The Raiden Sword (Raiden / Raiden Shogun weapon) is a strong mid-to-late-game weapon inspired by Raiden Ei/Shogun from Genshin Impact. It features polearm (single-target) and sword (AoE burst) modes. It is highly rated for DPS farming and competes with top options like Aizen in its tier. It requires the Archon Race and materials from the Raiden boss.
Requirements to Unlock
- Archon Race (mandatory; provides buffs including +20% Sword Damage, +10% Crit Damage, +5% Raiden Damage, +5% Overall Damage).
- Materials + currency (see below).
- Recommended: High level (roughly 2,000–2,500+), strong boss-farming build, Haki (for ~25% damage boost), and good mobility/AoE for efficient clears.
Purchase requirements (Raiden Seller NPC on Frostborn Island, left of spawn):
| Requirement | Amount |
|---|---|
| Puppet Core | x3 |
| Electro Vision | x1 |
| Tear of Eternity | x5 |
| Shard of Calamity | x8 |
| Celestial Steel | x85 |
| Coins | 7,500,000 |
| Gems | 7,500 |
(Note: Exact currency amounts can vary slightly by patch—confirm in-game at the NPC. Some community/trade listings show slightly different material counts, so verify the prompt.)
Materials & How to Farm Them
All materials (and the God of Eternity title) drop from the Raiden Ei boss inside the Plane of Euthymia dungeon/raid.
Boss drop rates (approximate; higher difficulty may improve odds):
| Drop | Chance |
|---|---|
| Celestial Steel | ~24.3% |
| Shard of Calamity | ~10.8% |
| Tear of Eternity | ~8.1% |
| God of Eternity Title | ~6.75% |
| Puppet Core | ~4.995% |
| Electro Vision | ~1.755% |
The boss has very high HP (reported around 110 million). Expect multiple runs due to low rates on rarer items like Electro Vision and Puppet Cores.
How to access Plane of Euthymia:
- Go to Frostborn Island.
- Farm Snow Bandits (or the Snow Bandit Boss) for Shrine Keys (low drop rate, ~1% from the boss in some reports). You can also exchange for keys at the Monument Isle Tower Exchange NPC.
- Use a Shrine Key to open the portal to Plane of Euthymia.
- Clear the waves (reports vary between 5 and 10 waves; enemies keep spawning—clear quickly).
- Defeat Raiden Ei at the end for drops.
Join public groups for faster clears if needed. Use Haki and a strong build.
Unlock Steps
- Reach a suitable level and obtain the Archon Race.
- Farm Shrine Keys on Frostborn Island from Snow Bandits.
- Enter Plane of Euthymia repeatedly and defeat Raiden Ei until you have all required materials (plus preferably the God of Eternity title).
- Gather 7.5M Coins and 7.5k Gems.
- Go to the Raiden Seller NPC on Frostborn Island (left of spawn).
- Hand over the materials + currency to unlock the Raiden Sword permanently.
- Equip it from your build/weapon menu.
Mastery (Full Potential / Armor / Skills)
After unlocking, talk to the Raiden Mastery NPC (at the back of Frostborn Island) and complete these quests:
- Obtain the God of Eternity title (from defeating Raiden).
- Have the Archon Race.
- Deal 1,000,000,000 (1B) damage with the Raiden Weapon.
- Clear the Plane of Euthymia dungeon/raid 15 times.
Completing mastery unlocks stronger skills/armor and full potential. The God of Eternity title also gives +15% Raiden Damage.
Tips for Faster Unlock
- Prioritize Celestial Steel (most common but you need many) while grinding the rarer cores/vision.
- Use a high-DPS farming weapon/style first (e.g., something with strong AoE) to clear the dungeon efficiently.
- Stock up on keys before long sessions.
- Confirm current requirements and drop rates in-game or via the official Trello/Discord, as updates can adjust numbers.
- Archon Race is key for both unlocking and maximizing Raiden’s performance.
Once unlocked and mastered, Raiden is excellent for progressing into higher-tier content thanks to its mode-switching burst potential. Good luck with the grind!
