw damage will lag well behind players who do - even if your holes are similarly strong on paper. The multiplier is simply that large.

Weak points also appear on planets and asteroids, so keep an eye on all targets during a fight rather than tunnel-visioning the Sun itself.

Keys to Topping the Leaderboard

Three factors that decide your Sun damage rank, and which of them you can improve before the next fight begins.

Optimize all three together to maximize your Star rewards rather than relying on hole power alone to carry your share of the damage leaderboard.

Hole Power

Stronger holes deal more base damage per launch, so climbing the tier list is the foundation of every Sun run.

Weak Points

Hitting weak points adds large bonus damage and is usually what separates leaderboard winners from the rest.

Boosts

Equip a Wormhole for extra attack damage that stacks on top of your hole power during the fight.

Don't waste weak-point windows - they're your biggest damage multiplier during a Sun fight.

Sun Fight Checklist

What to prepare before a Sun attack, so every launch deals its full potential damage and you don't waste attack windows.

Going in unprepared wastes your holes' damage output and hands the top reward shares to players who prepped properly before the fight started.

Sun Fight Tips

Quick pointers for better Sun performance across every fight.

Small adjustments to timing and targeting add up to noticeably larger Star payouts over a full event.

  • Earn Stars from the Sun via the Stars guide, then reinvest them into boosts that raise your damage further.
  • Protect your attacking holes with best-hole protection so a raid can't remove them mid-event.
  • Climb the tier list to deal more Sun damage over time, since stronger holes contribute a larger share every fight.
