Plan B

Conclave bow mod that briefly speeds secondary fire after a hit

Released Oct 21, 2015

Plan B grants a short-lived Secondary Weapon Fire Rate bonus when you hit with a bow. Consider it in Conclave when you can follow bow hits with secondary fire during the brief bonus window.

Plan B GUIDE

Understand Plan B

Useful when…

  • Pair bow hits with a secondary weapon you can fire during the duration.
  • Use it when the hit-triggered fire-rate boost is more useful than a bow-focused alternative.

Effect and trigger

At rank 0, a hit grants +5% Secondary Weapon Fire Rate for 0.75 seconds. Rank 2 grants +15% for 2 seconds, and rank 3 grants +20% for 3 seconds. The effect is triggered by a hit and applies to the secondary weapon; it does not state a bonus to the bow's own fire rate.

Compatibility and rank investment

Plan B is a Rare Conclave Bow Mod for a standard slot, with Madurai polarity and base drain 10. Its maximum rank is 3. The listed 2-to-3 fusion step costs 120 Endo and 5,796 Credits, extending the effect to 3 seconds and raising the bonus to 20%. The listed source is Rotation A in several Conclave activities on Neptune and Saturn, each with a 2.48 chance.

Alternatives serve different purposes

Soaring Strike grants +50% fire rate while airborne, whereas Plan B triggers a smaller secondary-weapon bonus on a bow hit. Arrow Mutation converts secondary ammo pickups to 50% of an ammo pickup, and Feathered Arrows trade +60% projectile speed for -20% damage. These address different conditions, so consider them only if their specific effect fits the loadout.

Limitations and tradeoffs

  • Requires landing a bow hit to activate, and the bonus lasts only 3 seconds at maximum rank.
  • Uses a standard bow slot and has base drain 10.

Common mistakes to avoid

  • Do not expect the fire-rate bonus to improve the bow itself.
  • Do not rely on the maximum-rank duration before ranking it; lower ranks have shorter windows.
