Spring-Loaded Blade

Status-triggered melee range mod

Released Oct 12, 2017

Spring-Loaded Blade temporarily increases melee range after a status effect, stacking twice. Consider it for a melee weapon that can trigger status effects often enough to maintain the range bonus.

Understand Spring-Loaded Blade

Useful when…

  • Extend melee range after triggering a status effect.
  • Use the two-stack limit and 24-second maximum duration to support sustained melee use.

Trigger and duration

At rank 5, a status effect grants +1 Range for 24 seconds, stacking up to twice. At rank 0, it grants +0.2 Range for 4 seconds. The bonus is triggered by a status effect, so it is conditional rather than a permanent range increase.

Rank investment and fit

This standard Vazarin melee mod has base drain 4 and reaches rank 5. The listed Endo costs per step are 30, 60, 120, 240, and 480, while credit costs rise from 1,449 to 23,184. Rank 3 grants +0.7 Range for 16 seconds. Higher ranks improve magnitude and duration, so rank according to how reliably your weapon triggers status effects and how much sustained range matters.

Related effects and acquisition

Galvanized Elementalist adds status damage and can grant status chance after melee kills; it does not provide the same range bonus. Berserker Fury instead grants attack speed after melee kills, while Blood Rush scales critical chance with combo multiplier. Listed sources for Spring-Loaded Blade include Plains Commander, Narmer Thumper Doma, Tusk Thumper Doma, and specified Duviri Endless tiers.

Limitations and tradeoffs

  • The range bonus requires a status effect and expires after its listed duration.
  • It uses a standard melee slot with base drain 4.

Common mistakes to avoid

  • Do not treat the range increase as permanent; it lasts 24 seconds at maximum rank.
  • Do not assume the two stacks happen without further status-effect triggers.
