Fused Reservoir

Wisp Reservoir augment

Released May 12, 2021

Fused Reservoir adds a fourth Reservoir that provides all three Reservoir effects. Consider it when consolidating those effects into one Reservoir is worth its increased Energy cost and an Exilus slot.

Understand Fused Reservoir

Useful when…

  • Place a single Reservoir that gives the effects of all three Reservoirs.

Effect and cost

The augment adds a fourth Reservoir with the effects of all three existing Reservoir types. It costs 300% more Energy at rank 0, decreasing to 250% more at rank 2 and 200% more at rank 3. It does not remove the stated Energy premium at maximum rank.

Slot and investment

Fused Reservoir is a Zenurik-polarity Wisp Exilus mod, with base drain 6 and three ranks. The listed fusion steps cost 30, 60, and 120 Endo, plus 1,449, 2,898, and 5,796 Credits. Rank it further if lowering the extra Energy cost matters enough for the build.

Other Wisp augments

Critical Surge changes Breach Surge: teleporting to a Reservoir costs 50% Energy and grants Primary Weapon critical chance per meter traveled for nine seconds, up to 250%. Cataclysmic Gate changes Sol Gate into a single blast and leaves an area dealing 500 Heat damage per second with guaranteed Heat and Radiation status effects for 10 seconds. These modify different abilities and are not substitutes for the combined Reservoir effect.

Limitations and tradeoffs

  • The combined Reservoir effect has a substantial extra Energy cost at every listed rank.
  • It occupies the Exilus slot.

Common mistakes to avoid

  • Reading the 200% increase at max rank as no extra Energy cost.
  • Confusing the Reservoir augment with other Wisp augments that modify Breach Surge or Sol Gate.
