Set Bonus[]

This mod is part of a set, whose set bonus increases with each additional mod equipped from that set.

Synth Set: Any primary or secondary weapon will automatically reload X% of their magazine (using reserve ammo) per second while holstered.

Mods Equipped Percentage Reloaded
1 5%
2 10%
3 15%
4 20%


  • An unlisted benefit to this mod is that it allows for all Health Orbs to be picked up without needing to be below full health.
  • If you're knocked down, your weapon is forced into its holster and begins automatically reloading.
  • The armor bonus is applied after Mod TT 20px.png Link Armor and Mod TT 20px.png Metal Fiber. In other words, at max rank, this mod can double the modded armor of companions.
  • It currently does not function any differently if an Empowered Health Orb is obtained, instead providing the same benefit as if a regular Health Orb was obtained.


  • Thanks to the unlisted benefit mentioned previously, this mod allows for fantastic synergy between other mods such as Mod TT 20px.png Health Conversion and Mod TT 20px.png Equilibrium.
    • Ideal frames that can make the most benefit of this synergy are ProteaIcon272.png Protea, RhinoIcon272.png Rhino, NezhaIcon272.png Nezha, and NekrosIcon272.png Nekros for either having the ability to quickly generate Health orbs and/or using abilities that scale off of current armor values.
  • This mod naturally works well with the other companion mod of the same set: Mod TT 20px.png Synth Deconstruct.
  • Synergizes with ArcanePulse.png Arcane Pulse, increasing the amount of health that can be obtained from picking up health orbs.
