Starscourge Radahn turns a boss fight into a battlefield. You start far across the sand, arrows screaming toward you, with summon signs scattered between you and the biggest problem in Caelid. The trick is to treat the fight like a raid: survive the approach, keep the Festival fighters in play, and take short punish windows instead of trying to duel him clean.

This guide covers the mechanics of the Radahn fight only. It avoids quest, ending, and post-fight story spoilers.

Quick Answer

The easiest spoiler-free Radahn strategy is to enter around level 65 to 70, bring a well-upgraded weapon, summon every Festival ally you safely can, dodge the opening gravity arrows on foot, then use Torrent to avoid the arrow rain and phase 2 meteor. Radahn is especially vulnerable to Scarlet Rot, and Hemorrhage also works, so Rotten Breath, Rot Grease, rot weapons, or bleed weapons can shorten the fight.

If you want the safest plan, let the NPCs pull Radahn's attention, apply Scarlet Rot when he commits to a long animation, then ride wide and resummon fallen allies until you get another clean opening.

Preparation and Recommended Level

Most players should fight Radahn around level 65 to 70. You can win earlier with clean dodges or a strong status setup, but if his arrows or sword chains kill you in one hit, leave and come back with more Vigor, armor, or weapon upgrades.

Preparation Recommended target Why it matters
Character level 65 to 70 Gives enough health and damage for a fair fight without overleveling the encounter.
Vigor 30 or higher, more if you struggle Radahn has several attacks that punish low-health builds.
Standard weapon About +12 or higher You need real damage during short openings.
Somber weapon About +5 or higher Somber weapons scale on a shorter upgrade track, so +5 is a strong midgame target.
Status effects Scarlet Rot first, Bleed second Rot keeps damaging him while you dodge; Bleed rewards aggressive punish windows.

Best Tools to Bring

  • Rotten Breath: If you have the Faith and Arcane for it, this is one of the cleanest ways to pressure Radahn without staying under his blades.
  • Rot Grease or rot weapons: Useful for melee builds that can land a few safe hits while the NPCs hold attention.
  • Bleed weapons: Katanas, claws, curved swords, and other fast bleed options work well when you can attack during recovery windows.
  • Rowa Raisins: Keep Torrent alive if you plan to ride often.
  • Magic defense or physical defense buffs: His opening arrows deal heavy magic damage, while the blade phase hits hard with physical attacks.

Phase 1: Crossing the Wailing Dunes

The fight starts at long range in the Wailing Dunes after you enter through the Redmane Castle portal. Radahn fires gravity-charged arrows before you ever reach him, and this opening kills more players than the melee phase.

Dodge the Purple Gravity Arrows on Foot

Stay on foot for the first single arrows. Roll through each shot at the last moment, preferably forward or diagonally forward. Torrent is fast, but the single arrows track hard enough that a late roll gives you a cleaner answer than trying to sprint away.

Use the Battlefield Cover Once

The weapon piles and debris between you and Radahn can block a gravity arrow, but they break after taking the hit. Use them to buy time while you grab nearby gold summon signs, then keep moving.

Summon the Festival Allies

Gold summon signs appear across the sand. Activate as many as you safely can. These are Festival NPC summons, not Spirit Ashes, and their job is to split Radahn's attention long enough for you to close the gap or apply status. If an ally dies, their sign can reappear elsewhere in the arena, so keep scanning the dunes during the fight.

Mount Torrent for the Arrow Rain

When Radahn shoots a volley into the sky, a stream of arrows begins chasing you. Mount Torrent and ride sideways across the arena. Do not ride straight toward Radahn while the trail follows you. Once the NPCs get close and Radahn draws his swords, the fight changes into a melee encounter.

Phase 1: Melee and Torrent Tactics

Radahn's sword range looks unfair until you stop chasing his front. Your safest space is behind him, near his horse, or wide outside his combo range while an NPC has his attention.

If You Fight on Foot

On foot, you get reliable dodge rolls and can punish more precisely. Stay near his rear legs when possible, roll through sweeping attacks instead of backing straight away, and attack once or twice after heavy slams. If he uses a gravity pull, roll away from the follow-up rather than attacking into it.

