Warframe Basmu Guide 2026: Best Rifle Build and Tips
Basmu is an event weapon, but it can be traded between players and becomes more powerful through the 'Dreadful Killshot' augment mod obtainable from Nightwave. This guide introduces how to obtain Basmu, its features, and various builds.
1. How to Obtain: Limited-Time Event, But Tradeable!
- ✅ Basmu is not a weapon that can be obtained at all times, but a limited-time event weapon.
- ✅ It can be obtained from major events such as 'Scarlet Spear' and 'Orphix Venom', and usually reappears during the October 'Knights of Nberus' Halloween event.
- ✅ The 'Blood of Parita' event has recently ended, so it cannot be obtained at the moment, but it can be traded between players.
- ✅ You can purchase Basmu blueprints cheaply on Warframe Market.

2. Basmu's Features: Laser Projectiles, Beam Mode, and Unique Reload System
- ✅ Basmu is a fully automatic rifle that fires laser projectiles.
- ✅ Unlike what it looks like, it has projectile judgment like Exilus and causes an explosion that deals 1.7m range of heat damage.
- ✅ Secondary fire fires a continuous laser beam, and the beam connects to nearby enemies.
- ⚠️ The beam tends to stick to enemies, making headshots difficult.
- ✅ There is no ammo capacity, but it has a magazine of 21 rounds.
- ✅ It automatically recharges if the magazine is not completely emptied.
- ✅ Emptying the magazine completely staggers nearby enemies and emits an energy wave that restores your health.
| Feature | Description |
|---|---|
| Primary Fire | Focus on status effects, electric damage |
| Secondary Fire (Beam) | Low critical chance (2%), but very high critical damage multiplier (4.8x) |
Basmu has two main play styles.
- A style that focuses on primary fire and aims for direct hits
- A style that increases critical chance to compensate for the low critical chance of secondary fire

3. Essential Mods: Dreadful Killshot, Galvanized Aptitude, Primary Acuity
- ✅ Dreadful Killshot: A Basmu-exclusive augment mod that increases base damage and status chance based on the Warframe's current health (up to 360%).
- ✅ To get the maximum effect, the Warframe's health must be 1350 or higher.
- ✅ For Warframes with low health, it is recommended to use Arcane Blessing to secure health.
- ✅ Galvanized Aptitude: Because Basmu's primary fire is a projectile, the damage bonus is applied multiplicatively upon direct hit.
- ✅ Primary Acuity: Increases critical chance and weak spot attack damage, making it useful for headshots.

4. Optimal Warframe: Harrow
- ✅ Harrow has very good synergy with Basmu.
- ✅ Covenant (4th Ability): Greatly increases critical chance and instantly triggers red crits on headshots.
- ✅ Thurible (2nd Ability): Increases attack speed and reload speed.
- ✅ Condemn (1st Ability): Can bind enemies to make headshots easier.
09:32 - 10:45
5. All-Round Build: Electric Status Focus
- ✅ You can respond to various enemies by replacing faction damage mods.
- ✅ Focus on electric damage and sustained damage.
- ✅ Maximize electric status effects through high base status chance, Dreadful Killshot, and Primary Crux.
- ✅ You can use Guided Ordinance (Exilus Mod) to increase headshot accuracy.
- ✅ Secure critical chance through external buffs (Arcane Avenger, Harrow) and focus on critical damage mods.
10:48 - 12:16
6. Red Crit Build: Maximize Headshots
- ✅ Focus on headshots with primary fire, rarely using secondary fire.
- ✅ Use Primary Acuity to increase weak spot attack damage.
- ✅ Increase status chance and damage by using Dreadful Killshot, Elemental List, and faction damage mods.
- ✅ Further increase headshot multiplier and reduce recoil by using Primary Deadhead.
12:17 - 12:51
7. Alternative: Build that Requires Fewer Headshots
- ✅ Use a multishot mod instead of Primary Acuity.
- ✅ Arcane slots can be freely selected (Primary Bullwark, etc.).
12:52 - 14:29
8. Blast Nuke Build: Wide-Area Explosion Damage
- ✅ Causes wide-area damage by inflicting blast status effects simultaneously with headshots.
- ✅ Killing an enemy with a blast status effect inflicts blast damage on nearby enemies.
- ✅ Similar to Exilus, but Basmu has a high status chance, so the probability of inflicting blast status effects is high (60% or more).
14:30 - 14:43
9. Alternative: Blast Build that Requires Fewer Headshots
- ✅ It is not necessary to focus on headshots, but it is still recommended.
