Mythic Storm King Not Dropping a Mythic Weapon? Fixes
If you have the Mythic Storm King not dropping a Mythic weapon after a successful clear, the first thing to check is quest eligibility. The boss does not hand out an unlimited Mythic schematic on every kill. Your first reward is tied to Regicide; repeat rewards are tied to the weekly Scions prequest and the weekly boss quest.
This means a technically successful boss run can still be a rewardless Mythic run if you entered before completing the required prequest. The fix is not to farm the boss repeatedly. The fix is to complete the correct quest first, verify it is active, then clear the boss again.

- Open the quest log before entering the portal.
- For the first weapon, verify Regicide is active.
- For later weapons, complete the current Scions of the Storm King quest.
- Confirm the weekly Defeat the Mythic Storm King quest appears.
- Beat the boss and collect the Mythic Schematic Cache from the arena.
- Return to Homebase and check the awarded schematic.
The weekly prequest was not complete
The most common reason for Mythic Storm King not dropping a Mythic weapon is entering the fight before Scions is finished. The weekly prequest is the eligibility gate.
Complete the assigned 140+ objective first, then make sure the weekly boss quest is visible.
You already used this week’s reward
Mythic weapon rewards are tied to the weekly quest cycle. If you already completed the current weekly boss quest, another clear in the same cycle is not another guaranteed Mythic schematic.
Check Weekly Quests before assuming the drop system is broken.
You did not collect the cache
The Mythic Schematic Cache appears as a drop after an eligible kill. If you leave the arena without collecting it, you can create a very different problem from the quest simply not being active.
Stay alert after the kill and pick up the cache before the mission finishes.
You are fighting the wrong Storm King
The Canny Valley Storm King and other normal Storm King encounters do not provide the Twine Mythic weapon cache. If you see Mythic Storm King not dropping a Mythic weapon, confirm the fight was the actual Twine Mythic portal.
Only the Mythic Storm King is the source of the five Mythic schematics.
Quick answer
For Mythic Storm King not dropping a Mythic weapon, verify Regicide or the weekly boss quest is active before the run, then collect the Mythic Schematic Cache after the kill.
Epic says Mythic weapons drop exclusively from the Mythic Storm King through its challenge system. See the official roadmap.
The safest habit for avoiding Mythic Storm King not dropping a Mythic weapon is simple: quest log first, portal second. Never assume a boss clear is reward-eligible without checking.
Before your next attempt
Before another run focused on Mythic Storm King not dropping a Mythic weapon, check the exact prerequisite, weapon role or fight transition described above instead of changing several things at once. Make sure the quest counter has updated in Homebase, repair and reload the weapons you actually need for this phase, carry enough materials for movement and horn access, and confirm the whole squad knows what happens immediately after the current objective is finished.
This matters because Mythic Storm King not dropping a Mythic weapon is usually lost at the transition rather than during ordinary Husk clearing. A team can have enough raw damage and still fail because crystal five was triggered with someone down, a Mini-Boss was left alive, the horn weapon was not ready, or the reward quest was never active. Fix the exact failure point, then repeat the attempt with the rest of the setup unchanged so you can tell whether the change worked.
For Mythic Storm King not dropping a Mythic weapon, keep the objective tied to the actual progression gate or fight mechanic described above. Check the quest state before launching, make the transition deliberately, and verify the result in Homebase before repeating the same step.