If You Fight on Torrent

Torrent gives you control over spacing. Circle at medium range, wait for Radahn to finish a combo into an NPC, dash in for a hit or a status application, then leave. This works well for rot, poison, ranged attacks, and cautious melee builds. The downside is that a hard hit can knock you off Torrent and leave you exposed on the ground.

Best Punish Windows

  • After Radahn slams both swords down and pauses.
  • When he turns toward an NPC and commits to a long combo.
  • After a gravity explosion, once the damaging wave has passed.
  • During recovery after he drags his swords through the sand and finishes the swing.

Phase 2: Meteor, Gravity, and Resummons

At about half health, Radahn launches into the sky. Stop attacking and get ready to move.

Survive the Meteor

Look up and locate the fiery meteor trail. Mount Torrent, ride away from the landing path, and keep moving until the impact finishes. Do not try to block it. If you lose sight of him, ride wide and create as much distance as possible.

Respect the Floating Meteors

In phase 2, Radahn can summon four large rocks around himself. They may hover for a while before he fires them. Treat them as lethal. Keep terrain between you and Radahn when possible, sprint sideways on Torrent, or dodge at the last moment if you are on foot.

Keep Resummoning

Many Festival allies die during phase 2. Their signs can reappear in new spots across the dunes, including after the phase change. Ride wide, resummon, and let them rebuild pressure before you commit to another attack.

Watch for Purple Ground Waves

When Radahn drives his swords into the ground and gravity energy spreads outward, jump with Torrent or roll through the wave on foot. Running away often keeps you inside the danger longer. Cross the wave cleanly, then reset your position.

Build-Specific Tips

Melee Builds

Use the NPCs as your opening makers. Wait until Radahn turns away, hit his back or legs once or twice, then leave. Fast weapons with Bleed can do excellent work, but heavy weapons are still fine if you punish only the largest recovery windows.

Faith and Arcane Builds

Rotten Breath can carry the fight if you land the cloud while Radahn attacks a summon. Cast when he is busy, watch for the health bar to start ticking, and then focus on survival. You do not need to stand in front of him after Rot has landed.

Sorcery and Ranged Builds

Stay mobile and cast while the summons hold him. Avoid long casts unless Radahn is locked into an animation. If he looks at you, stop casting and move. His gap closers punish greedy ranged play.

Shield Builds

A shield can help against some physical pressure, but do not rely on blocking the biggest gravity attacks, the meteor, or long sword chains with low stamina. Block small hits, roll the big ones, and use guard counters only when you are sure the combo has ended.

Common Mistakes That Get Players Killed

  • Mounting Torrent too early: Use foot rolls for the first single arrows, then mount for the arrow rain.
  • Ignoring summon signs: The fight is built around the Festival mechanic. The NPCs are part of the strategy.
  • Attacking his front: His sword arcs cover a huge area. Work from behind or while he targets someone else.
  • Getting greedy after one clean hit: Radahn can turn mid-combo and catch you during a second or third swing.
  • Losing track of the phase 2 rocks: The floating meteors can sit quietly, then kill you when you relax.

FAQ

Can you use Spirit Ashes against Radahn?

No. Spirit Ashes are not available for the Starscourge Radahn fight. The gold signs in the arena are Festival NPC summons, and you can use them repeatedly as signs reappear.

Can you use Torrent in the Radahn fight?

Yes, Torrent is available in the solo fight and is useful for arrow rain, repositioning, resummoning allies, and escaping the phase 2 meteor. If you summon another player for co-op, Torrent is not available.

Is Radahn weak to Scarlet Rot?

Yes. Scarlet Rot is one of the strongest status options against Starscourge Radahn. Hemorrhage, Poison, and Frostbite can also affect him, but Rot is the standout because it keeps dealing damage while you focus on dodging.

What level should I be for Radahn?

Level 65 to 70 is a good target for most players. Level matters less than Vigor, weapon upgrades, and whether you use the Festival summons well.

Is Radahn optional?

For a basic playthrough route, Radahn is optional. Some major progression paths and later content require him, but this guide avoids those spoilers.
