Understand Mad Stack
Useful when…
- Increase K-Drive velocity during falling.
- Use it when falling speed is the specific K-Drive property you want to improve.
Effect and rank scaling
Mad Stack grants velocity while falling: +20% at rank 0, +80% at rank 3, and +120% at rank 5. The stated bonus is conditional on falling; no effect outside that condition is specified.
Equipment and slot
This is an Uncommon, standard K-Drive mod with Madurai polarity, maximum rank 5, and base drain 4. It is compatible with K-Drive.
Fusion investment
Higher ranks raise the falling-velocity bonus, and the listed fusion costs grow at later steps. For example, rank 0 to 1 costs 20 Endo and 966 Credits, rank 2 to 3 costs 80 Endo and 3,864 Credits, and rank 4 to 5 costs 320 Endo and 15,456 Credits. Invest toward rank 5 if the full listed bonus is useful; a lower rank costs less to fuse.
Related K-Drive effects
Air Time reduces gravity while falling, which changes a different stated property. Kinetic Friction charges while grinding and releases Electricity damage on landing a trick. Bomb The Landin' enables a slam shockwave by tapping and holding Grind in the air. These are distinct effects, not replacements that reproduce Mad Stack's falling-velocity bonus.
Limitations and tradeoffs
- Higher ranks increase the effect but have increasing listed fusion costs.
Common mistakes to avoid
- Assuming the falling-velocity bonus applies during all K-Drive movement.
- Confusing Mad Stack's velocity bonus with Air Time's gravity reduction.
