Understand Flawed Streamline
Useful when…
- Add the listed Ability Efficiency bonus in a standard Warframe slot.
- Compare its 12% maximum bonus and base drain 2 with standard Streamline’s listed 30% bonus and base drain 4.
Effect
Flawed Streamline gives +3% Ability Efficiency at rank 0, +9% at rank 2, and +12% at rank 3. Standard Streamline lists +30%; Flawed Streamline cannot be equipped with it.
Application
It is a standard-slot Warframe mod with Naramon polarity and base drain 2. Its incompatibility list names Streamline. Standard Streamline has listed base drain 4 and maximum rank 5.
Rank investment and restrictions
Each fusion step costs 30 Endo and 1,449 Credits (0→1), 60 Endo and 2,898 Credits (1→2), then 120 Endo and 5,796 Credits (2→3). The final step raises the listed bonus from 9% to 12%.
Limitations and tradeoffs
- Its listed maximum bonus is lower than standard Streamline’s, while its listed base drain is also lower.
- The two mods are explicitly incompatible.
Common mistakes to avoid
- Expecting Flawed Streamline to reach the listed 30% bonus of standard Streamline.
- Planning to equip it together with Streamline.
- Treating the listed step costs as cumulative costs from rank 0.
