Quick Answer

Elden Ring Starscourge Radahn boss fight in Caelid Wailing Dunes

If you are struggling against Radahn:

  • Summon every available NPC

  • Use Scarlet Rot if available
  • Avoid fighting directly in Phase 2

Where to Find Radahn

Radahn is located in:

Redmane Castle, Caelid

The fight becomes available after the Radahn Festival begins.

Once the festival starts:

  • Use the lift
  • Activate the portal
  • Enter the Wailing Dunes

This transports you to one of the largest boss arenas in Elden Ring.

Radahn's Weaknesses

Scarlet Rot

Scarlet Rot is Radahn's biggest weakness.

Even a single successful application can remove a large percentage of his health.

Popular choices include:

  • Rotten Breath
  • Ekzykes's Decay
  • Rot Pots

Many players defeat Radahn almost entirely through Rot damage.

Bleed

Bleed performs well due to Radahn's large health pool.

Recommended weapons include:

  • Bloodhound's Fang
  • Uchigatana
  • Nagakiba

Summons

Unlike most bosses, Radahn is designed around NPC summons.

Ignoring them makes the fight dramatically harder.

Understanding the Festival Mechanic

The battlefield contains multiple summon signs.

These signs allow you to call warriors into the battle.

Important NPCs include:

  • Blaidd
  • Alexander
  • Okina
  • Patches
  • Lionel

The key mechanic many players miss:

Summons can be called again after they die.

This means the festival never truly ends.

Your allies can continuously pressure Radahn throughout the fight.

Phase 1 Strategy

Phase 1 begins at extreme range.

Radahn immediately starts firing enormous gravity arrows.

Most first-time players die before reaching him.

Dodging the Opening Arrows

There are three options:

Option 1: Use Terrain

Weapon piles and debris can block arrows.

This is the safest method.

Option 2: Dodge on Foot

Roll at the last moment.

Requires timing but is reliable.

Option 3: Mounted Approach

Possible but less forgiving.

Mistakes often result in death.

Closing the Distance

As you advance:

  • Activate every summon sign
  • Allow NPCs to engage first
  • Avoid rushing ahead

Your goal is reaching melee range with maximum support.

Radahn's Melee Attacks

Once engaged, Radahn uses massive sweeping attacks.

Common attacks include:

  • Double sword sweep
  • Spinning combo
  • Gravity slam

Most attacks have long windups.

Watch his shoulders rather than the weapons themselves.

Best Punish Windows

The safest opportunities occur after:

  • Gravity slam recovery
  • Long spinning combo finish
  • Missed leap attacks

Do not stay in front of Radahn for extended periods.

His follow-up attacks are extremely dangerous.

The Phase 2 Transition

At roughly 50% health:

Radahn suddenly disappears.

Many players think the fight has bugged.

It has not.

He is preparing one of the most iconic attacks in Elden Ring.

After disappearing:

Radahn launches himself into the sky.

Seconds later he returns as a living meteor.

This attack can instantly kill many builds.

How to Survive

The moment Radahn leaves:

  • Get on Torrent
  • Sprint continuously
  • Watch the sky

Do not stop moving.

The impact zone tracks your position.

Constant movement makes the attack easy to avoid.

Phase 2 Strategy

Phase 2 introduces:

  • Stronger gravity magic
  • Faster aggression
  • Larger AoE attacks

Many players try to fight aggressively here.

That is usually a mistake.

Safer Strategy

Continue using summons.

Allow NPCs to distract Radahn.

Attack only when opportunities appear.

This dramatically reduces risk.
