Tether Grenades is an Index Mod for the PentaDEPenta.png Penta that causes launched grenades to stick to level geometry and pull nearby enemies. Additionally, grenades will stop bouncing from enemies, and will instead pass straight through them. It also adds delayed self-detonation to grenades.

  • Can be installed on the Secura PentaSyndicatePSPenta.png Secura Penta and Carmine PentaPentaCarmine.png Carmine Penta.
  • Tether Grenades do not make contact with enemy bodies, reducing contact damage to zero but gains infinite body punch-through.
  • Tether Grenades stick to level surfaces.
  • Increases in-air explosion damage by 1.2x, but deals normal damage if the granade lands and the tether activates.
  • Grenades will not tether Capture, Synthesis or Demolyst Targets.
  • Self-detonation occurs 10 seconds after landing.
    • Grenades can still be manually detonated.
  • Cannot be equipped at the same time as Napalm GrenadesMod TT 20px.png Napalm Grenades.


  • Multiple grenades can be used to substitute for Warframe crowd control abilities when not enough energy is present to cast abilities.
  • Grenades will explode on contact with water and Tar-Mutalist MOA's tar puddles.
  • Grenades still cause self-stagger with this mod equipped.
  • Can be considered as an alternative to FirestormMod TT 20px.png Firestorm, as it drags enemies that might be out of range into the blast zone.


  • If your Penta is silenced, this mod will cause it to act as though it didn't have the silenced property at all.
  • Adhesive BlastMod TT 20px.png Adhesive Blast can be equipped but has no effect. Tether grenades will always punch through bodies and stick to surfaces.
  • Grenades will stick to ragdolled enemies, such as those under the effects of abilities like SpellbindSpellbind130xDark.png Spellbind, BastilleBastille130xDark.png Bastille or LarvaLarva130xDark.png Larva, or those launched by Slam Attacks. Once the enemy leaves the ragdoll state, the grenade will be detonated.
    • Grenades will additionally stick to dead enemies, which can then be moved.
  • Tether and additional grenade glow effects are not influenced by weapon's energy color.
  • This mod reduces grenade flight speed. Terminal VelocityMod TT 20px.png Terminal Velocity or a Riven Mod that adds a bonus to flight speed can offset this.
